(Original design by Sagar Sapkota)
This is a simple 4-in-1 do-it-yourself (DIY) kit from BuildCircuit. The kit has four different circuits that can be switched on separately or together at a time using a DIP switch.
The four circuits are:
Besides these 4 circuits, by changing the values of the resistors and capacitors, you can change the behavior of the circuits. For example, in the astable circuit, if you change the resistance values, it works as an Infrared (IR) transmitter and you can use it in remote operated switch circuits.
