What do you do with 144 7-segment displays ... This presented a problem, as [Frugha] wanted to control the clock with a single Arduino Nano. Even charlieplexing won’t get you that many I ...

Reddit user Krukerfluk has created an awesome DIY digital clock using 144 x seven segment displays, combining them to create a larger LED display powered by an Arduino Nano. The small Arduino ...

Maker Michael Klements has built a unique electromechanical clock using a little Arduino hardware, code, and 28 servos, which tilt panels to reveal the correct time in digital format. As the time ...

His clever solution is to use an Arduino Uno R4 and take advantage of the onboard DAC. To turn on a segment, he connects a segment to a GPIO pin set high while sending 3.5 volts out of the DAC ...

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 ...

With the integration of the RA4M1 processor from Renesas, the UNO R4 adds a 32-bit microcontroller with up to 16x the clock speed, memory and flash storage. Based on an Arm Cortex-M4 core, the RA4M1 ...
