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.

DIY Simple Sensitive IB Metal Detector with 2xNE555 IC

“A relatively sensitive IB (Induction balance) Metal Detector which is very easy to make, and contains a few standard electronic components In the previous period, I presented several types of metal detectors that were based on microcontrollers and Android smartphone …

BreadBin computer

“After various experiments and failed attempts to design a 7400-based computer, I came to a quite minimalistic 8-bit approach which is nevertheless pretty versatile and can utilize a surprisingly large amount of memory resources. The CPU core itself executes its …

Dub Siren V3 - 555 Project

“Ok - so this is going to be my last dub siren build (maybe…). This new one is an extension on the others that I have built and is definitely the best and easiest version I have designed. So what is …

Electronic Ghost

“This spooky electronic ghost is a 555 LED flasher circuit encapsulated in silicone rubber.”

Universal Logic Probe

“These days good quality oscilloscope is not an expensive instrument and, we can see it in most workbenches. With the advancement of oscilloscopes, simple testing tools such as logic probes are not as popular these days. However, if the oscilloscope …

Humidity Sensor – Humidity to Frequency Output

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 …
