|
|
* An IR LED circuit *MUST* be connected to ESP8266 GPIO4.
|
|
*
|
|
* TL;DR: The IR LED needs to be driven by a transistor for a good result.
|
|
*
|
|
* Suggested circuit:
|
|
* https://github.com/markszabo/IRremoteESP8266/wiki#ir-sending
|
|
*
|
|
* Common mistakes & tips:
|
|
* * Don't just connect the IR LED directly to the pin, it won't
|
|
* have enough current to drive the IR LED effectively.
|
|
* * Make sure you have the IR LED polarity correct.
|
|
* See: https://learn.sparkfun.com/tutorials/polarity/diode-and-led-polarity
|
|
* * Typical digital camera/phones can be used to see if the IR LED is flashed.
|
|
* Replace the IR LED with a normal LED if you don't have a digital camera
|
|
* when debugging.
|
|
* * Avoid using the following pins unless you really know what you are doing:
|
|
* * Pin 0/D3: Can interfere with the boot/program mode & support circuits.
|
|
* * Pin 1/TX/TXD0: Any serial transmissions from the ESP8266 will interfere.
|
|
* * Pin 3/RX/RXD0: Any serial transmissions to the ESP8266 will interfere.
|
|
* * ESP-01 modules are tricky. We suggest you use a module with more GPIOs
|
|
* for your first time. e.g. ESP-12 etc.
