With the Toit platform, developers can treat an ESP32 as a regular computer, installing apps just as easy as on a computer or a phone. Using the high-level language Toit, it is easy to implement functionality and applications while the Toit platform ensures that the device keeps functioning no matter what. This project tests the […]

With the addition of micro:bit to Tinkercad’s Circuits editor, it is now possible to create circuits with other Tinkercad Circuits components and to simulate the operation of the system by controlling these circuits via micro: bit. In light of this new feature, we have prepared a game that can be set up and run in

This device can help you automate your home, backyard, or whatever you want. Step 1: Gather the Components To build this device, you’ll need: ESP8266 x1; 4-stage ripple (binary) counter (I can suggest SN74LS93N) x1; 14-stage ripple counter (CD4020BE is the best choice) x1; Latches (SN74LS75) x6. Since each SN74LS75 consists of 4 latches, only

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

This project builds upon the PIC/TI83+ interface developed by ThomasHenry (see Nuts & Volts August 2013 – A Mathematics Engine for Microcontrollers). Acknowledgment, appreciation, and kudos to him for writing the TI-library for Great Cow Basic that made this project possible. When I recently re-discovered that article, I imagined re-creating the only calculator that was

SmartSpin2K is an open hardware and software DIY module that converts BLE signals from a cycling APP (like Zwift, FulGaz, RGT, Sufferfest, etc.) and uses the information they broadcast to increase and decrease resistance on a spin bike by rotating the resistance knob with a stepper motor. SmartSpin2k receives BLE signals from common cycling peripherals such

In this project we demonstrate BBC micro:bit how to connect it to WiFi and send a notification to a phone without writing a single line of code. The micro:bit comes with a microphone, among the other features. We are going to use it to detect loud sound e.g. clicking fingers and when a loud sound is detected we send

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
