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 I2C LCD: Make Your Own Custom Character

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 I2C LCD Module Display

Overview In this blog we will learn how to use and control a DC motor, by using a transistor, and diode. We will also use a potentiometer to control the speed of the motor. Please click here to learn how to use a potentiometer. Components needed DC motor Transistor Diode Resistor Potentiometer Jumper cables Arduino … Continue reading DC 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 Servo Motor

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 Shift Register controlling brightness

Components needed Ultrasonic Sensor Piezo(buzzer) An LED A resistor Jumper cables Breadboard Arduino Board A computer with the Arduino IDE installed Completed Circuit The image above is the completed circuit for the security system. We will build a simple security system using an ultrasonic sensor where if something is stolen, the piezo (buzzer) will buzz … Continue reading Security System using an Ultrasonic Sensor HC-SR04
