Reference: RPi Serial ConnectionThis article from: Http://www.raspberry-projects.com/pi/programming-in-c/uart-serial-port/using-the-uartUsing the UARTIf you is running Raspbian or similar then the UART would be used as a serial console. Using a suitable cable, such as the Ttl-232r-3v3-we, you can connect it to your PC and using some simple terminal software Set to 115200-8-n-1 use the command line interface to the

Introduced The DHT11 is a cheap accessory that includes temperature and humidity sensors, and the code is easy to use. This article describes if you use DHT11 in a Raspberry Pi, the code is python. If you have any questions, please leave a comment below. Wiring VCC Connection 5V or 3.3V Data is connected to the Gpio (I'm picking up the BCM pin 16th, the physical pin is 36) GND Co
