Step 2: Wiring
DHT-22;
From left first pin goes to 5V second pin goes to Digital Pin 2 we are not using third pin, and last pin goes to GND
NOKIA 5110 LCD
RST = 6
CE= 7
DC= 5
DIN(MOSI) = 4
CLK = 3
VCC = 3.3V (dont connect to 5v it will cook the display)
LIGHT(BL) = GND (this can be different depending on the producers if the light doesnt work try connecting to 5V with a resistor or to 3.3V)
GND = GND
