Just two weeks ago, the pico, a new microcontroller, the pico, was released by the Raspberry Pi Foundation, well known for the incredibly successful series of Raspberry Pi single-board computers. The new microcontroller uses a brand new chip, designed in-house, the RP2040. It has two 32-bit cores running by default at 125MHz. It has been criticised […]

In this IoT project, I have shown how to make IoT-based Smart Home Automation using Multiple NodeMCU ESP8266 network to control all the home appliances from the pushbuttons & Blynk App. If the internet is not available, then you can control the home appliances from manual switches. During the article, I have shown all the steps to make this smart

The new Raspberry Pi Pico offers Dual Cores and Interrupts if you use MicroPython. I thought I would give it a go and try explain some of the pitfalls to avoid. This project keeps the action running on the two cores very simple, so that we can concentrate on new aspects of the code: setting
So, in this video we’ll be seeing how to build this haptic feedback device and the ambient light system which reacts to the player’s health value inside a PC game! For that we’ll be using the ESP-NOW protocol, about which we learnt in the previous video and also see how to use different RGB LEDs

This project is a follow up of the Illuminated Presents project that I posted earlier. My wife really liked the Illuminated Presents but kept them as Cubes and did not put a bow around it to turn them into presents. Because of this success I created a second one – called Illuminate Cubes since that is what
Introduction: I built this project as a birthday present for my oldest daughter. She had recently moved far from home and I wanted her to know her family was still there for her. I chose a Lord of the Rings theme and aesthetic because she and I had watched the movies together as she was

So I have yet again over-engineered a task, this time, a freeze-dried coffee dispenser. Why you ask, well the obvious first, it’s super fun and second, it’s the best way to learn new skills. I’m a real noob when it comes to the inner workings of microcontrollers but I really want to know how I
