[Hlesliebole] wired a 7-segment display to show the current time delay between photos. This can be set on the fly with a potentiometer, so there’s no need to stop and reprogram the Arduino.

Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced circuits using multiple seven-segment light emitting diode displays. Here is a simple, yet useful ...

His clever solution is to use an Arduino Uno R4 and take advantage of the onboard DAC. To turn on a segment ... This isn’t the first time we’ve seen [upir] trying to jazz things up in the ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

Electronics designer Patrick Thomas Mitchell has returned once again to Kickstarter to launch his new Raspberry Pi and Arduino programmable timer aptly named the Ninja Counter. The programmable ...

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 ...

a time-of-flight distance sensor, a buzzer, a thermometer and humidity sensor, and a set of three buttons. To help keep things organized, all of the components, including the Arduino, can be ...
