3 leds and a TSOP4838 IR receiver module. You must check the datasheet before use the IR module to see which pins connect to the power supply and which one delivers the output voltage. I used an ...

Similarly, pin notation for the infrared receiver module is OUT(D2)-GND ... fadeValue); delay(30); } } The following Arduino Sketch tests the four-digit, seven-segment LED display. Needless to say, ...

[Computergeek] made an Arduino Shield in order to use it as an ... he should probably have invited a resistor to the party the two IR LEDs are having.

As described on the Hackster Profar blog, as features go, the Shield sports a reset switch, power LED, Arduino pin 13 LED, Pi GPIO pin 13 LED, headers for full Arduino pin access, and ICSP header for ...
