This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to ... For testing purpose only one 330 Ohm resistor (R2) is added between ...

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 ...

things: addressable seven-segment LED displays ... Like many of [Sean]’s designs, including this Arduino rapid design board, this is a simple way to get a tedious job done, and it wrings ...

The solution to this problem was to use a shift register and control multiple segment displays with an 8 pin microcontroller. [volts] is using an ATtiny13 to control six seven segment displays.
