The idea of this electronic queuing system is to display both sequence number and counter number in three seven segment displays. For example, when counter 1 presses his button, the number 1 shows up on the counter number segment. At the same time, the sequence number is incremented. This system …

This project is basically a remote-controlled car that is controllable via an application installed on a Bluetooth-equipped smartphone. Here's my version of a Bluetooth RC Car.

Project Overview I was recently commissioned to create a simple project for a coffee roasting machine. Basically, I need to measure the temperature of the machine in real time to monitor the progress of the roasting process. This includes a line graph that updates every second and is viewable on …

Project Overview This adjustable timer displays seconds, minutes, and hours and is powered by a PIC16F 877A microcontroller. There are five buttons included: start/stop, up for incrementing digits, down for decrementing digits, and left and right for moving between digits during adjustment. I’ve included a relay circuit that will trigger …

The Nokia 3310 LCD is a cheap option for those who want to add a graphical display to their microcontroller projects. This digital thermometer project uses this LCD to display the temperature from a LM35 temperature sensor.

This project is a stepper motor controller featuring the PIC16F877A microcontroller and coded using XC8. The controller has three control buttons: start, stop, forward and reverse. The project was created with a six-wire unipolar stepper motor in mind but may work with other stepper motors with some modifications.
