🎚 Pinguino 18F4550

Pinguino board, based on Pic18F4550, Programing Arduino and Pic

First at all, the Pinguino Project is Open Source which means that We can access the project information from the official website: pinguino.cc

We will find a different models of boards, in this case first we need to go to the basic schematic circuit and based on it, we are going to make changes or add additional circuit, but the the basic circuit will always stay.

Main features:
▫️ Open Source
▫️ Programmable by his own IDE, Pinguino IDE
▫️ Language of programming : Arduino (Some little changes)
▫️ 28 Digital Outputs
▫️ 5 Analog Inputs
▫️ 2 PWM Outputs
▫️ +5V Power Pin
▫️ +3.3V Power Pin
▫️ Powering by USB or External Source 9-12V

📟 3D printed Smart Chessboard (Play Online or Against Raspberry Pi)

Though this board has a great single player mode, If you build two, and bond them together digitally you can then send one to a friend or loved one so you that you can play chess together over the internet with real chess pieces and only a few seconds of delay.

Main Features:
▫️ Check your moves are legal and warn you when you don't play by the rules
▫️ Suggest what would be a good next move for you
▫️ Entirely 3D printable including the chess pieces
▫️ Very cool looking LED lighting to convey the game status and provide the lighting for evening games
▫️ Smart control panel which guides you through how to use the board with intelligent backlighting
▫️ Small and low cost OLED screen to help guide you through using it
▫️ Powered by USB, so you can connect it to mains or run it from a common USB battery pack for untethered play

🚰 Arduino controlled smart irrigation system

There are plenty of projects out there that automate irrigation. Many focus on the problem of automatically reacting to dry soil by opening a single valve, but a fully automated system with one valve is not what I want for my lawn. I do not want the sprinklers to turn on unexpectedly and I had to solve a different type of problem: Managing a specific irrigation program with individual control over each sprinkler.

The brains in this case is an Arduino Nano 33 IoT, which is the first time I used one of these. In principle, you should be able to use pretty much any microcontroller, but if you want to control it via Wi-Fi, you quite obviously need one with Wi-Fi capabilities. If you want to run my code with only minor modifications, you probably also want to go for the Arduino, but if you do not mind some adaptation, an ESP32 would probably be the cheaper and much more common choice.
