IR (Infrared Sensor) is an electronic instrument that is used to detect any type of obstacle/object & it is also used to detecting the black & white colour ...

In this circuit, the infrared emitter IRED1 is modulated by connecting its anode (A) to ~38kHz signal yielded by D9 of the Arduino Uno (TP1) while its cathode (K) to a ~1kHz signal available at D8 of ...

The design is very simple, it just houses all the electronics and provides an opening to mount the IR sensor and temperature sensor and also a slot to connect the programming cable to Arduino nano USB ...
