IR Remote Switch v2
This circuit is live in Circuit Canvas. Open it to explore every part and wire, or make your own copy to change values, swap parts and build your own version. Free, right in your browser.
This project shows you how to create a simple remote-controlled on-off switch that will work with most IR remote controls. And you only need four components to build it—an IR receiver, a capacitor, a JK flip-flop, and a relay module.
You can connect whatever you want to control to the relay, and then use any IR remote control to turn it on or off.
IR Remote Switch v2 Schematic
Push a button on the remote control and it will send out a signal consisting of many pulses. This is then received by the IR receiver and converted into one long pulse. This long pulse will toggle the flip-flop.
The flip-flop controls a relay module. Every time you press a button on your remote, the relay turns on or off.

How to Build the IR Remote Switch v2
You can connect the circuit on a breadboard as shown below to test it out. Then later, solder it onto a stripboard to make it permanent.
Make it your own
Every circuit here is a live project in Circuit Canvas, not just a picture. Copy this one and change a value, swap a part or move it to a stripboard: the schematic and the breadboard layout are linked, so a part added to one appears in the other.
Or start from a blank canvas and draw your own circuit, with thousands of ready-made parts.
