Features: Hardware components: Arduino, relay module, jumper wires, and external power source Code: Arduino code for controlling the relay based on sensor input or a manual switch Applications: Home ...

The Arduino Relay Shield allows your Arduino driving high power loads. The Arduino Relay Shield allows your Arduino driving high power loads. The Shield features three relays, each relay provides 2 ...

You have to pull an extra wire from the sensor’s input voltage to your Arduino’s AREF pin, so you know what the actual voltage at the end of the cable is, so you can estimate the 10-90% range.

Power output on the banana socket is feed through a relay, so Arduino detaches the output power sensing an external pushbutton or on alarm events (short circuit/under voltage, over-load, over ...

All we need to do is swipe or place an authorized RFID card in front of the RFID reader. Here, Arduino handles data processing activities to decide whether the RFID card is valid or not. If the card ...
