• I contacted AJ Keller who wrote the Analog Read widget and is one of the developers of the board, as far as I know. My idea seemed simple: Take a temperature sensor which provides an analog voltage, read that via the widget and calculate the temper…

• Yes, that is more or less what I tried. Unfortunately in my case the Analog Read widget did not seem to react to any voltage I applied to the pins. And the process of trying to fix it resulted in the board not sending any data.

• So, the current status is not the best I'm afraid. I updated the firmware of the Cyton board and the two RFduino modules and now I cannot receive any data. I can start the system in the GUI, but on turning the data stream on, there's no data showing…

• Thank you again. Yes, I already pressed the "Turn Analog Read On" and I tested the other pins, with no better result than the D12 pin. I'll contact him via mail and keep this post updated.

• Well, I don't get it. It seems that the whole analog read widget does not make any sense. I applied 0V and 3.3V on the D12 input pin to get the range of the readout, but the widget does not seem to notice. The values fluctuate roughly between -150 a…

• The LM35 should be working fine with 3.3V according to the datasheet (page 4). I'll try to check the analog widget with other voltages. What I'm looking for is some documentation on that widget. There are a few questions that even the source code c…

• I played a bit with the analog read widget and I'm not sure if it works. Unfortunately I wasn't able to find similar topics or some sort of tutorial on the OpenBCI websites for this matter. I connected my temperature sensor to GND, VDD , and D12 on…

• Thank you again very much. Using the analog input could be a much better idea than my initial thought. I have a LM35 analog temperature sensor at hand, which produces a voltage output from -1V to 6V. Unfortunately I have found no specifications or i…

• Thank you William. I already used this search functions, but I'm afraid I don't see the wood for the trees. Anyway, I'll have a look at the firmware. If I'm not thinking in the wrong direction, it should be possible to use the Serial1 connection to…
