In the previous entry of our home automation course with arduino we saw how to install software and make the first connection with arduino compatible equipment.
In this new entry we will see how to make a new connection, with a second arduino comatible , although we recommend our professional hardware for domotica with arduino.
You can give different icons to different connections, so you can access to differentiate these easily, see some examples about this.
Is not necessary that the arduino are in the same installation, can make connections with different installations and use them from a single app.
We go with the video explaining how to create more connections.
