A tutorial on how to make an LED roulette circuit using 555 timer & 4017 IC on a breadboard. This circuit replicates the functioning of circular roulette wheel. Circuit diagram, detailed steps to build this circuit and an explanation of its working is also included.
A tutorial on How to make a DC Voltage Doubler Circuit on breadboard using 555 Timer, Diodes & Capacitors. This circuit takes in a DC voltage anywhere between 5V to 15V and produces double the input voltage at the output.
In this tutorial we'll learn how to make a light sensor circuit using LDR (Light Dependent Resistor), 555 timer IC and a few other electronics components. This circuit detects light incident on the LDR and turns on LED whenever the intensity of light is greater than a certain level.
