A delay before turn off circuit can be useful for any circuit that needs to be on only for a short period of time, such as a timer. Say you want a circuit to only be on for 10 seconds and then stop. Then this circuit has perfect application. How we achieve the delay effect is th...
The 555 timer chip is a very versatile IC, because when connected correctly, it can it can create pulses of current at specific time intervals decided by the resistor-capacitor (RC) network. When a 555 timer creates pulses in this way, the LED doesn't stay constantly on. It only turns ...
I have explained comprehensively how to build a boost converter circuit for converting a low level DC voltage inputs to a higher level DC voltage outputs. I have furnished all the required calculations s that you can design a customized boost converter circuit. Contentshide 1How a Boost Converte...
In this tutorial, you’ll learn how to build an automatic night light circuit that turns on when it gets dark. It’s a simple circuit that you can build on a breadboard. This circuit shows you how to do it with an LED. But you can use the same principle to turn on bigger and bri...
Our first example is how to blink an LED with the 555 Timer. This is like the “hello world” equivalent of this IC. Component List This circuit is simple enough to build on abreadboard. To build it, you need the following components: ...
Steps to Build a Wire Loop Game To build your own wire loop game project, you need batteries and wires. In this game, players won’t get shocked if they lose. Instead, a buzzer will generate a sound whenever the metal loop touches the curved wire. This game has two challenges, In cha...
In conclusion, the simple music box circuit is a fun and easy-to-build project. This circuit is a great way to explore the world of electronics and music. We hope you enjoyed learning about this circuit and feel inspired to try building it yourself. With just a few components and some ...
How to Build a Boost Converter In this project we build a 1.5V to 5V DC-DC Boost converter. Here are the components that you need if you want to build this circuit: 1.5V DC power source One 180uH inductor One 1N3491 diode One 33uF capacitor ...
So I want to generate a pulse (high) of 2 seconds when that DC supply is turned ON. I know we can do this using timer ICs like 555 timer, or any microcontroller, or using gates (but this uses IC, RC components etc,) but I was wondering if I can m...
Advances in technology mean that it is easier than ever to build an LED flasher. It is also possible to control the amount of time the light remains on as well as the frequency of its flashes. The flasher circuit can be made with a standard 555-timer chip. Other items that are required...
