Tutorial 15: I2C LCD- Custom Character
In this tutorial, we will learn how to make custom characters on an I2C LCD display. Click here to refer to my previous blog and learn about the I2C LCD display basics. Custom characters are non-original figures created from original parts. You can create different figures such as hearts, squares, rectangles, and more. The I2C … Continue reading Tutorial 15: I2C LCD- Custom Character
Tutorial 14: I2C LCD
LCDs are fun and we can use them in Arduino projects to show status messages or to display information like temperature or distance or any value instead of showing them in the serial monitor. In this tutorial we will learn how to connect 16x2 character LCD to Arduino board and how to display information on … Continue reading Tutorial 14: I2C LCD
Tutorial 13: DC Motor

Tutorial 12: Servo Motor
What is a servo motor? The servo motor is a special motor that you can rotate with a precision. It can be used to build remote control toys, etc. It is built in with several parts like a control circuit, servo motor, shaft, potentiometer, drive gears, an amplifier, and an encoder. The output shaft of … Continue reading Tutorial 12: Servo Motor
Tutorial 11: Shift Register controlling brightness
In my earlier blog, we learned about the 74HC595 shift register. In that blog we learned to connect LEDs to all output pins of shift register. As we know that all those connected LEDs had full brightness. In this blog, we will learn how to control the brightness of those LEDs. To control the brightness … Continue reading Tutorial 11: Shift Register controlling brightness
