Hello,
I have the weather board and I'm using it to teach me some basic electronics... so please excuse the silly questions,
From my understanding the RJ11 for the rain bucket and essentially two Pins a ground (J1/3) and a 3.3/5V (depends what power you are supplying the board) (J1/4) this as far as I've read is connected to a Pull Up resistor which keeps the voltage high.. this is also connected to JP2 pin 2 rain guage pin.
So when the reed switch is triggered it essentially connects the Two pins on the rain guage RJ11 for an instant.. this then pulls the J1/4 down to ground, and the software detects an input....
for manual testing if I have my theory correct it should be possible to manually trigger the J1/3 and J1/4 together via a little switch(if i have not purchased a rain bucket yet) for testing... am I correct here?
Is it possible to get a circuit diagram for the Weather Board (with grove)?
