In this lesson we learn how to use LCD1602 and LCD2004 with Arduino. We first introduce the LCD module, then we look at characters that you can dispaly, then I we learn how to make our own custom characters. Then we learn how to make a simple counter. Using DHT11 we dispaly temperature and humidity on LCD. We measure DC voltage and display it on the LCD using potentiometer. Lastly we use HC-SR04 Ultrasonic Sensor we measure the distance and display it on the screen. Full library installation is shown, all codes are explained and wiring diagram for every project is shown and wiring is done.
