Hi everybody I am planning to make a car using the particle photon 1 microcontroller. Atleast something that can run. I wanted to see if anybody with a foundation with this microcontroller knew what type of schematic works because I tried to use the digital pin D7 to send a signal to the positive end of the motor and the negative end of the motor conneted to ground but it does not supply enough of a signal to run the motor. How can I go about fixing this issue since I know the motor works with power and ground?
You could make your own circuit with transistors to be able to drive the higher current, and possibly higher voltage. There are also DC motor controllers that include the necessary circuit and you just connect it to two PWM outputs on the Particle device.
You will probably also need an external power supply when using an external motor.
