In the cluttered workshop of a young engineer named Leo, a tiny blue box sat atop a breadboard. This was no ordinary component; it was a Songle SRD-05VDC-SL-C relay. To most, it was just an electromechanical switch. To Leo, it was the bridge between his low-voltage digital world and the high-voltage hum of his apartment. because it is the standard part for "SRD-05VDC-SL-C"

A yellow wire connected Digital Pin 7 to the relay's trigger. To most, it was just an electromechanical switch

The SRD-05VDC-SL-C is a 5VDC relay module with a single-pole, double-throw (SPDT) configuration. It features a compact design, measuring just 23mm x 15mm x 10mm, making it ideal for space-constrained projects. This relay module can switch loads up to 10A at 250VAC or 30VDC, making it suitable for controlling a variety of devices, from lamps and motors to valves and solenoids.
