He dragged the component onto the schematic. The difference was immediate. What used to take forty wires now took twelve. He wired the inputs to PORTB of his PIC microcontroller, connected the VCC to 5V, and grounded the GND. He connected four LEDs to the NO (Normally Open) terminals of the relays.
"It would be," Omar grumbled, clicking the 'Play' button on Proteus for the twentieth time. "If I didn't have to wire twenty individual transistors just to simulate the relay logic. Proteus keeps crashing because the netlist is too messy." --- 4 Channel Relay Module Library For Proteus
A standard 4-channel relay module allows independent control of four separate high-power circuits. He dragged the component onto the schematic
Whether you’re designing a smart home system, an industrial controller, or just learning relay logic, adding this module to your Proteus toolkit is a smart move. He wired the inputs to PORTB of his
