ESP32 control via UDP datagrams

-
Image
Today I would like to point out the possibility of controlling the ESP32 development board by sending UDP messages for easy ON / OFF control. This is one of the easiest ways to send data, process it, and take action based on the information received. ESP32 is a platform that is used in most cases in connection with WiFi connectivity as a webserver or webclient, which connects to a remote server and POST, GET method, or with the integration of the MQTT protocol, sends data to a remote server / guest. Libraries for ESP32 written in C++ Arduino core (framework) also allows to use asynchronous UDP libraries for sending and receiving data. An interesting feature is asynchronicity, as they work in the "background" and the user does not have to program complex functions to accept connections, process information, etc. To send data to the ESP32 development board, we need a simple UDP client. In my case, I used the Windows version of the relatively well-known Packet Sender client. It

Web scraper via Arduino & NodeMCU & ESP32

-
Image
Today, we will devote our microcontroller and its general use to a rather unusual purpose. Specifically, I will be talking about how I made a microcontroller from a webscraper. (If this can be called when processing your own backend information). As many of you know, a web scraper is a device that performs the task of retrieving information from that web site. The most wanted information from websites is e-mail addresses, phone numbers. Recently, however, this phenomenon is also used for a variety of statistical tasks where the scraper receives data on products, their prices, and evaluates them. Even similar devices are used as robots for trading with cryptomas or common names. At the most appropriate time (statistically) the robot pedal and bought another - a suitable menu with a rising tendency. In my case, I was interested in getting information from websites, specifically phone numbers and email addresses. We will therefore go directly to the realization. I have used 3 kinds

Direct current measurement - Arduino

-
Image
Today I will introduce several available Arduino sensors that can be used in DC projects. This means with a rated supply voltage of 5V with max. 5V output. Current measurement ACS712 An ACS712 sensor, also referred to as ACS712ELC-XXA-XX, indicates the value of amers to measure DC (and AC). The sensor uses a hall sensor to measure the current flow. Versions for 5A, 20A, 30A are available. For all versions, the nominal output voltage is 2.5V at 0A. The sensor has an analog output with a range of 0 to 5V. Module 5A   20A 30A Vcc 5V 5V 5V Max measure value -5 to +5A -20 to 20A -30 to 30A Voltage at 0A Vcc/2 --> 2.5V Vcc/2 --> 2.5V Vcc/2 --> 2.5V One amp step 185mV / A 100mV / A 66mV / A Chip version ACS712ELC-05A ACS712ELC-20A ACS712ELC-30A The module contains a terminal block for connecting the conductor through which the current flows in series. The module does not include a PCB mounting hole. There are versions from other manufacturers that also inclu
