Hey all,
Me and a friend are trying to hook-up a DHT11 sensor from dfrobot.com into pduino.
We have dl/d some code from here http://www.nuelectronics.com/download/projects/sensor_pde/dht11.pde and uploaded that to the board via the arduino program.
We are receiving unknown data from the sensor and board, though there is no fluctuation from the sensor when altering the humidity and temp. Data from console attached.
As we are both rather new to the wonderful world of arduino we're not sure of our next move?
Any pointers/advice/code gratefully accepted.
Pd-extended 0.42.5 Pduino 0.5 beta 8 Firmata 2.1
Very best wishes,
Julian
hey guys,
the firmware you are using (dht11.pde) sends text messages, which a human can read on the serial console, but [pduino] can't interpret this. with the "AnalogFirmata" in Firmatas examples directory you should be able to read _any_ analog sensor. the other option is, that you change that software to send the sensor values as integers and read them from the serial port pd with [comport].
hope that helps ... have fun, ub

Hey ub,
Thanks for the triple response:)
I think we got the wrong end of the stick somewhat.
We thought that the pduino firmata was akin to an O.S. and the sketches we uploaded to the arduino was like software. Guess this is not the case then. Will put the pdiono firmata back on again and have another go.
We went googling because the original pduino firmata wasn't working and found that piece of code.
Will try again and report back.
Cheers,
Julian

It should be pretty straightforward to turn dht11.pde into a Firmata-
based firmware, basically just replace the Serial.print() statements
with Firmata.sendAnalog() and assign a channel for temp and humidity.
You could also do it with strings if you wanted.
