Arduino Light Sensor Tutorial

Arduino Light Sensor Tutorial

In this Arduino light sensor tutorial we’re going to show the basics of connecting a light sensor (or photoresistor) to the Arduino and reading its input. A photoresistor is a sensor that changes resistance based on the amount of light being delivered to its sensor. In this way we not only detect whether it is […]

Control High Voltage Devices with an Arduino

One of the best features of the Arduino is the ability to control relays.  Relays allow a circuit of one voltage or current to be operated by a circuit of a different voltage or current. In the case of an Arduino that operates at either 3.3V or 5V DC, connecting a relay allows us to […]
