I have fried my 4 channel motor driver and don't know how this can happpen. As you can see in the picture the Dual FET IC U10 for motor 4 is blown away. This happened during a first test of my IOIO-SHR v2 robot. Before connecting the motor driver the program has been tested with an oscilloscope, all Outputs are working as expected. All connections has been double checked. Power supply testet with an voltmeter. Each PWM pin can be controlled from the Android phone with a Slider of my test app. PWM frequency was 1kHz.
Google plus is the new social network platform and has been launched as Beta last week. It's a little bit tricky to get an invitation for an account. If someone is interested to get an account, I can help.
Justin is a robot developed at German Aerospace center DLR. I saw him at CeBit 2009 (2nd video), where he is serving ice tea. Now he learns some new tricks, like catching balls or making coffee. Very impressive!
A brilliant tutorial, I think, with video about motors ad microcontrollers from nerdkits.com. Learn about how a motor works, EMF, use of flyback diodes, control a motor from a microcontroller, PWM etc.
