This unipolar stepper motor driver circuit is used to drive a 12V unipolar stepper motor with a current rating of 1.25A. It uses PCA9537 IC, which is a 10-pin CMOS device that provides 4 bits of General Purpose I/O (GPIO) expansion with interrupt and reset for I2C-bus/SMBus applications. It consists of a 4-bit configuration register […]

Step 1: Understanding the circuit The circuit is really easy to understand. A resistor of low value (the resistor value will be explained later) is connected in series with the output of the power supply. As current starts to flow through it, a small voltage drop will appear on it and we will use this

Why op amps are important Op amps are a key component in analog circuits. An op amp takes two input voltages, subtracts them, multiplies the difference by a huge value (100,000 or more), and outputs the result as a voltage. If you’ve studied analog circuits, op amps will be familiar to you, but otherwise this
