This breadboarded circuit is [Sergio’s] option to controlling appliances wirelessly. particularly he desired a method to turn his pool pump on as well as off from inside the house. considering that he had a lot of of the parts on hand he made a decision to develop a option himself. What he ended up with is an RF base station that can discover to take commands from different remote devices.
The primary elements include the solid specify relay at the bottom of the image. This lets the ATtiny13 switch mains voltage appliances. The microcontroller (on the copper clad square at the center of the breadboard) interfaces with the eco-friendly radio frequency board to its left. On the ideal is a single leaf switch. This acts as the input. A quick click will toggle the relay, however a three-second press puts the gadget in discovering mode. [Sergio] can then press a button on an RF remote as well as the gadget will store the got code in EEPROM. As you can see in the clip after the break, he even included a method to fail to remember a remote code.
