Allocation of pins for room's controllers and sensors

Room 1:

  • Sensor: PC8
  • Light: PB14
  • Heater: PC9

Room 2:

  • Sensor: PC6
  • Light: PB15
  • Heater: PB8

Room 3:

  • Sensor: PC5
  • Heater: PB9

PINOUT for digital temperature sensor DS18B20

                                            NUCLEO PIN                SENSOR PIN
                                   PC8 | PC6 | PC5  <------------------>  DQ
                                               +5V  <------------------>  VDD (+)
                                               GND  <------------------>  GND (-)

Pull up resistor should be connected between pin VDD and DQ to assure correct work of temperature sensor.
