- Be sure to install bcm2835, wiringPi, python and Webiopi libraries before using them
Instructions for Development Environment
- The routines of the module include Shell, bcm2835, WiringPi, python, and Webiopi routines
- Before using this expansion board, we need to install bcm2835, wiringPi and python libraries for raspberry
- After installing the library, you also need to download the sample program, Copy and release the sample program into the system. For example, the implementation of tar-zxvf RPi_Relay_Board.tar.gz ~, released to / home / pi directory.
- Some example programs have different implementations (such as bcm2835, wiringPi, Python, Shell, Webiopi, etc.), even depending on the same function, they may also rely on different libraries. So be sure to install bcm2835, wiringPi, python and Webiopi libraries before using them.

- Hips: Drape the measuring tape around the widest part of your hips, resting the tape comfortably against your body.
- Length: For tops and dresses, measure from the top of your shoulder to the hem. For strapless dresses, measure from the highest part of the neckline to the hem. For pants and skirts, measure from the top of the waist to the hem.
- Sleeve: With your arm outstretched, measure from the base of your neck to the end of the sleeve hem to determine where the sleeve length will fall on you.
