I now have a lamp connected to a RPi Zero W and another Raspberry Pi 3 connected to XMOS. The RPi 3 has AVS "Alexa" running on it.
What I want to do is to set up voice control so that the RPi 3 can send instructions to the RPi Zero to trigger the lamp on/off.
I want to know how I can set up a wireless link between the two RPI. Is it better if I do it with "ad-hoc" or "infrastructure mode" because in the end I want to have the RPi 3 control multiple lamps not just 1 lamp. I am new to this so it would be nice if someone has a link to some similar projects or tutorials.
