A tutorial on how to make a Tap On Tap Off piezoelectric knock sensor circuit using 555 timer IC on a breadboard. This circuit toggles (flip-flops) the output each time we tap on the Piezo-Electric speaker.
A tutorial on how to make a touch sensor alarm circuit using 555 timer IC on a breadboard.
A tutorial on how to make a Touch On and Touch Off sensor switch using 555 timer IC on a breadboard. This circuit uses two pairs of touch conductors to sense and register the touch. One pair of touch conductors (sensors) for turning ON the output and the other pair for turning OFF the output.
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.
