Analog Speedometer Using Arduino and IR Sensor

Measuring the speed/rpm of a Vehicle or a motor has always been a fascinating project to try. In this project, we are going to build a Analog Speedometer using the Arduino. We will use IR Sensor module to measure the speed. There are other ways/sensors for this, like hall sensor to measure speed, but using an IR …

Arduino – Using a Sharp IR Sensor for Distance Calculation

Well, looks like my sonar sensor (SRF05) is a just a tad inaccurate for precise measurement as I found from my radar screen I made (Arduino Radar Sscreen). So I’ve got hold of a Sharp GP2Y0A02 series infrared distance sensor. It’ll detect and measure anything within a 20-150cm range and it does this by triangulation …
