This is a simple do-it-yourself (DIY) remote operated switch. You can use this simple kit to turn ON/OFF a pair of LEDs.

This has been designed basically as a learning kit. With this kit, you may learn about TSOP4838 infrared sensor and CD4017 versatile IC.

This DIY remote operated switch works with TSOP4838 infrared receiver. To make the kit work, you just need a general TV/DVD remote or you can also build your own IR transmitter. Transmit infrared signals to the sensor and the kit will turn on/off LEDs.

The maximum distance between the kit and IR remote can be around 3 meters. Once you switch it on, one LED remains on until you press your remote again, which means that there are two stable states (ON and OFF).

When one LED is ON, the other is off and vice versa.

It comes as a pack of parts kit and can be easily assembled if you can follow the silkscreen indicators (labels) and have beginning experience with a soldering iron. You will need to read the resistor bands or use a multimeter to determine the resistor sizes.

The kit operates with a 6-9V power supply.

Features:

  • The distance between the IR transmitter(TV/DVD remote) and receiver kit can be around 3 meters.
  • The kit can be operated with any kind of remote control. Therefore, it can also be used as a remote tester.
