Think about the famous 555 timer chip or dual-operational amplifiers such as the LM358. You can also find comparators (LM393) and audio amplifiers (LM386). You can put two optocouplers (PC817) into the socket. Some microcontrollers such as the ATtiny85, PIC12F1840, or PICAXE-08M2 also ...
The main intention of this project is to design a remote jamming device, which can jam the TV remote rays. In this system, infrared rays develop – they are generally emitted by a TV remote. The proposed system is built by using a 555 timer in astable mode, which is made to generate ...
This project is mainly used to implement a tester circuit that is used to test different cables and wires. This circuit uses a decade counter and a 555 timer IC. Microcontroller based Celsius Scale Thermometer The main function of this project is to measure the surrounding temperature over the ...
