Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-cathode module containing four 7-segment LED numeric ...

The other thing is, I happen to have an Arduino Micro on the desk next to me (and a Pro Micro, but it omits an important PWM pin: /OC4A or /OC4D). BTW, Adafruit’s Feather 32U4 Basic (3.3V 8MHz) and ...

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 ...

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 ...

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. The project ...

[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 ...

[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.
