Playing around with IR sending and receiving.
Got myself the KY-005 IR board and it turns out that in order to transmit signals, the IRRemote library requires you to connect the signal pin to pin 3 on your Arduino.
I got an esp32 and it doesn't show any pin 3. What can I do now? ( Link to a picture of my board as I couldnt upload it https://photos.app.goo.gl/kfPAcR33cKxEkYYx6 )
Thanks for any help.
