The MultiMoto is a 4 channel H bridge that lets you control the speed and direction of up to 4 actuators. It can supply 6 amps continuously to each channel while handling spikes up to 8 amps. It can take an input voltage of 6 - 36 volts.
In this Instructable, we'll be going over the basic functions of the MultiMoto, and learn how to use it to control our linear actuators. Due to the current limitations on each channel, it is only meant for use with our PA-14, PA-14P, and PA-11 actuators.
We will need:
Let's get started!
Step 1: Wiring the board
To start plug the MultiMoto shield into the Arduino.
Connect the actuators to the M1, M2, M3, M4 connectors. For our actuators if you connect the black wire to the right and red to the left, then in programming, 1 corresponds to extension and 0 corresponds to retraction.
Connect power from your 12V supply to the BAT terminal. Red to +, black to -
Power is transferred from the MultiMoto to the Arduino so there is no need to connect to Vin.
That's all there is to it!
