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 ...

[Daniel] created an Arduino Sensor Shield to interface ... to talk to the graphical programming environment. The shield includes resistance sensing, a light sensor, a sound sensor, and a sliding ...

you need to program Arduino to read a sensor and direct the data to the Serial Port. Here, a standard light-dependent resistor (LDR) is used as an analog input sensor and directs its output to the ...
