This article describes the ESP-01, fitted with LUA firmware that is able to converse with a serial terminal in a high level language, store programs and data, turn things on and off in a package that costs almost nothing. The possibilities for ridiculously cheap remote temperature sensors and more are finally here. The software is new, the hardware is relatively new – and we need people working on software to make remote access easy. No guarantees here as I have only tested (and reported on) some of the features. Am important fix that made this practical to use only came through in the early hours of this morning – there will be bugs but at least it’s a starting point – all you have to lose is a little time.
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?
