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 ...

A project-based on Arduino Uno and IR sensors is used to automatically switch on and switch off a washroom’s light (Automated Washroom Light) ...

These modules, typically seen in line following robots, are ideally suitable for white/black line detection. You can also see them in certain entry alarm systems. HW-006 Module – A Brief Overview The ...

We will monitor the module’s output and will change the Arduino onboard LED state according to it. Hall Effect Sensor Pinout The Hall effect sensor module has 4 pins VCC, GND, DO, and AO. We can ...
