Refer to the following illustration and connect an LED to [dout 0]. This illustration shows only one LED, but up to four LEDs can be connected to the four outputs and activated with this exercise.
The digital output can only send "off" or "on" signals. The digital outputs can be used to control devices like LEDs, motors and AC100V devices (AC100V devices require an external SSR module). Refer to the cookbook for information on how to connect and control additional devices.
