A motion sensitive firefly-filled pickle-jar that gets brighter when you move it, and then settles down to just twinkle a bit when its still. This project was inspired by a workshop led by Lila Finch and the great folks doing tinkering / creative learning at UC Boulder. Supplies: A microbit, v1 will do AA battery […]

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

As a second year STEM teacher, I’ve been using the Makey Makey kits with my 4th, 5th, and 6th graders to explore circuitry, electricity, and to just have some fun! Students have had their choice of projects, ranging from interactive displays to musical instruments using Makey Makey and Scratch, and have truly enjoyed applying the

I was working on an unrelated project that utilizes Bluetooth, I had to test the communication so I built one of the Arduino test circuits. The light contains all of the electronics, microcontroller and battery which can be recharged VIA USB. It uses really strong magnets to attach it to my clothes. I 3D printed

I bought this book to improve my Micropython-skills: MicroPython for ESP8266 Development Workshop by Agus Kurniawan. This book is a very good start, the I2C project uses a PCF8591 module. But no DAC programming example so I had to figure that out by myself 🙂 . Supplies: What do we need: – Wemos D1R2 (or

In this article we’re going to build three projects utilizing AI functions of Codecraft, a graphical programming environment based on Scratch 3.0. Codecraft is developed and maintained by TinkerGen education and is free to use. AI and it’s subset, machine learning, has become an integral part of our lives in the last 10 years. School

I saw this LED bar-graph on the Pimoroni site and thought it might be an inexpensive and fun project while undertaking covid-19 lockdown. It contains 24 LEDS, a red and a green, in each of its 12 segments, so in theory you should be able to display red, green and yellow. Normally you would expect

This is a second project in series on coronavirus protection from TinkerGen. You can find the first article here. We firmly believe that with humanity’s collective efforts, current epidemic will soon come to an end. But even after COVID-19 has passed we should remain vigilant and keep the good habits we (hopefully) developed during these tough times. The
