How to Program an AVR/Arduino using the Raspberry Pi GPIO

This post will detail how to do it. I decided to write this because it took me days of searching and scratching my head to get it working and I though somebody else may find it useful. Some background first… I was putting together a internet connected installation that listened to twitter and I was very surprised by the responsivness of the twitter stream API. This got me to thinking that this would be a simple robust way to remotely control almost anything. It was around this time that I discovered that there was device coming out of China that was essentially a computer on a stick MK , they are marketed as Android powered media centres for your TV. They come with 1. If I could connect this device to an Arduino and run Processing apps it would be a awesome inexpensive way to create a internet of things platform that I could integrate into a sculpture or installation.

LESSON 23: Arduino GPS with Data Logger

As seen in the May QST! Why a Mobilinkd TNC? Low cost — much less expensive than existing purpose-built APRS gear.

Our Raspberry Pi cases are designed and manufactured in the United Kingdom using state of the art Injection Moulding, and all Raspberry Pi cases are made from tough, strong and durable ABS Plastic.

In case you are missing docs. The pack comes with an Arduino UNO and ton of components. It would probably be cheaper to buy components as I need them for my projects, but I like the convenience of a starter kit. I also purchased a GPS module from Digikey. The GPS receiver has a built-in antenna, but getting one with an external antenna would probably work best. The exact installation process is beyond the scope of this article.

I connected the Arduino to my laptop, installed the software and selected one of the samples Blink. After uploading the code to the Arduino, I had a led that was blinking every second: It can display 16 characters on two rows 16×2 and is compatible with the Hitachi HD , so I simply connected the display as explained on the Liquid Crystal tutorial.

I did not want to add a potentiometer to control the contrast, so I grounded Vo.

Fulfillment by Amazon (FBA) is a service we offer sellers that lets them store their products in Amazon’s fulfillment centers, and we directly pack, ship, and provide customer service for these products.

Ask Question Step Not So Uber Perhaps “uber” is too bombastic a title. No project is perfect. Here’s the list of deficiencies, from the most to the least glaring. I hope to address these some day. When I was making the gateway, I had some poorly soldered transceivers and lead to making me think there was a library conflict. I haven’t gone back to fix the problem It is sloppy claptrap programming on my part. I haven’t tried it yet.

Arduino Compatible Active Buzzer Module

I came across a UK based website called loveelectronics. They have a perfect little DS breakout board. In short any code that works with DS should work with DS without any changes. So with that out of the way let me give you a quick tutorial on getting this chip running, first the cabling.

Here at SparkFun, we refuse to leave ‘good enough’ alone. That’s why we’re adding to our line-up of Arduino-compatible microcontrollers once more! The Pro.

This is very important as you can’t get a location fix if you don’t have an antenna. Using this circuit I got a location fix indoors on the ground floor of a 2 story house in 1 to 2 minutes. Outdoors it got a fix in about 30s or less. Accuracy was very good, to within ft initially, and improving the longer you leave it it gets a new reading every second. The wiring of this diagram is straightforward. First you should set the voltage switch on your GPS shield to 5v before you power it on and connect it up.

Highlight the text below to see the answer When the button is held down, the Arduino prints out “Button just pressed” over and over again. When its released, nothing is printed Why does this happen? Go through the sketch, keeping track of what buttonState and val are storing at each line.

Almost Six months ago, I built my first data logger project on this website using an Arduino Nano and the DS Real Time Clock, a few weeks later, I posted the idea of building an improved version of the project on the website here along with many other project ideas, most of the visitors voted to build this project first, so here it is!

I really want to communicate wirelessly between Arduinos for cheap. The problem is the cost. Zigbee modules seem to be the standard, but they are just too much to be a reasonable solution for putting everything on the Internet. The Nordic nRF24L01, built into a small module and sold by mdfly. It entirely implements the Data Link Layer in hardware, handling addressing, collisions, and retry, saving us lots of work on the software side. Zigbee has the brand recognition, but this little guy puts it to shame.

This library is designed to be Maximally compliant with the intended operation of the chip Easy for beginners to use Consumed with a public interface that’s similiar to other Arduino standard libraries Built against the standard SPI library. If you want to understand what you can do with this “little” radio, download the data sheet.

Module Learning Kit for Arduino

I will be focusing on what projects you can use the Arduino for, Arduino shields, physical computing and interaction with the real world using various types of sensors and actuators. Some focus would be on Arduino in Malaysia like where to obtain electronics parts, gathering, workshops and meetups. Please join the facebook group for discussions, additional project photos and information sharing among beginners.

