How to Install PyCharm Community Python IDE and Create a ProjectIn this ebook we are going to;Download, install & setup PyCharm Community Edition.Create a basic 'hello world' starter project.Create a real Python Guess the Number terminal application.Make a desktop short cut to run the terminal application.Have fun & learn things.

ESP32 Wi-Fi Web Server How to Control a Relay Locally Without InternetControl Robots, Model Railways, Maker Projects etc.Ever wanted to control a relay (or maybe a servo), attached to one of our projects on the other side of the room. Or the other end of the house, but wanted to keep it all simple and low cost. Even worse, your internet connection drops out just when you want to stop the Robot from chasing the cat!Well, this book might just help…In this book we will be setting up an ESP32 web server locally, without any Internet connection; serving a HTML page, plus a CSS page to present the HTML page at an IP Address; ready to be commanded by you to do things. Amazing! YES! No, not really... but it is a really good foundation for all sorts of robotics, home controlling and making fun stuff do stuff.So lets get started...

How to Install PyCharm Community Python IDE and Create a ProjectIn this ebook we are going to;Download, install & setup PyCharm Community Edition.Create a ToDo GUI application.Make the application into a standalone indows execuatable.Have fun & learn things.

Raspberry Pi PicoW Web Server Relay Control from Anywhere Using MicroPython and Tunnelling SoftwareIn this book we are going to;Build a breadboard circuit using the Raspberry Pi PicoW low-cost, high-performance microcontroller board, combined with a Relay and some jumper leads.Install & set-up the Thonny Python IDEInstall MicroPython Firmware on your Raspberry Pi PicoWMake a MicroPython Web Server program to run on the Raspberry Pi PicoW that will  allow us to switch the Relay On/OFF when we want, using a Web Browser connected locally via WiFi.Finally, we will install & set-up ngrok Secure Tunnels.Using ngrok Tunnelling Software, we will make our Raspberry Pi PicoW Web Server available from anywhere that has an internet connection.All developed under Windows 11 with the code available for download.Sounds like it might be fun, let's go.

ESP32 Web Server Monitor Temperature and Control a Relay over local Wi-Fi Introduction.By utilizing sensors and relays it is possible to monitor environmental conditions such as temperature and humidity even when not close at hand. "e;Why would I want to do that?"e; you say... Imagine, if you will, the ability to automatically turn on/off fans or watering systems based on certain environmental conditions. Yes? An automated monitoring system can be implemented in your greenhouse to turn on/off pumps or fans based on the temperature and humidity. A similar system can also come in handy for the baby's room, for turning on a fan, or perhaps even the dog house, cat house and hen house, ensuring a comfortable and safe environment for your loved onesThis book will take you through setting up and coding the first step; monitoring the temperature and humidity to control the relay (the bit that does all the work). After that, you just need to connect the relay to you system for automation (not in this book)What we are going to do.In this book we are going to;Build a breadboard circuit using the ESP32 low-cost, high performance microcontroller board. A DHT22 Temperature and Humidity Sensor, combined with a Relay and some jumper leads.Install & set-up the Arduino IDE & Libraries we will be using.Prepare and upload ESP32 code and support pages, for a WebSocket Web Server program serving an HTML page broadcasting temperature and humidity value to connected clients. As well as allowing switching of a Relay On/Off when we want, via any Web Browser on the local Wi-Fi network.All developed under Windows 10/11 ( code available for download).Sounds like something that might be useful, let's go.
