Well, here’s a fresh idea! [flurpyflurples] is back from hiatus with the Mintboard, a 40% that fits inside of an Altoids tin. Who could ask for more than a rugged little Bluetooth keyboard with a built-in cover that fits in your pocket? This build started with meticulously measuring the tin to figure out what kind of […]

Hello everyone, welcome back to Techatronic. Currently, phone-controlled lighting has become quite prevalent and easily available in the market. However, today, we’ll demonstrate how to create a similar system at a significantly lower cost. This phone-controlled lighting setup is versatile and can be utilized anywhere by simply plugging it in and operating it via your

There are many ways to lock a door. You could use a keypad, an RFID card, a fingerprint or retina scan, Wi-Fi, Bluetooth, the list goes on. You could even use a regular old metal key. But none of these may be as secure as [mircemk]’s Arduino-based door lock that employs a smartphone’s flashlight as a

It includes highly optimized 2.4 GHz radio IPs for excellent radio performance and minimal power consumption, allowing for exceptional battery life. The BlueNRG-LPS supports Bluetooth Low Energy 5.3, enabling point-to-point connections and Bluetooth Mesh networking to reliably establish
Bluetooth 5.3 SoC: The Future of Wireless Connectivity Continue Reading
When we think about machine learning, our minds often jump to datacenters full of sweating, overheating GPUs. However, lighter-weight hardware can also be used to these ends, as demonstrated by [Nikodem Bartnik] and his latest robot. The robot is charged with autonomously navigating a simple racetrack delineated by cardboard barriers. The robot is based on a

Being the giant fan of LED’s that I am i’m always trying to come up with new ways I can put them throughout my house. Today i’m going to show you how to create a simple, yet extremely eye catching, RGB Bluetooth controlled Shelf lighting system. The beauty of integrating Bluetooth into the system is
Bluetooth RGB Shelf Lighting using Arduino Continue Reading
INTRODUCTION In the guide, I will explain how I managed to send data back and forth between a PC and Arduino via a cheap Bluetooth HC-05 transceiver, which can be found for less than $10 on ebay with the breakout board. The version I have used in this project does not have a breakout board so
Cheap 2-Way Bluetooth Connection Between Arduino and PC Continue Reading
In this project we will use an iPhone to control devices connected to an STM32 device. The project is a starting point for more exciting experiments such as remote controlled robots or any other thing you might want to control in your home. I encourage you to check out the source code which is really
Controlling Devices in Swift With BLE Continue Reading
A friend gave me one of Adafruit’s circuit playgrounds (developer edition) to use, and I wanted to see would it make a good robot controller. The circuit playground is packed full of features like sensors, neo-pixels and even an accelerometer. I wanted to add a L9110 motor controller and create a small bot I could
