Overview : This projecr implements a car speed detector using an Arduino microcontroller and an IR sensor. The system measures the speed of passing evhicles by detecting interruptions in the infrared ...

What do you need to build an Arduino Speed Sensor. Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, and it is also very ...

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

Tachometer is a RPM counter which counts the no. of rotations per minute.There are two types of tachometer - one is mechanical and the other one is digital. Here we are going to design an Arduino ...
