The function of the 555 timer is mainly determined by two comparators. The output voltage of the them controls the state of the RS flip-flop and the discharge tube. It also contains 3 working states.

Chris Gammell from the blog The amp hour and Analog Life is running a 555 timer IC design contest. EDN’s Mike Demler wrote it up on his blog yesterday. So Mike or Chris asked me to do a mention on ...

Part of Design and Technology Electronic and microelectronic control systems The 555 timer is a versatile integrated circuit (IC) that can control timing in electronic circuits. It's one of the most ...

This voltage-booster circuit for driving one or more white LEDs uses a 555 timer as its main element (see the figure). The timer, IC1, functions as a resettable astable multivibrator where R1, R2, and ...

You can use a microcontroller to build a clock. After all, a clock is just something that counts the passage of time. The only problem is that microcontrollers can’t track time very accurately. They ...

Hans Camenzind, the designer of the popular 555 timer IC died this week in Silicon Valley. He was 78. My condolences to his family and friends. Hans came to the U.S. from Switzerland in 1960. He ...