It’s blue! It’s thin! It’s the Arduino Pro Mini! SparkFun’s minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader.

Just because the stripes are in a certain order doesn’t mean the resistor has a direction! Resistors are the same forward and backwards, it doesnt matter which way they are used. Highlight the text below to see the answer Red – Red – Brown – Gold What is the value of this resistor? Highlight the text below to see the answer Ha!

Trick question, it is not possible to put a resistor in ‘backwards’. They work either way! Say hello to the LED! We’ve had some time with the LED already, but lets get to know her a little better. The light-emitting part, well, that makes sense. We’ve used the LED to make a blinking light in lessons 1 and 2. The LED component turns current into light, much like any sort of light bulb.

But what is this mysterious diode? A diode is basically a one-way street for current.

This also works well for the Water Pumps used in PC Water Cooling as well as any dc pump or fan that has a rotation sense wire. All we have to do is use the arduino to do is count that data, do some math for us, and output the converted data onto an LCD Screen. This signal can be used to tell fan controllers or motherboard inputs how fast the fan’s blade is tunring. In our case we are going to use this to tell the Arduino how fast the fan is spinning. While a nice feature for safety, it will be much cooler to see the RPM at which your fan is running than knowing your CPU wont melt if it dies right?

PS2 connector is used for powering Gmouse and for getting data in PS2 data line. If the GPS receiver is new, or has not been used for some time, it may need 15 minutes or so to receive a current almanac. Choose the appropriate COM port that got assigned to the explorer in your system by looking into the device manager like as shown below. In this figure you can see communication port COM1 got selected: Those spheres only intersect at only one earth point your location.

If there were only 3 satellites, there is more then one place the spheres intersect which is why the system needs that forth satellite so a bad calculation can not be made. The GPS receiver needs 4 satellites to work out your position in 3-dimensions. GPRMC tells the latitude, longitude, speed, time and date.

Encoder Library

This includes the 1. It also can transmit on MARS bands. Getting your Ham license is easy too! All that is required is a Technician license: You could even invent your own digital modes with enough skill. It is compact, lightweight, and works great with any Arduino or Arduino compatible that supports Uno-style shields.

Connecting GPS-module to Arduino: This is a simple Instructable for the people who’d like to know how to connect and use their GPS module with an Arduino. I am using an Arduino Duemilanove and an EMA GPS module. NOTE: The breadboard is not necessary but makes the job a lot ea.

A LCD module is a character based liquid crystal display LCD that is used commonly to display status in control panels or a simple way to interface with human in a parking payment machine. These display are considered ancient in today offering of colour based and large screen touch sensitive display found everywhere from ATM to control panels for home automation. Here are some information I found out. There are smaller or bigger combinations but these two are the most commonly found in stores or online.

For Arduino, there are a few ways to add a LCD to your circuit. First method is to buy a LCD shield, the second method is to buy a LCD module, solder the header pins and hook it up to a breadboard. The pins are either one single row on the top or bottom of the module or 2 rows of 8 connectors located at the side of the module.

I will go over the LCD pinout and will be focus more on how to connect them up to an Arduino using the common 4bit mode. You will only use up 6 digital pins from the Arduino. The LCD module should come with a datasheets that have the following pinout. I will translate the datasheets information into english as most datasheets are very hard to read or understand for beginners!!! Put a correct resistors between either pin 15 or 16 to limit the current. You will need to refer to your LCD datasheet for the backlight forward voltage Vf and forward current If.

The formula for the resistor to use is:

This looks like it may be the way to go. Any insight or suggestions would be great. So, with that in mind, I think a purpose-designed diode or sensor would probably work better. Are you intending to measure how much light, of a longer wavelength, is being received? I want to measure cumulative exposure over a period of several mins to several hours to account for varying light levels that would be encountered on, for example, a partly cloudy day.

pcDuino3 Nano is a high performance, cost effective single board computer. It runs operation systems such as Ubuntu Linux and Android. pcDuino3Nano has HDMI interface to .

Using some sort of web-server directly on ESP e. Inspite of a plethora of posts online it turned out to be very hard for me to get this to combination to work. I spent atleast days until I actually got this right. The main problem I see is that a lot of the solutions online are actually down-right incorrect, not-recommended or for other similar boards e.

Also there are a few gotchas that were not commonly called out. The steps to make a Uno and Nano work is different from them. Power Supply ESP is powered by 3.
