This is a project for school. Connect an adafruit dashboard to control an LED on your arduino board.
Step-by-step
Install PyFirmata, this requires pip to be installed. To install PyFirmata, open CMD and run "pip install Pyfirmata", this should run a quick install, some instances of python already come installed with pyfirmata.
Connect your arduino board with an LED
Download StandardFirmata.ino
Upload the code to your arduino
Download Adafruit.py
Change the adafruit key to your own (the one in the script will not work and is simply a placeholder)
Create one or two blocks, one toggle, and another can be a value
rename the toggle block feed to "digital", and rename a value block to "counter"
Run the python script
if you've done everything correctly you should be able to control an LED with the toggle button on your dashboard :)
You can use the "Mysql with adafruit (published).py" file I've released if you want to upload your logs to a mysql database.
