b'Circuit 5A:In this circuit, you will learn the basic concepts behind motor control. Motors Motor Basicsrequire a lot of current, so you cant drive them directly from a digital pin on the RedBoard. Instead, youll use what is known as a motor controller or motor driver board to power and spin the motor accordingly.PWMA AI2 AI1 ST BYMOTOR DRIVERGEAR MOTORSWITCH16 HOOKUP WIRES YOU BI1 BI2PWMB GND NEEDVM VCC GND A01 A02 B02 B01 MOTOR DRIVERGNDNEW COMPONENTS side of the motor.

The motorscontrol direction, and one controls speed), and then uses these signals to control the current through two wires attached to your motor.NEW CONCEPTSVOLTAGE IN (VIN): This circuit utilizes have a clever design allowing you to attachthe VIN pin found with the other RedBoard things that you want to spin fast (like apower pins. The VIN pin outputs a voltage small fan or flag) to the hobby motor, andthat varies based on whatever voltage the things that you want to be strong (like aRedBoard is powered with.
