2013/09/14 Arduino Training and Hacking at Google
π 2013-09-14 01:01 in Arduino, Google
I was able to join an arduino 101 class at Google today. Ok, I wasn't an arduino neophyte, but there are a few useful things I learned during the class, and more importantly got to hack on new IO devices (I2C LCD and I2C LED matrix) which I had never interacted with before, as well as with an IR distance sensor which has pluses I was not aware of compared to the ultrasonic sensors.

I had good time hacking with this, and in the end was able to make a game where you keep a ball inside the square with an accelerometer while another person can adjust the game speed with the IR sensor. When you lose, you get appropriate sound and screen animation (doesn't look like much, but this is usually what takes the most coding time).

Here's my demo to my coworkers, using my external clean power supply:

And the same thing in a small form factor, using the noisy arduino voltage ref (this is why it's moving so much in the init phase, despite no input). I'll have to do some analog electronics to clean that up:

This was definitely time well spent and a good learning experience.
