I was looking for a way to handle wireless communications between two Arduino boards. Other options like Xbee or Bluetooth were going to cost $50 to over $100. Then I found a cheap RF transmitter and receiver at Sparkfun. The total cost is only $9! Here are a few limitations to RF solution: Communications is […]
Using an ATmega 2560 and therefore the heart of Arduino, we have developed a universal remote control with GSM. This allows to control 2IN/2OUT, DTMF key, gate control and GSM thermostat activated remotely. We have already presented several remote control with different functions. But now we want to present the best remote control ever made
I have an Arduino Uno connected to two IR transmitters and respective receivers. Basically, when one of the receivers detects a beam break, I have a strand of LEDs display a pattern. This all works in principle, but the problem is that when the IR transmitters and receivers are connected to the Arduino, the LEDs

One of my colleagues, Dr. Shane Mayor, has built a very nice LIDAR system for atmospheric research. It’s located at a remote site, at the end of a dirt road, and everything about the system can be controlled remotely except the main pump laser power supply. That supply has a key-switch, which has to be
My students need to learn LabVIEW —I know, it’s proprietary software, and expensive, but until a viable open-source equivalent comes along we’re stuck with it— and one of the exercises I have them do is to make a program to analyze radioactive decay. This gives them experience in using counters, plotting data in real time,
This project used the Si470x FM radio receiver and an ardurino to make an over the counter kitchen radio. These parts had been purchased for a different build that unfortunately met a premature end. The concept for this project is simple. Play my favorite news and music radio stations while having a form factor that
Introduction August, 2007 One of my other hobbies is photography, and, about a year ago, I purchased a new digicam – a Panasonic FZ30. I joined the Panasonic forum on the dpreview site. One of the posters, a programmer and electronic hobbyist, designed a nifty wireless remote using a very inexpensive RF transmitter/receiver combination that he
What does a smart snow globe do? It tells you if tomorrow’s going to be a snow day! Is it snowing tonight? Will you have the day off from school or work tomorrow? Put this snow globe next to your bed when you go to sleep to find out. Then when you wake up in

Have you ever wanted to use a good old knob to control your TV volume instead of repeated button pushing? Or make it controlled by light? Do you want your remote to be replaced by an awesome arduino and let it do the hard work of using a remote for you? Well this instructable is

I’ve been visiting local convenience store (Dollarama, here in Montreal, Canada) and notice nice looking FM Radio, just for only $3. Why not to try to interface it to my lovely Arduino? Idea looks quite challenging, the same time what is the point in interfacing a DSP radio shield to arduino? I don’t need a
