In the Arduino board, digital outputs from D2 to D8 are used to drive segments (a to g), and digital outputs D9 to D12 are used for the digits (D0-D3) of the 4×7 LED display. Note that here the ...

Untangling Timer 4 on the ATmega32U4 Timer4 on the ATmega32U4 (Arduino Leonardo, Micro, Pro Micro) is another one of Microchip/Atmel’s high-speed timers that can be fed by a PLL (phase-locked-loop) ...

If you are trying to make sense of high-speed Timer 4 on Microchip’s (Atmel’s) ATmega 32U4, someone called dmm47 has put a useful little resource onto the Arduino forum. At the very minimum, it saves ...

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.

[Hlesliebole] wanted a finer degree of remote control over his time-lapse shots, so he decided to build an Arduino-driven infrared shutter. He ended up creating this killer Arduino-controlled photo… ...

[ZHut] managed to bring these two worlds together by presenting how to make an Arduino blink an LED in conjunction with a 555 timer ... Kirk to compute every digit of pi.
