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 u
Time set and time countdown are shown on 6 digits of a 8 digit 7 segment display. Step 2: MAX2719 7 Segment 8 Digit Display Module Thw MAX2719 7 Segment 8 Digit Display Module shows the timer value in the 1st 5 digits and general settings in digits 7 & 8. Digit 6 is always blank...

Keep in mind that there are two kinds of 7-segment displays, common anode and common cathode. If you have a different type then Jimmacle, then this won't work for you. The one that Jimmacle used here is a common anode if the link to the spec sheet is correct. I have two differe...

not be able to supply enough current. I decided to replace the 5V regulator with a pin-compatible 3.3V one. The LED drivers are able to operate at that voltage, the 7-segment displays were just fine, the only change I needed to make was to bring the ATmega328 down from 16MHz to 8...
Inside the juicy enclosure is an Arduino Nano, an RTC, and a 7-segment display. We love the attention to detail here, from the little green leaves on top to the anatomically-correct dimple on the underside. And we always like to see lids that snap on with magnets. So satisfying. Check...
