This is the command line and python functions to control the Sequent Microsystems 8 Relay Card for Raspberry PI Ver. 3. If you have Ver. 1-2 with screw-type connectors download from here.

~$ sudo raspi-config

Usage

~$ git clone https://github.com/SequentMicrosystems/8relay-rpi.git

~/8relay-rpi$ sudo make install

Now you can access all the functions of the relays board through the command "8relay". Use -h option for help:

~$ 8relay -h
