Servo Control with PICAXE-08 (NOT M)

One for TofuRobot.

 1.    The electronics:-

The Diamond on the left is the Picaxe pin, I normally use a resistor 100-200R just to protect the Micro just incase of short or plugging the servo in backwards (there are two types of people using servos, those who have plugged servos in backwards and those who are about too!).

Ardunio Motor Control

Hello all

 just a quick note on building a motor control board for your Ardunio, use the following circuite:

 

l293dmotorboard.jpg

 This will allow you to drive two motor forward and reverse using just a L293D, a 7404 and a few caps and resistors.

Note this is good for about 600ma continuious, so don't cook it!
