MEMS 2-Axis Accelerometer

I picked up a Memsic 2-axis accelerometer from the sensor drawer at radio shack. I’ve never used an accelerometer before and this one uses MEMS technology. I hooked it up to my BS2-IC via breadboard and uploaded a maze game. … Continue reading

Adding a Parallax Ping to an AVR using C

Introduction I chose to go with the Parallax Ping Ultrasonic Sensor for this upgrade to my robot. Though only tested on an ATmega8, 168, and 128 this should port over to any AVR 8-bit RISC microcontroller. The reason I chose … Continue reading
