A USB hub that’s also a dev board and an I2C, GPIO, and SPI bridge In Addition To Being A 4-Port USB 2 High-Speed Hub, This Programmable USB Hub Is Also: A CircuitPython based development board. A bridge between your computer and I2C (via Sparkfun Qwiic connectors), GPIO, and SPI (via its mikroBUS header). A power supply, providing 6 A of […]
This instructables show how to use micro:bit to make a simple digital compass. Step 1: Get a Micro:bit If you not yet have a micro:bit, you may get a micro:bit here: https://microbit.org/resellers/ Step 2: Optional: Battery Holder If you want to make the digital compass portable, you may consider get a battery holder. Any 3V battery
For this project, my co-worker – @descartez and I created an awesome tic tac toe game using the radio functionality of microbits. If you haven’t heard of microbits before, they’re an awesome microcontroller designed to teach kids programming. They have A TON of functionality including what we used for this project; the LED matrix, 2 buttons, and
All the lights in my house are smart so I’ve got pretty used to yelling at them to switch on and off, but it ends up making me look dumb when I yell at a light that isn’t. And I look especially dumb when yelling at candles. Normally this isn’t too much of a problem,
This Instructable will allow you to build a drink coaster with a weight sensor in it. The sensor will determine the amount of liquid in the glass placed on the coaster and send this information through WiFi to a webpage. Additionally, the coaster have LED lights installed that will change color depending on the amount
A Nintendo Advantage inspired controller to use with the NES Classic Edition, also known as the NES Mini. This project is based off of the Wii RetroPad Adapter project by Bruno Freitas. I made this because of bad experiences with 3rd party controllers lagging and/or just not working. Main “Advantages” over the stock controller and some other 3rd
An ultra-simple power solution using USB Elektor author Alfred Rosenkränzer presented a wonderfully simple differential probe for oscilloscopes, based around the AD8479 precision differential amplifier. I built one of them immediately and found it particularly suitable for measurements in the audio range, for example. But one small detail was not covered in this article:

The ESP32 has about 4MB of internal flash memory and since the data stored within the flash memory is retained even when power is recycled, it becomes super useful for applications where you need to keep certain amount of data even after power off. For today’s tutorial, we will learn how to read and write
The present PROJECT describes a design and implementation of an infrared (IR) remote controlled RoboCar which can be used for various automated unmanned control applications. I have designed remote controlled RoboCar(left-right/front-back motion). The entire system is based on microcontroller (Atmega32) that makes the control system smarter and easy to modify for other applications. It enables
