4 20MA TRANSMITTER CIRCUIT DIAGRAM

KS0487 Keyestudio 37 in 1 Sensor Kit upgrade v3.0
The circuit in this experiment can produce sound. Normally, the experiment can be done with a buzzer or a speaker, while buzzer is simpler and easier to use. Working current: ≥20mA; Connection Diagram: For IR Transmitter:as same as the above diagram, but note that Arduino-IRremote only supports D3 as transmitter. For IR Receiver
