Pete has a cool project where he goes over setup of diminutive but quite capable ESP8266 chip with LUA firmware. Though still at a demo stage to illustrate that the device can be made to operate in a standalone mode with programmed firmware able to react and respond to commands and instructions as opposed to it being used purely as a Wifi enabler board for a microcomputer based project.
In his own words…
What do I mean by a computer in this context? I mean a device capable of connecting to the outside world via WIFI and doing real things – like flashing a light or reading a sensor – and having a human interface installed…. I’m stretching this a little, but essentially right now as I write this I have in front of me a computer capable of responding to commands in a terminal window – for £2 – does that have your interest?
Adding this to the long list of projects to try out.
