Welcome to part three of “Interrupts: The Good, the Bad, and the Ugly”. We’ve already professed our love for interrupts, showing how they are useful for solving multiple common microcontroller tasks ...

OK, year-old pop culture references aside [Kyle] dropped us a line to show us his tutorial on using interrupts with your Arduino. Given the single core nature of your average Arduino’s AVR you pretty ...

Stepper motors are mostly used for precise motion control of structures or axes for a distance. But what happens if we want to control time? We can answer this question with the bare motor rotation, ...

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 ...

“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 ...

We’ve featured a lot of interesting DIY timepieces in the past (most recently this Arduino Sesame Street creation) and the community keeps on creating new ones. Andy Evans, who goes by the username ...

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 ...

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.
