I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

pinMode(IR_Pin, INPUT); // make the IR pin an INPUT: pinMode(GLED_Pin, OUTPUT); // make the LED pin an OUTPUT: pinMode(RLED_Pin, OUTPUT); // make the LED pin an input: ...

ESP8266 WITH IR-SENSOR PROGRAM Basic. Certainly! Below is a simple example of an ESP8266 program using an IR sensor. This example assumes you are using the Arduino IDE with the ESP8266 board support ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine ...
