“Arduino Self-Timer” project presented here is a low-component count 60 seconds countdown timer. It can be powered from a 9V compact battery or suitable Arduino AC mains adaptor. Working of the ...

You can use a microcontroller to build a clock. After all, a clock is just something that counts the passage of time. The ...

An Arduino timer answer, probably I have been trying to work out how to use the the timers within 8bit AVR processors through the Arduino IDE, but in modes not covered by the IDE. Lots of people have ...

The programmable timer features and up counter, down counter, and point accumulator that can be programmed manually using only one on-board button, or digitally with your Arduino or Raspberry Pi.

AnalogWrite uses the various timers on an Arduino to put out a pwm waveform – with 1/256 (ish) resolution. And it offers 0% and 100%. This is naturally-available with the timers that the Arduino IDE ...

Droplet and StackAR, developed by MIT’s Media Lab, allow users to set timers or program an Arduino using light-based communication. By pressing the tool against a screen, flashes of light can ...

You have a timer and clock in just about every single device out there these days, but if you want to build you own, Instructables user GeraldF6 shows you how to do so with a Arduino.

Also, this module focuses on how to time events using Arduino’s built-in function millis (). It is designed to be used with a pre-built ramp that can be provided if used in a classroom environment.

To that end, [Josh] wanted to try using a rather famous IC with his Arduino to build a viable timepiece. [Josh]’s idea was straightforward—employ a 555 timer IC to generate a square wave at 1 Hz.

Arduino enthusiasts and makers looking for a project to keep them busy over the next couple of weekends might be interested in this Arduino flying start lap timer, which has been featured over on ...
