This command-line tool controls the LEDs on the Blinkt! add-on board for the Raspberry Pi. All functions are available from the command line; no additional programming needed. Can be used within shell scripts.

To clear the LEDs to their default state, type:

blinkt clear

To turn on all the LEDs blue, type:

blinkt blue

The named colors available are red coral orange gold yellow lime green aqua blue purple pink white.

Pixels are numbered 0-7 from left to right. To turn pixel 1 yellow, type:

blinkt p1 yellow

To specify color by RGB, type, e.g.:

blinkt rgb 10 0 50

To turn on the left 4 LEDs blue and right 4 LEDs red, type:

blinkt 11110000 blue
blinkt 00001111 red

To change the brightness of all pixels to 12, type:

blinkt bright 12

For more information, see man page.

• Raspbian Bullseye

sudo apt install git
sudo apt install pigpio
git clone https://github.com/7402/blinkt.git
cd blinkt
make
sudo make install

To run blinkt, either use sudo:

sudo blinkt

or start the pigpiod daemon:

sudo pigpiod
blinkt

To auto-start pigpiod on boot:

sudo systemctl enable pigpiod

(The LEDs respond faster when not using the daemon.)

If you are viewing your Blinkt! board upside-down from its standard orientation, i.e., the letters "BLINKT!" on the circuit board are upside down, type this command to adjust the numbering direction:

blinkt right
