ПЛК на двух микроконтроллерах ESP8266 NodeMCU иArduino Nano.Проект создан для управления теплым полом на лоджии с датчиков температуры Dallas 18B20, которые расположены на улице, на лоджии. Так-же для передачи показаний температуры по mqttнасервера.
Original project I found [here](https://www.hackster.io/sfrwmaker/soldering-iron-controller-for-hakko-907-v-2-fc75d7). Thank the Alexander. I tweaked it for my box. All the steps with in this [blog](http://bit.ly/2ZMqTdI)
zeus trigger is an Arduino based Photographic trigger under developement. This here is a shield for arduino nano.
Its main features are:-
* IR trigger
* Drop Photography (drop collision)
* Laser Trigger
* Sound Trigger
* Shock Trigg...
This is a basic firework launch controller based around an arduino nano/ micro. It can also be used to controll any dc appliance in a timed sequence, up to 24A/10A. The boards are designed with osome costumizability, as it is'nt a completeed project (there will more then likely be a v3.0) and has a lot of unused pins on ics and connectors.

**How to choose the right Arduino board should be a headache problem for many green hands.**
As we know the Arduino development board is a big family. There are dozens of different development boards listed on the official website of Arduino.
Especially the Arduino official team decided to use a Creative Commons (CC) license to keep the idea of openness alive. Under the CC license, anyone is all...
