A push button counter is a simple and useful embedded systems project that demonstrates how a microcontroller can detect user input and perform counting operations. In this project, a push button is ...

to increase a counter value and display it on a 16x2 LCD using an I2C module. Each time the button is pressed, the counter increases by 1 and the updated value appears on the LCD screen.

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 ...
