Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

Count-up timer with call specified method when count is complete. Count-down timer with call specified method when count is complete. Calling any method at a specified time interval. It allows you to ...

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 ...

Walking safely and confidently can be a challenging task for visually impaired individuals, but with the help of technology, we can make it easier for them. This DIY Blind Stick is an innovative yet ...

Abstract: This paper presents a new AnalogTimer circuit which is used to design A stable and Monostable multivibrators. The circuit employs comparators designed using OTRA and and flip flops ...

This article is part of the 2022 April 1st series in the Humor topic within our Series Library. The ubiquitous 1971 digital miracle—the 555 Timer—is important, replete with 25 transistors, 15 ...

Manual -> It starts a Pomodoro or a break with the button. Auto-loop -> It starts a Pomodoro or a break automatically (to reset it is necessary to pause).

Abstract: The 555 timer IC is a well-known integrated circuit having been widely used as a pulse generator. We propose a circuit containing a single 555 IC, an LED, an inductor, two capacitors, and ...

Electronics designer Patrick Thomas Mitchell has returned once again to Kickstarter to launch his new Raspberry Pi and Arduino programmable timer aptly named the Ninja Counter. The programmable timer ...

A switch is the most essential part of any circuit. Different circuits use different switches in them. In this project, we are going to use a Touch Dimmer Switch. This switch is a touch-sensitive ...
