Summary of Probably the Cheapest WIFI Computer in the World (ESP8266+LUA)
The article discusses the ESP-01 module equipped with LUA firmware, enabling it to interact via a serial terminal in a high-level language. It can store programs and control devices remotely at an extremely low cost, ideal for applications like remote temperature sensors. This new software combined with affordable hardware offers a starting point for easy remote access and control, though it is still in early development and may contain bugs. The ESP-01 serves as a compact WiFi-enabled computer capable of real-world tasks for about £2.
Parts used in the ESP-01 LUA WiFi Computer Project:
- ESP-01 WiFi module (ESP8266)
- LUA firmware
- Serial terminal interface (for communication)
- Power supply (to power the ESP-01)
- Sensors or actuators (e.g., temperature sensors, lights) for control tasks
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?
