Using Electronic Sensors in Arduino

The world of sensors is a wide, wild one. In this introductory lesson, learn which sensors you'll be using in this Arduino course, from photo to ultrasonic.

In this second lesson of a series from Dr. Peter Dalmaris, learn how to detect and measure light using a photoresistor, and how to use a voltage divider.

Who needs a thermometer when you can measure temperature and humidity with a few DHT sensors and your handy Arduino setup and sketch? Learn how in this lesson!

Meteorologists use it to read weather patterns and geologists to determine altitude: a barometric pressure sensor, a sensor that measures atmospheric pressure.

Motion sensors are used every day: for security purposes or to turn lights on and off. Learn about motion sensors and how to put your own PIR to work!
