In this tutorial, I will show how to plug and control
One thing to know: When a Nusbio gpio is open in input mode, it is automatically in pull up mode.
If you do not know what this mean, you can ignore it for now, just follow the tutorials.
- If the gpio has no connection to ground the state is High with a 1 volt value.
- If the gpio has a connection to ground the state is low.
- If the gpio has a connection to ground and a connection to a gpio in high state or to VCC the state is high.
