Functionality: IR Sensor Detection: The IR sensor is connected to digital pin 7 and is used to detect the presence or absence of an object (e.g., the door). LED Indicator: An LED connected to digital ...

Note: A compact analogue reflectance sensor such as the CNY70 was not used in the Arduino Uno experiments described. Instead, a homemade sensor was assembled using a single infrared LED (IR333C) and a ...

The IR sensor array, which on the palm-sized vehicle consisted of just a handful of components, evolved into a PCB-backed bar nearly 0.5 meters wide. Potentiometer tuning was a fiddly affair, but ...
