I built acountdown timera couple of months ago using a two digit mechanical 7 segment display which was driven by 14 servos and an Arduino Mega. It came out quite well and a number of people suggested doubling up on the display to build a clock. The only problem was that the Arduino ...
Now its time to connect mySMA4205644-digit 7-segment LED display to Arduino UNO. Required components are available inThe Arduino UNO Basic Learning Kit. We need 4 resistors, breadboard and 12 wires. Connect limiting 470 Ohm resistors to 12, 9, 8, 6 PIN of the 4-Digit LED Display. Wires...

The maximum power that the Arduino Uno can safely deliver when powered from USB is around 400 mA at 5 V. If you want to control a large display it is therefore advised to use an external power supply. Installing the MD_Parola and MD_MAX72XX Arduino libraries ...
