STM32F1 Blue-pill: WiFi shield (WiFiNINA)
Mischianti Aug 22,2022
First of all, read the article “STM32: use WiFiNINA with ESP32 WiFi Co-Processor”, where there are all the basics to understand this shield usage better.For me, It’s very important the network connection and network limitation on STM32 It’s very tedious. Adafruit offers a solution, but I think that a shield It’s more usable.So I design a shield to add WiFi to my STM32F1 blue-pill.PCBThe PCB is quite simple, I also add an interface to update the firmware over esp32. Strangely, esp32-s seems ...

PCB_PWM-Fan-Controller-with-RE
MakerIoT2020 Aug 22,2022
Last month I spent quite a lot of time on expansion modules for use with the ESP-12E I2C Base Card. While the system worked exceptionally well as a prototyping and firmware testing platform ( as originally intended ), I immediately saw that the physical size of everything ( base board, with the cards) would be a problem inside any enclosure, when used with a real-world project.At the same time, I have an ongoing need to design and manufacture a device for a friend, that will have very limited sp...

MIDI Breakout Board
Lunde Aug 22,2022
When I first started out with building the BulkyMIDI-32 (running mt32-pi), I had no idea what I was getting into and of all the modules I started building - this is the one I wish I'd started with. It was designed for use with Arduino Uno, Nano, Every and Pro Micro in their 5v variants - mostly because these are what I'm most familiar with. What it gives you is the circuits for adding 5-pin MIDI IN and OUT to your board using four cables.

Lora Communication With Network
electronicguru0007 Aug 21,2022
This was a very simple project and can come in handy for various applications. But what it can't do is establish communication with the internet for modern-day IoT applications. So in this project, we will be using the HPD13A which is a SX1276 IC-based LoRa module to establish communication with the things network, so we can use this module for IoT-related applications. So without further ado let's get right into it.HPD13A - SX1276 Based LoRa Module PinoutThe pinout of the HPD13A - SX1276-based ...

Remote Servo Actuator
Iturriaga Aug 20,2022
How does it work?The ESP8266 board (D1 mini) connects to the wifi your wifi network and the Blynk app. When a Botton on the app is actioned, the ESP sends it to the servo motor. The LM7805 transistor is used to convert the 9 volts from the battery to a useable 5 volts. All of the parts used are widely available for some cheap prices.Building and Programming:Building the Blynk app:Start a new project on the Blynk App.Name it Remote Servo Control, choose ESP8266 as the device and choose the connec...

DIY Aduino One Axis Self Balancing Device
Pavleski Aug 20,2022
 This time I will show you how to make a simple One axis self balancing device, which is based on the PID control system. A proportional–integral–derivative controller is a control loop mechanism employing feedback that is widely used in industrial control systems and a variety of other applications requiring continuously modulated control. A PID controller continuously calculates an error value as the difference between a desired setpoint and a measured process variable ...

Tiny ML Air Writing Recognition with Nicla Sense ME
AlexMiller112 Aug 19,2022
StoryLess than half a year ago, a new Arduino’s board, Nicla Sense ME (Motion & Environment), hit the market. And, needless to say, I couldn’t wait for a chance to try this brand new device and explore its capabilities.Nicla Sense ME is currently the smallest board across the entire Arduino PRO family of boards for industrial applications. It comes with a range of Bosch Sensortecsmart motion and environmental sensors, and I’m quite sure that this device will be widely applicable in industria...

MacTEMPtosh
Arnov sharma Aug 18,2022
Greetings.So this is the Mini MacTEMPtosh, a portable Temperature and Humidity meter that displays the current Temp and Humidity level by an onboard AHT10 Sensor.Its Body is made to look like the old MACINTOSH 128K Desktop PC so that's why it's called MacTEMPtosh.This setup is powered by an ESP32 Board and has a Lithium Cell as the power source.AHT10 is being used to measure the current TEMP and Humidity level that is being displayed on an SSD1306 OLED Display which is all control...
