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)?
Yes, your testing circuit will work. Note, however, that all switches bounce (really!) and your switch may bounce differently depending on the size of the switch. Your computer is way faster than the switch bounce, so you can detect it. Very cool.
We don't give out circuit diagrams, but tell us what part you are interested in and I can post that part of it here!
Many thanks, I tested it and it worked like a charm. I also put a little cap across the input to help with the bounce, I'm quite happy with the testing I've done so far, the anemometer will work the same way so i'm not concerned there, I wanted to know how the ADC was connected to the wind vane.. the pins on the RJ11 are they wired to an Input pin of the ADC? really what i want to know if i solder/connect the adc and a wind vane I should be good to go?
