This Arduino project shows how to read analog voltages from analog channel and print the digital values on 7-segment display. A potentiometer is used to get a voltage that varies between 0 and 5V. A common anode 7-segment display is
This post shows how to interface Arduino UNO board with 7-segment display in order to build a simple 4-digit counter which counts from 0 to 9999. A push button connected to Arduino is used to increment the displayed number. There

This post shows how interface Arduino UNO board with Nokia 5110 (3310) graphical LCD screen. The name Nokia 5110 (3310) comes from Nokia 5110 (or Nokia 3310) mobile phone. The Nokia 5110 LCD has a controller named PCD8544, it is
This post shows how to control stepper motor speed and direction of rotation using Arduino UNO board and PS2 joystick. The stepper motor used in this example is 28BYJ-48 (unipolar stepper motor) which usually comes with its driver board. In the last

In the last Arduino project, I made a simple motor controller which controls the speed and direction of rotation of CD-ROM bipolar stepper motor. Now I’m going to show how to do the same thing with uinpolar stepper motor. The
This small post shows how to control speed and direction of rotation of bipolar stepper motor using Arduino UNO board and L293D motor driver chip. The stepper motor used in this example is just a PC CD-ROM (or DVD-ROM) drive
This Arduino project shows how to build a GPS clock with local time adjustment (UTC time + offset) using Arduino UNO board and NEO-6M GPS module. Time and date are displayed on 20×4 LCD screen. In this project the Arduino
