Until recently, a very common problem faced by electronic circuit designers was the difference in supply voltage standards between microcontrollers (e.g. 3.3 V) and peripheral ICs (e.g. 5 V). In order ...

As mentioned i have a circuit that transmits data through light(VLC) and receives it through phototransistor. The aim is to transfer a file from one PC to another PC hence we used a serial port ...
