Raspberry Pi System Load LED

A script for your Raspberry Pi that will show the system load through an external RGB LED.

---

How it works

The color range goes from green to red depending on the system load as it follows:

• under 25%: quarter brightness starting with pure green
• under 50%: half brightness yellow nuances
• over 50%: full brightness
• over 60%: slowly pulsating orange light
• over 80%: fast pulsating red light

---

Running the script

Download RPI-SystemLoad-LED.py, put it wherever you want and then run it with:

python3 RPI-SystemLoad-LED.py

You might want to set it to run at startup :)

Requirements

• Raspberry Pi
• Raspbian OS (easiest as it already has every software thing you may need)
• SMD 5050 LED board (you can obviously build it yourself too but you'll probably get a bulky thing)
• Edit the script so it'll point to the right LED GPIO pins

My config

• Raspberry Pi 3 Model B
• Raspbian OS
• THIS SMD 5050 LED board
• RGB pins: 15, 13, 11
• Ground pin: 9
