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 ...

In this post I will show how to connect and drive 4-Digit 7-Segment LED Display with Ardino UNO. Recently I have posted a topic on how to drive a single 7-segment LED Display. I think it was simple, but it requires lots of wires. Usually we need to display numbers that consist of...
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 To control the MAX7219 displ...
