“In this guide I will show you how to make your own Arduino learning shield. This learning shield can be useful at schools, universities and to everyone that want to start dealing with the Arduino. With this shield you will learn how to read the temperature and humidity from DHT-22 sensor, read an object distance by using the HC-SR04 ultrasonic sensor, print sensor values to the NOKIA 5110 LCD. On this PCB board you will also find three LEDs, two buttons, buzzer, trimmer and photocell sensor!
Bellow you will find the PCB layout so you can easily produce it.”
