Example: At indoor light the sensor will give a value of around “750” when using the “analogRead” function while using Arduino it’s around “3.66V” (1023 for 5V), but when you cover the sensor it will ...

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 ...

Here is an ultra simple Arduino Night Alarm project wired around a handful of inexpensive and easily available components. One advantage of using Arduino as a security system is the flexibility!
