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 ...
It means for an Arduino Uno trying to update a TFT such as an ILI9431 - it is probably going to struggle with the amount of data output to the screen and will probably lag.The larger display is going to need a faster and more memory fueled processor such as a DSP e.g. DSPIC32 ...

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...

I had this little project in mind but after chewing on it for a while I figured that to achieve my goal I would need more pins than the Arduino Uno can offer. I started looking at what my options were and soon I found something that looked very promising – shift registers (yes, I ...
