The circuit was designed to produce a digital roulette that will display the result using a 7-segment LED display. Roulette – refers to a game of chance played at a table where a small ball is made to ...

A display decoder is used to convert a BCD or a binary code into a 7 segment code used to operate a 7 segment LED display. Here we design a simple display decoder circuit using logic gates. A display ...

LED (Light Emitting Diode) An LED is a semiconductor device that emits light when current flows through it. LEDs are commonly used in electronics to indicate status or provide visual feedback.

[Hales] has been on a mission for a while to make his own diodes and put them to use and now he’s succeeded with diodes made of sodium bicarbonate and water, aluminum tape and soldered copper. By ...

Output devices such as motors, solenoids, bulbs, buzzers, relays, LEDs, and 7-segment displays are used in many electronic circuits. Circuit diagrams illustrate how these devices are connected and ...
