I was looking for a project to do with my Raspberry Pi and found thisInstructable and thought I would have a go at something similar which worked with Google Play Music. I had a rough idea of what I wanted the final item to end up like and was able to get my dad interested in helping me with

I had a traffic light that I was refinishing. The only thing left to do was to build the controller for the light’s signal patterns. To give it a twist I incorporated a remote control. This was also the perfect opportunity for me to try out an Arduino. I wanted to use the Arduino becuase

I recently dug up my old RC transmitter and receiver and thought “How can i control my arduino with this?” so i powered on my scope to see what was going on at the receiver. Sure enough, it was sending out the standard PWM signal that servos use. Now I just needed something to control. What’s easy

Waveform generators (also called function generators) are useful for testing and debugging circuits. They can be used to test the frequency response of electronic components like op amps and sensors or to characterize and troubleshoot audio effects boxes and pedals. This waveform generator shield is powered by an Arduino. It outputs four waveforms: sine, triangle,

After I finished my last project, I couldn’t stop thinking how to build an AM receiver, that would also operate in conjunction with my little friend Arduino. To minimize a workload and complexity, especially with RF part of the circuitry, I come up to conclusion, that SDR (Software Defined Radio) is the best choice for

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

If you have read my first blog on the topic, than you already know what I’m experimenting with. Low price FM Radio, build with TDA7088 / YD 9088. It was obvious, that technology from the early 90-x is outdated. I mean, simple “search and hold” function of the radio. Scan function works only one way, up in

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

Interfacing a RC radio to a microcontroller is a bit of a pain, especially if you want a lot of channels, because you have to time each channel’s output individually. An AVR only has one 16 bit timer with two compare channels, so either you can only use two channels at full resolution or you

SOS is the commonly used description for the international Morse code distress signal (· · · — — — · · ·). [read more on wiki] Requirements: 1) Arduino 2*) 8 Ω speaker 3*) 150 Ω or similar resistor 4) 5mm RED LED 5) Hook-up wires 6) Any breadboard * Ω = Ohms Step 1:
