Summary

This circuit is designed to activate a solenoid using an IR remote control. When the '1' button on the remote is pressed, the Arduino 101 microcontroller activates a relay, which in turn powers the solenoid. The circuit includes an IR receiver to capture signals from the remote, a 12V battery to power the solenoid and relay, and a rocker switch to control the power supply.
