I have a ND+v1 using 4.2 firmware. I have a LM35 temperature sensor wired to analog pin 5 and a photocell wired to analog pin 0. The temperature sensor works great until I connect the PhotoCell then the temp immediately jumps anywhere from 10 to 30 degrees.
The temperature sensor logic is throwing away the first reading and then averaging the next 10 readings and it's consistent and accurate.
The photocell logic is triggered maybe once a day so it's not doing a lot of readings, it just has to be connected to bother the LM35.
I've read many articles but haven't been able to figure this one out. Can anyone advise?
