VCC goes to arduino +5v GND goes to arduino GND DIO goes to arduino D4 CLK goes to arduino D3 To add additionnal modules simply select free pins in the arduino setup tool Note : On some TM1637 models ...

I see that not all TM1637 display boards have the same connector, you might need to switch the order of some of the pins, or move them from the top right corner of the PCB, towards the D pad buttons, ...

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 ...

I needed a tacho/RPM display for a CNC spindle. I decided to use an Arduino Micro and OLED display with a reflective LED/Photo transistor as a sensor. Since powering up, a clock can display the total ...
