Analog to digital converter: light measurement

In this tutorial we build a tool that enables you the measure the amount of light. For this we use a phototransistor that is connected to the Dwengo board. You learn how to connect analog sensors to the Dwengo board and how to use the built-in ADC module (Analog to Digital Converter).

Sensors for robotics

Sensors exist in many shapes and forms. This makes it hard to find the right sensors to build, for instance, a robot. In this document, we provide some information on different types of sensors and how to connect them to the Dwengo Board.

Interrupts, driving a servo: a light tracker

In this tutorial we explain step by step how to build a small robot that drives in the direction of the light. For this the robot uses a servo and two light sensors. The same principle could be used to always perfectly align solar panels in order to maximize their performance.
