The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close ... receiver IR1 is only ...

Step-by-step guide on designing and programming a custom I2C slave sensor device using Arduino. Trump overpowers Musk's ...

set out to reduce or eliminate the barriers that keep many people from jumping into Arduino. One phototransistor to detect infrared and visible light An I2C digital temperature sensor to introduce ...

the sensor will detect a drop in light intensity and subsequently activate the buzzer. The alarm only stops when you press the push button connected to the Arduino. For this setup, the program ...

Because his blinkenlight shield can be used as a light sensor, all that’s needed is a mirror and a pretty long line of sight. There’s a few problems with the setup though: with the Arduino ...

Our traffic light sensor has four pins ... This is one of the benefits of Arduino: once you program the microcontroller, it can run a program independently of a host computer.

In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

Most ambient lights and sensors are designed to generate light to even out the picture on the front of the panel and reduce any light bleed from the back of an LCD display. This Arduino-powered ...
