Wire ground (black wires) to the battery, to the GND pin on the Arduino, and to one of the switch pins on the relay. Wire the positive (red wires) to the battery, to pin 10 on the Arduino, and to the other switch pin on the relay. Wiring can be tricky - even with a basic ...
5V Relay The SunFounder Kit used to include an optocoupler, but that has since been replaced with a 5V relay. A relay is an electromechanical switch that allows you to close and open circuits without mechanical contact. Optocouplers are typically cheaper, more reliable, and faster than a relay...
We will connect LEDs now but they wouldn’t be used in the first code. We will use them in the second one. If you use a different IR receiver, it is possible that you will need to add resistors, you should check the datasheet of the IR receiver. When everything is ready, we can...
