EDIT - I've found a similar issue, going there instead:


Hi guys!

I am following the Starter Kit projects and I have stumbled across a problem on the Love-o-Meter. When I remove the end conditions to lit the LEDs, the temperature output is always right. If I uncomment the conditions and test, it seems the moment when it lits one LED, the voltage output of the temperature sensor changes drastically. All LEDs lit at once.

I am quite new in electronic, so maybe there something there I didn't quite understand (does lighting a LED affect the current passing by my temperature sensor? This is my hypothesis since the Sensor value never goes down to his reset value, since the LEDs stay lit.

I have attached a photo of my Uno and my code. Thanks!
