Motors and Servos and Solenoids, OH MY (rev2).

Posted by & filed under Dorkbot.


On Sunday the 25th I am going to do an animtronicx workshop covering driving
motors, servos and relays with the arduino/wiring platform.
I will be covering the a couple of popular chips: The l293D for
driving motors , and the ULN2803 darlington array for driving relays,
stepper motors and other devices.
The workshop will cost $35 and will include these chips, a motor, a standard sized servo and a board for the motor driver.

The idea is to get as much hands on and working as possible so please
