ToyTech Machines on Instagram: "This project demonstrates how to control multiple LEDs using two 6-channel relay modules. With a 6x6 Relay-Controlled LED Matrix, it controls 36 LEDs, lighting up one at a time by activating a specific row and column. The relays switch the positive and negative connections, turning on the LED at the intersection of the active row and column. This project is a great way to explore how relays work, simplify wiring, and showcase the mechanical switching of relays in
