NE555

The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide two (556) or four (558) timing circuits in one package. Introduced in 1972 by Signetics, the 555 is still in widespread use due to its low price, ease of use, and stability. It is now made by many companies in the original bipolar and in low-power CMOS technologies. As of 2003, it was estimated that 1 billion units were manufactured every year. The 555 is the most popular integrated circuit ever manufactured.

RF Listener

“So what is this thing? Basically it’s a handheld device that allows you to “hear” RF sources. Regular rf receivers single out a particular frequency and decode it into some type of information. This device on the other hand …

Automatic Water Level Controller for Pump using 555 Timer IC

“Automatic water level controller for the submersible pump and overhead tank with 555 timer IC. Also check the underground tank water level. In this mini electronics project, I have shown how to make an automatic water level controller for the …

Simple AM Radio Transmitter & Receiver

“In this project we will keep it simple when it comes to wireless audio communication. Instead of trying to use an nRF24 or RF modules, we will go back to the old days in which they used AM radios. I …

LED Running Lights

“In todays article, I will show you running lights based on three popular microcircuits: an operational amplifier microcircuit LM358, a timer microcircuit NE555, and decimal counter microcircuit CD4017. The running lights schematic diagram and printed circuit board (PCB) were developed …

555 Fizzle Loop Synth V4

“I’ve hit a pretty significant milestone with this Instructable - my 200th! It’s been a busy 9 years, building and learning a lot of new skills whist producing these 200 ‘ibles - and it’s been a blast. Thanks to …

Adjustable High DC Voltage Generator

“This project is about building an adjustable high voltage generator (DC) from a low DC voltage supply. The voltage supply can range from 5V to over 25V (I use a 9V supply). Higher voltages can require heat dissipators attached to …

My Daughter’s laptop

“It’s a programable “laptop”. Hardware that allows me to program different activities in a nice box This is a long project, I will divide it into small bits so people can take pieces and set up their own. I …
