in the datasheet, the R and I mode where labeled in the opposite way, expected it might have been a mistake in the datasheet, but since I didn't know if the 3.3 would trigger the arduino(while it should) s well as other things I might have made a mistake at I decided to look at someone using it, and luckily the datasheet just had those 2 the wrong way around. also my code for testing was: void setup() { pinMode(7, INPUT); Serial.begin(9600); } void loop() { Serial.println(digitalRead(7)); delay(100); }

What part # or resistor value are the LDR and Thermistor? Thanks for your useful video.

[@robotsanddinosaurs]

You're welcome! Thermistor is 10k I think, not sure about the LDR.
