Transistor & Motor

This simple transistor motor circuit is based on ARDX-03.  It uses a number of new components that you will need to understand.  Start by gathering your parts together:

Step 1:  Build your Circuit.

Step 3:  Extensions

  • Currently you are running your motor at full speed but it can take any number between 0 and 255.   Change HIGH and/or LOW to another number.  What is the lowest number that actually turns the motor.  If the number is too low the motor will stall.
  • Write another method that accelerates the motor from its stall speed to its max speed.
