Sensor data collection from STM32 and SHT85 using Bluetooth Low Energy
bleuio Feb 18,2022
When the BleuIO Dongle is connected to the Nucleo boards USB port, the STM32 will recognize it and start advertising the sensor values that it reads from the SHT85 along with the sensor serial number. It will update these values every 10 seconds.Setup the projectPart 1 : Download the projectGet project https://github.com/smart-sensor-devices-ab/stm32_bleuio_SHT85_exampleEither clone the project, or download it as a zip file and unzip it, into your STM32CubeIDE workspace.Part 2 : Importing a...

Sunmachine-A2 - smart lighting system
Blach Jan 31,2022
The driver for WS2812, SK6812 or similar LED strips controlled via Bluetooth LE. It supports both RGB and WWA LEDs. This driver uses motion and light sensors, so in automatic mode it can turn on the light when it detects someone's presence in the dark.In addition to this board, you also need a 5V power supply, WS2812-like LED strip and optionally Hammond 1551V3 enclosure (so you can hang it on the wall or ceiling).

Power Supply Board for Bluetooth module on tube radio
Caldeira Jan 22,2022
A convenient supply and I/O board for adding a bluetooth module to a tube radio. The bluetooth modules are readily available, so this board serves to provide the required DC supply to the board using the heater voltage as a source, and then routing the audio to the radio's pickup input. It can also create a mono signal if the radio only accepts mono. The supply is isolated to avoid ground loops buzz using a DC-DC converter.

2.1 Amplifier LM1875 - TDA7294 With bluetooth
barita Dec 09,2021
In this project I want to make a bluetooth 2.1 amplifier with a simple and compact design that only requires 3 chip-amp ICs, namely LM1875 as the satellite and TDA7294 for the subwoofer amplifier.The subwoofer's cut freq can be adjusted by turning the available trimpot.There is a separate volume control for the satellite and volume for the subwoofer.This amp includes a bluetooth receiver system at its input, and for the bluetooth module it uses a third-party bluetooth module, namely JDY-62A whic...

First Ever Bluetooth Home Automation Shield For Arduino
Krrish Verma Dec 01,2021
If you ever wanted to learn or make a Bluetooth home automation system using Arduino, you must have searched youtube about it. If you go through all the tutorials, they use Arduino and many wires to connect it to the relay board, HC05 Module, etc. That looks very untidy, and its practical application is also limited.When I searched the internet, I couldn't find any relay shield available for Arduino with Hc05 module pins.So I decided to create the first-ever Bluetooth home automation shield for ...

Bluetooth Low Energy (BLE) Tutorial for Beaglebone
bleuio Nov 29,2021
1. IntroductionThis is a simple example showcasing how to control a BleuIO dongle connected to Beaglebone Black using a python script.When running the script, it will first ask for the com port where the dongle is connected (usually ‘/dev/ttyACM0’). After that, the BleuIO will start advertising. Every 8th second it will turn on one of the onboard Beaglebone Black LEDs whilst changing the BLE advertising name to indicate which LED is on.We are using the Linux debian image: ‘OMAP3/DM3730 Debian 9....
