+## Hardware: heating
+
+### Photoresistor
+
+Schematics:
+
+1. A0 -> 10K Ohm -> GND
+2. A0 -> Photoresistor -> 3V3
+
+Assembly:
+
+1. Put isolation band on the legs
+2. Solder legs to dupont wire (the other end has to be male)
+3. Bath it in the insulation varnish
+4. Think the isolation band with a fan
+
+Color coding for RJ45 cable:
+
+- orange: furnace
+- blue: floor
+
+5528 photoresistor: 8-20K resistance by brightness, up to 1 MOhm.
+Brightness range is 1.47 - 2.2V.
+Darkness is 3.267V.
