DC motor wiring

Connect one DC motor to OUT1A,OUT1B, the other to OUT2A,OUT2B.

DC motor control mode

Step motor wiring

  • Connect step motor to Microduino Motor module:
    • The four-wire two-phase step motor has two sets of coil A and B. Each group of coil's resistance is very small, only a few ohm.

A and B group are absolute insulated and disconnected. Just use a multimeter to measure, the one connected belongs to one group.

    • After identifying the A and B group, just connect one group to (OUT1A, OUT1B), the other to (OUT2A, OUT2B).

Application

Program download

Test program：File:Program Test A3906.zip

A3906 controls two DB motors

  • Use Microduino core and Microduino A3906's control function;
  • Prepared hardware: Microduino FT232R,Microduino Core, Microduino Motor and two DC motors as well as a power supply(2.5~9V);
  • Prepared software: Microduino test program(Arduino part) and Arduino IDE(version 1.0 and higher)；
  • Start Arduino IED，open the Microduino test program, choose "Microduino Core (Atmega328P@16M,5V)" and download directly；

How to make a pegboard with Microduino core and Microduino Motor connected：

  • Set up the circuit on pegboard as follows (blue line at the bottom)


Pegboard connection
  • Microduino Motor drive DC motor test:
    • Connect 5V or 9V power, the motor don't rotate initially:
    • Start Arduino IED serial monitor
      • Input 0000, enter, two motors don't rotate
      • Input 0101, enter, Two motors rotate forward
      • Input 0110, enter, one motor rotates forward and the other backward
      • Input 1001, enter, one motor rotates backward and the other forward
      • Input 1010, enter, two motors rotate backward
      • Input 1111, enter, two motors stop
