Each end of the strip has 4 wire leads leading to a port, female for input and male for output.
If you do not require connection to another string you can cut off the male output connector and utilize it to connect to the female connector. Connectors can likewise be removed completely if not necessary for your application-- there is lots of wire result in permit a direct-solder connection.
For you Arduino users we highly suggest the open-source fastspi library as jumping point for your very own code.
The WS2801 utilizes a 2-wire serial data connection, just like SPI or I2C. ICs are chained together meanings that entire strings can be regulated making use of simply 2 pins on your microcontroller.
Data is clocked in beginning with the MSB of the red gray scale data and ending with the LSB of the blue gray scale data.
