Thank you, appreciate it 🙏

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.

Absolutely great video, so useful! Thank you for sharing

[@robotsanddinosaurs]

Glad it was helpful!

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);
}

How much voltage does the "OUTPUT" give

[@Dark_Matter2]

I think 3.3 volts, its so weak you can only power led light with it. I used transistor bc547 to turn on buzzer and strong led.
