LEDs are used for just about every project! I am not sure that we will ever have enough of these things.
LEDs have countless uses. We find ourselves using them all of the time including for the following:
- Status Reporting
- Circuit Testing
- Low Power Illumination
- On/Off Status
Sometimes we even use them as an easy way to find places where there is a break in a circuit on low voltage PCBs.
It's always nice to have a selection within reach.
In this project, we will hook up a simple LED circuit using the GPIO of a Raspberry Pi and have NodifyMe Studio turn on the LED remotely.
The RPi Gpio service provides nodes that allow you to set and read the state of the pins of a Raspberry Pi. Note: This service must be run with root privileges.
