Connect the VCC and GND of the module to the 5V and GND pins of the Arduino. Then connect the DATA pin to Arduino’s digital pin 2. We communicate with DHT22 through this pin. Arduino DHT22 Code for Interfacing the Sensor Module Now let’s look at the code for interfacing the DHT22...
In this instructable, explains connecting the 320x480, 3.5Inch TFT LCD, with ILI9488 driver and SPI interfacing into Arduino. The LCD can be connected to the Arduinos SPI bus. It needs minimum number of port pins (4). The DHT22 (AM2302) is a high precision temperature sensor module, p...
