Your motor runs 185 RPM at the output, the gear ratio is 20:1 this gives an encoder RPM of 3700. The motor encoder pins labeled Hall VCC and Hall GND should be connected to the Arduino 5V and GND pins. DC motors are one of the commonly used motors in different applications like electronic toys, power tools, portable fans, etc. If you use an encoder it will indicate the current position that gives pulses to let the Arduino know that the shaft has turned one step and in which direction. So in this first Arduino sketch it reads the state of the rotary encoder pins when we rotate it and displays those values on the serial monitor. The motor driver/encoder connects to the Arduino shield via an RJ45 connection. I think that this program wil count the pulses every half a second. Description: This is a breakout board based on LS7366R quadrature counter IC. With a car platform, add s…. There are two channels in quadrature, so you can detect direction, but that probably isn't important for this, since the rotation is going to be determined by the polarity of the applied voltage on the motor. motor; encoder; controller; pid; Reference Home. Use an if statement to tell the motor to change speed only if the value is greater than the minimum speed needed to spin the motor, as follows: (a). All the parameter above is tested without load. They used to often be seen in industrial settings mounted to the back of DC motors and coupled to the motor’s shaft with a coupling. const int Encoder_Pin = 2; // output of encoder to interrupt #0, pin 2 of arduino.
