Another project I did for a friend of mine was called “Rick Roll”. It’s basically a board that just plays a Rick Astley song. /* This sketch uses the buzzer to play songs. The Arduino’s tone() command will play notes of a given frequency. We’ll provide a function that takes in note characters (a-g), and
So my 5050 lights came in and they are a little bigger than I thought they would be. So now I had to remove the second RGB lights I had put in. I did find a small error with the power supply. It was hooked up backwards. Glad I triple checked that. I also double
FIRST STEP One of my first projects I wanted to try was a mood light. I’ve seen a number of these on the internet, so I thought I would try my hand at one. Ok, I know its not the most difficult project, but baby steps. The first thing I did was design my board.
The other day I was on Ebay looking for small microcontroller to put into my projects. I was looking for the cheapest, smallest (TQFP package), most bang for my buck microcontroller I could find. I came across this ATMega88P-20AU deal . Five for $11.45 or best offer. So I offered them $10 and two and a half
So lately, I have had an interest in building something physical instead of just coding. So I have been building electronic “things” using my Arduino. While doing these projects I found that programing small chips while using an Arduino involved a lot of wires and connections. Why did it need to be so messy? How
