A Better Arduino Color Sensor using TCS230

Last time, I showed how easy it is to detect colors using the Pixy2 camera. However, the camera’s price might be too expensive for some. Luckily, there is a much cheaper option to implement an Arduino color sensor. The color sensor I’m referring to is the TCS230 (and equivalent TCS3200) …

Use LM393 IR Module as Motor Speed Sensor

Unlike stepper and servo motors, precision control for DC motors is impossible unless a sort of feedback mechanism is employed. If your application requires a consistent motor speed or a stimulant-dependent speed then you certainly need feedback. This tutorial aims to develop a simple motor speed sensor for a more …

Building an Arduino Water Flow Meter

How do you measure the volume of a liquid? There are a couple or so ways to do it. One technique is by determining the level of the liquid in a container with a known cross-sectional area. For level measurements, an ultrasonic sensor is useful. Another technique is to use …
