of the 4×7 LED display. Note that here the decimal point (dp) option is not used, but included in the sketch. D13 of the Arduino is reserved for the decimal point segment. The 10K potentiometer is ...

Another useful component is a potentiometer ... clock using 7-segment displays. Along the way, we experimented with all sorts of things, including light-dependent resistors (LDRs) and ultrasonic ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

Of course, there’s nothing unusual about using 7-segment displays ... a 3D-printed case and an Arduino Nano coupled with a DS1307 make the clock part work. Honestly, with a few changes, we ...
