What do you do with 144 7-segment displays? If you’re [Frugha] you put them all together to create an epic clock. Each display has 8 individual LEDs — 7 segments, and a decimal point. P… ...

His clever solution is to use an Arduino Uno R4 and take advantage of the onboard DAC. ... Posted in clock hacks, LED Hacks Tagged 7 segment, clock, ESP8266, IMU, led matrix, ...

“I’ve built a digital clock made out of 144 seven-segment displays controlled by an Arduino Nano. The segments are controlled by 18 MAX7219 ICs which can control up to 64 individual LEDs or 8 ...

The heart of the clock is the Arduino Uno, a versatile microcontroller known for its ease of use and flexibility. The Arduino Uno reads the time from a DS1302 real-time clock (RTC) module.

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 ...
