Arduino Code Complexity. IR Sensor: Simple digital read - just check HIGH/LOW state (as shown in our code above) Ultrasonic Sensor: Requires timing calculations to convert sound travel time to ...

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 ...

How to connect the TSOP4838 to an Arduino to read the transmitted codes By using a cheap integrated IR receiver/decoder device (the venerable TSOP4838 ), most of the hard work is done for you!

The Vout pins of IR Module1 and IR Module2 are the output pins connected to pins 8 and 7 of Arduino Uno, respectively. The output of each sensor will be either 5V (high) or 0V (low) based on the ...
