How To Use the HB3x2 with a Basic Stamp 2
We are going to connect the Basic Stamp 2 to the HB3x2 with 2 standard I/O pins and 2 PWM outputs. We have chosen Pin1 and Pin3 as the standard I/O pins and Pin2 and Pin4 as the PWM outputs.
We will use Pin1 and Pin2 for Motor1, and Pin3 and Pin4 for Motor2.
We will consider Pin1 high as forward for motor1, and Pin1 low as reverse for motor1. Likewise we'll consider Pin3 high as forward for motor1, and Pin3 low as reverse for motor1. This may not be the same as your hardware so you may have to change this in your code.
Basic Stamp Hookup Diagram
For this code we are going to wire up the circuit as follows:
