Hi,
Thank you for the manual, I have ordered a couple of these but cannot seem to get the transmitter to work. The way I understand this is as follows.
Transmitter:
The digital IO pins from the arduino connects to the pins 1 2 3 4 on the transmitter depending wether it is a 4 or 2 channel relay. Then another Digital IO pin from the arduino connects to the TE. The 5v+ from the arduino is connected to A and GND from the arduino is connected where the image says (caution: GND is here). Then when the digital IO pin connected to TE is set HIGH and one of the PINS connected to 1 2 3 4 is set HIGH that channel will transmit.
Reciever:
+12 on the reciever is connected to a positive power supply 9v~12v and the - is connected to GND of the Power supply.
Now my concerns are both TE, A and GND of the transmitter have 2 holes for soldering the wires onto, which hole should I use. Also is there any indication when the transmitter transmits a signal such as a led that goes on. I am not seeing any indication.
Any help would be welcome.
