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 ...

Simple Arduino motion sensor using PIR sensor and buzzer. How PIRs Work by lady ada PIR sensors are more complicated than many of the other sensors explained in these tutorials (like photocells, FSRs ...

// Bu projedeki temel hedef arduino kullanarak duman sensörünün çalışma rensibini daha iyi kavrayabilmektir. Duman sensörleri temelde içine giren duman (yangın dumanı, sigara dumanı, su buharı gibi) ...

The circuit of Arduino-based shadow alarm is shown in Fig. 1. It consists of an Arduino board, power supply, light-dependent resistor (LDR) sensor, buzzer, relay driver and a few other components.

In this tutorial, we will build a basic rain sensor using Arduino with a buzzer. You can then use this set-up to build anything you wish on top of it. Also, note that the rain sensor module is also ...
