STM32F1 blue pill EByte LoRa E32 E22 E220 shield v1.0
Mischianti Aug 12,2022
Full documentation of the PCBEByte E32 tutorialEByte E22 tutorialEByte E220 tutorialI start using STM32 microcontrollers, and I find they a superior quality. But I need some prototyping board to do my work faster.So here is a prototype board to develop the LoRa application. As usual, I use EByte modules, and this board is fully compatible with E32, E22, and E220.More information, BOM, and description on the relative article on the site.STM32F1 pinoutAs you can see in the pinout diagram, you can ...

Real-time Smoke Detection with AI-based Sensor Fusion
Aug 12,2022
AttentionThe following project is just a DIY project and did not replace certified smoke detectors. As I'm a voluntary firefighter, please keep your home safe and use high-quality certified smoke detectors. The sensor system which is developed by this project is only an addition.BackgroundSmoke detectors save a lot of lives. For example, the number of fire victims fell by more than 48% in France from 1982 to 2012 and 56% in the UK from 1982 to 2013. These reductions can largely be linked to incr...

ILI9341 Display and LOLIN D32 Carrier Board
Arnov sharma Aug 11,2022
Greetings.So this is the Carrier Board that is basically a connection board for connecting ILI9341 Display with Wemos Lolin D32 Pro Board.The goal for preparing this project was to make a setup for connecting the display with the ESP32 board without using wires and a breadboard for preparing display-related projects.This board serves as a replacement for the breadboard setup that we do for connecting the display with ESP32 Board.This Article contains the built process of the Carrier Board along ...

Smart Basketball Scoreboard
Ávila de Oliveira Aug 08,2022
IntroductionI do basketball training workouts regularly and always track the sections' statistics (number of shots, scores, misses, etc). Track these numbers is kind of boring and hard to accomplish. The smart balls can be used for this but they have some drawbacks:If you want to train with multiple balls you'll need to buy several (expensive) smart balls.The accuracy isn't so good.The durability of the ball.Let's go for it!Versions1.x.xAt the beginning of the project, I used the hardware compon...

SmartWristband
Andrei Florian Aug 07,2022
Abstract Figure 1: The SmartWristband device being worn Monitor patients sent to self-isolate with the coronavirus by collecting their temperature and heart rate through a comfortable wristband and sending this data to the hospital through an interactive dashboard and ensure that they respect the isolation by alerting appropriate authorities if the user leaves their home. I decided to create a solution that would help care for people which have contracted a weak form of the virus....

Arduino Liquid Level Meter with simple Homemade Sensor
Pavleski Aug 06,2022
  There are many different ways to detect the level of water in a particular container. This time I will describe a way to make a sensor yourself, and then with the help of a microcontroller to accurately determine the level of liquid in the container. I will also show you how this level and its change can be tracked graphically on the PC monitor. Get 10 PCBs only $5 https://www.pcbway.com/QuickOrderOnline.aspx  To make the sensor, we need only a ribbon cable from old ID...
