Access Control Lists (ACL) Mobile Backend Services are awesome, but sometimes you need them to be limited to some users. Thats where Access Control Lists (ACL) come in. The ACL object implements access control lists for mobile backend service objects. An access control list controls read and write access to any mobile backend service objects
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
