Overview This project demonstrates how to control the brightness of an LED using a potentiometer (analog sensor) with an Arduino. The potentiometer’s value is read by the Arduino and mapped to control ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I. ... 0 comments on “ Arduino IR Proximity ...

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 ...

There is only one common solution for this problem: Modulate your IR signal so that your sensor can detect an IR variation rather than a fixed IR level. In this tutorial, we are going to interface E18 ...

This sensor can be used to help a robotic car follow a black line. 1). Adjusting. Place the sensor such that there is 12mm between reflective photosensor and white (or light) colored surface. 2).

In this article, I have added three sensors with Arduino UNO and user can choose the required sensor with the help of keypad. ... I have used the potentiometer to change the resistance value. As the ...

For patients to receive good care, doctors must be present. To administer medication or provide treatment, he can’t be everywhere at once. If we regularly examine our health, we may be able to ...

An infrared sensor based prototype of self-adaptive traffic signal control system has been developed in this paper. An autonomous traffic signal system can be an effective measure to alleviate ...
