To add additionnal modules simply select free pins in the arduino setup tool Note : On some TM1637 models clk or dio pin (never both at the same time) can be shared across multiple modules. If you ...

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 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 ...

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 ...
