“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 ...

Today we are going to create a strobe light for the tips of the wings of an rc airplane using a 555 timer (NE 555 or lm 555 IC) this circuit is very easy to make with few components and most ...

Runner and Arduino enthusiast Nikodem Bartnik has created a DIY 100m sprint timer which is placed at the finish line and signals the start of timing via an audible bleep from its integrated speaker.

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 the ...

I have been delving (groping blindfold, more accurately) into the Arduino compiler adaptation code to try to determine how it handles the switch-over between its pwm activities, its set-I/O-to-output ...

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 put up code, often two or three ...

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 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 ...
