Hi I hope someone can help. I am working on a Judge Dredd (Dredd 2012) costume and want to do the Screen that is in the gauntlet playing a looped video with sound.i am totally new to this kind of thing and i came across this tutorial using a 3.5" Nextion display. I have ordered the display but i need help in how i power it up and connect to the PC the or dont i need to connect to the PC is everything on the SD card then put in the screen ?Sorry i just have no idea, power wise what voltage can i use and like I say most important how to wire it up ? This is the tutorial link https://electronoobs.com/eng_arduino_tut145.php
In this tutorial STM32 MCU is used to interface PCF8574 Pin Expander over I2C to control 8 LED sound level indicator using only 2 pins. Both hardware and software are explained in details. All tutorial materials are shared in the GitHub Repository
This module for this post is a coin selector used for those redemption games machines. This can work with pretty much any type of metal coins all around the world. So how does it work? Inside we can see some infrared sensors, some copper coils, an electromagnet, operational amplifiers and a microcontroller. How can this module make the difference between several types of coins using those components? They are quite precise and the working principle is very interesting and involves magnetic disturbance. Well, in this post I will try to explain you how they work and make some homemade tests for each step. So, let's get started.
In this tutorial, STM32 micro controller is used to implement the algorithm used to trigger several different events, which are single press, double press and held pressed, form one single push button is explained with the necessary measurements that the code is based on.
This tutorial is a continuation of "STM32 Multiple Buttons ADC Read Through One Pin With Software Button Debounce" Tutorial, STM32 based electronic piano simple project was done using only 2 pins. One pin is configured to operate as ADC to read the status of 7 buttons and the other pin is used to derive a buzzer with a PWM signal. STM32 is programmed to generate a PWM signal with a different frequency when a different button is pressed, which will result in generating 7 different sounds. These sounds are actually the musical notes.
I've seen this idea on twitter and I wanted to make a homemade one. Is a nice product as humidifier but also as a huge smoking capacitor. You can 3D print it and make the same project with ultrasonic mist generator. Get the 3D files, the schematic and the part list from below and make your own. Consider giving me a like or a comment!
In this tutorial, STM32 MCU is used to read the status of 3 buttons using only one pin that is configured to do analog to digital conversion continuously to read the voltage variations of a voltage divider circuit over DMA. Software button debounce algorithm is also used in order to ignore false readings. The tutorial has detailed explanation of both the hardware and software needed for this application.

Necesito ayuda. Mi idea es poner los bms de 1s uno por bateria en 10 baterías (la batería conectada en sus pines correspondientes) y después conectar los bms en serie utilizando los pines de carga y descarga. Funcionaria para armar una bateria de 10s y controlar su carga y descarga? El bms que quiero utilizar es el de la foto
