I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the ... else { digitalWrite(led4, HIGH); itsONled[4] = 1; } break; The array ...

Here is the diagram of my Arduino infrared close proximity sensor ... shifts to a logic-high (H) state for a while when an object appears within sight of the infrared sensor assembly (IRED1 and IR1).

Of course you could do something else entirely with it simply by firing up the Arduino IDE and writing some new code for the device’s ATmega328P microcontroller. As with the IR-enabled ESP8266 ...

Here’s a way to program an Arduino wirelessly while still using the stock IDE. It uses an alternative bootloader called SuperDuplex along with an IR receiver like the ones used for TV remotes.

The collimated light beam discharged by the IR LED produces the uniform light spot necessary for use in optical encoders. And in addition to its narrow directivity, the L8506 also offers a high ...
