NOW, IT IS POSSIBLE TO CONNECT A RELAY MODULE TO THIS KIT TO OPERATE APPLIANCES WORKING AT 100-240V AC. It's simple DIY clap switch for electronics beginners and amateurs. The circuit operates in two permanent states- ON and OFF. On the first clap, it switches on the LED and on the second clap, it switches off. This circuit can be a good start for amateurs. Comes as a pack of parts kit and is 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 6V-9V battery. Kit package contains the following components: 2 x 4.7K resistor 1 x 470R resistor 3 x 2.2K resistor 1 x 470K resistor 1 x 1K resistor 1 x 47K resistor 5 x 10K resistor 2 x 1N4148 diode 4 x 9013 Transistor 1 x LED 3 x 0.1uF ceramic capacitor (code 104) 1 x 0.01uF ceramic capacitor (code 103) 1 x 47uF electrolytic capacitor 1 x 1uF electrolytic capacitor 1 x Electret microphone. 1 x Bare PCB with Silkscreen Indicators 1 x JST connector for power supply We may send 4 color or 5 color code resistors.
