I ordered Universal IR Receiver and I got HW-477 module with VS1838B IR Sensor.
Good thing is datasheet for VS1838B is available but not for HW-477.
VS1838B pins as: Ref
Signal | GND | VCC
while HW-477 says:
- | R | G
Can't understand which one to follow and R is for Receiver? G is for GND and what is - (minus sign) for?
So can anyone help me with ( - R G ) of HW-477 ?
