Introduction Timers are one of the most important features in embedded systems because they allow microcontrollers to perform tasks at precise intervals without constant CPU intervention. In this microcontroller project, we demonstrate how to use the Timer module of the Raspberry Pi Pico using MicroPython inside a Proteus simulation environment. This project is a simple […]

After receiving one IN-8 tube from a friend (thanks), I decided to build myself a clock. This clock is more an ornament than a useful machine because it consists of just one digit (tube) so it displays current time every minute for three times. It is built inside of an old wooden box and it’s

Description : The purpose of this timer is to provide a countdown time from 1 second to 99 minutes & 59 seconds. I use it to control the lighting for the Ultra-Violet exposure of photosensitive PCB material. The project provides also an audible alarm at the end of the countdown time and switches the UV

The goal of this project is to construct a simple 0-9999 seconds count down timer with an alarm and a display. The time is set through two tact switches and the count down seconds are displayed on a 4-digit seven segment LED display. The project uses PIC12F683 microcontroller for all I/O and timing operations and
