Descriptions A very low-cost stepper motor driver that has 4 modes of operation. Can be used for excellent robotics application without using any program. 1.Working Mode: Normal Mode 1: S1 start stop button, S2 forward and reverse button, W2 potentiometer speed control. If limit reversal is required, two limit switches can be connected to the P3 pin, and the motor motion shaft is mounted with contacts, so that the motor will reciprocate within the stroke between the two limit switches. 2. Normal Mode 2: S1 forwards the start button, S2 reverses the start button, press any button to stop. W2 potentiometer speed regulation. If the limit stop is required, two limit switches can be connected to the P3 pin, so that the motor will stop moving when it touches the limit switch, and the motor will reverse after the opposite…

Optocouplers for AC & DC
Optocouplers are used mostly in power electronics circuits to isolate the fatal mains utility voltage to that of the low dc voltage that the control circuit works. Therefore some call it optoisolators. They find use in control circuits feeding Thyristors,MOSFETs,IGBTs. Submitted below an audio visual for better understanding.
