If the button is pressed, the green light is turned on and in rest of time, the red led is turned on and the green led is off. Simulation made in Proteus 8 and the PCB Design is made in KiCad ...

Sure, here's a concise summary: The 8x8x8 LED Cube is a decorative piece controlled by an Arduino Uno, capable of displaying various light patterns. It uses a 93dn8wy (SN74HC595N) IC, PN2222A ...

Microcontrollers are one of the best ways for adding digital interconnectivity and ‘smart’ features to a product. However, these microcontrollers are not capable of directly controlling anything other ...

july/august 1984 a power-photo transistor The 2N3055, strange though it may seem, can operate very well as.a photo transistor, as the circuit here shows. The power transistor must be made light ...

There’s many a time when you want to connect a white LED to a microcontroller operating from a 3 V supply voltage. Unfortunately, this doesn’t work and your nice white LED only lights up feebly or not ...

The transistor and the PWM-switch, the core circuit of power converters, have interesting analogs. Both have three terminals, hence three configurations. They are active devices, and each has a key ...
