How to create a layout (without using a soldering iron) to measure the physical parameters of the environment.<\/strong><\/h4>\n\n

An article for programmers who do not like to design or for electronics who want to get a ready-made complex for mastering programming.<\/p>\n\n

This article will be useful for beginners who are not yet familiar with MCU architecture.<\/p>\n\n

The first steps.<\/strong><\/h3>\n\n

We know from our own experience that when you first pick up a miniature module and see a lot of “little things” on it and you do not know the terminology, do not understand the difference between input and output, look for the usual keyboard and display, there is a feeling that you have no chance master this module. But if you overdo it and connect it to the power supply, it is difficult to understand whether it works.<\/p>\n\n

So what is it – a controller?<\/p><\/blockquote>\n\n

I’m sure most readers know this, but if they don’t, they’ll forgive me for that explanation. When children ask me such questions, I warn that it will not work out. Life may not be enough to understand deeply. But nowadays, everyone thinks they know what the word “computer” means, so let’s try to easily compare a computer (PC) and a controller.<\/p>\n\n

The classic PC is focused on the role of a personal intelligent assistant and therefore these systems are manufactured and sold as a wider or simpler group of devices that are convenient for a person to communicate with a “smart” when performing any information processing work. I called the processor (CPU, central processing unit) installed on the well-known “motherboard” “smart”.<\/p>\n\n

The controllers also have a CPU, but the developer of each controller surrounds the CPU with such electronic components and devices that it performs some specific work. The board ESP12.OLED_V1 has a MCU (Micro controller unit) ESP8266-12F and the MCU has a built-in CPU.<\/p>\n\n

For example, a digital thermometer controller has:<\/p>\n\n
