I have a KY-005 infrared transmitter connected to my Arduino Uno. But currently I can't get it to work. On this website it says that you must connect the led directly to a digital pin on the Arduino, which I have not done (I connected it in series with a 220 ohm resistor. Because i don’t Thrust the led can handle it)

Is it correct that you can/must connect it directly?

Update: i hooked up the led directly to the arduino pin 3 (not +5V) and that did. it now works
