I need a python script that can run on audio files (wav, mp3, m4a, ogg, flac) with different sampling frequency. the function needs to output - a 0/1 value whether the audio content uses full band of the file sampling frequency or is band limited. - if band limited - provide the cut-off frequency where no more energy is present. - provide a 128-long vector (linear-scaled) of energy per frequency band (out of input sampling frequency). The function should work for inputs sampled at 16kHz, 24kHz, 36kHz, 44.1kHz, 48kHz and 96kHz. it should also handle typical audio resolutions (16bit, 24bit, 32bit + float) The function should down-mix the input to mono before analysing if needed. the function should only use code that can be used commercially without acquiring any additional licenses. Inp...

There are 2 tasks to do: 1-integrate a speaker using 2 options: I2S and analog 2-save the data from I2S microphone on sdcard on different wave file than the existed on the sdcard. Steps of the program: register sound with microphone ---> save the sound on sdcard .wav file ----> reproduce on loop the last file saved Initial code for I2S microphone reading and saving data will be provided. Code is made in Arduino - VScode

i have arduino code .i want to change same code or logic in atmel c micro controller.

Hi, I have built a circuit and there seems to be a problem with it. I am out of ideas what the problem is. Can you watch the videolink where I describe the issue and have a look at the drawing. If you know why this problem happens, I want to hear from you. The job is completed once you told me what the problem is, so it will be a "one msg" job :-) Thank You

hi looking for an expert on tritan mcu TR16F064............ thank u

Hello, I am kind of started on this one. Any assistance would be great. More details on the chat.

Analog Voice Recording/Playback Device. More details will be provided as needed.

I need someone to help me in my microcontroller project. Kindly let me know if you are available. Thank you.

Robotic arm from Ufactory need to program to receive order from kiosk and start working on the order required python skill and robotic arm experience who based in Sydney

Avrei bisogno di compilare un programma con relè 220 , qualche sensore che li attivi e poco altro

This is an Arduino-based project using MQ135 / MQ138 gas sensors to detect diabetes type 1 and type 2. There are tons of resources about this topic on the internet, but could not find the code. This is a personal project to help my diabetic friend

Ingenieron en electrónica con conocimientos en esp32 que desarrolle un cargador solar y una pila que almacenen energía para alimentar de manera continua a una placa de desarrollo esp32

Hi, I need a code to create Fit lights training with arduino. Those lights/sensor will light up and then light off when hovering with hands and then light up another light in the kit. Like 6 lights. I also need the diagram for the wires. tks Seby Something like that

Attaching an electric motor to a cart The maximum speed is the maximum brisk walking or slow running speed. Maximum load 100KG (Torque must be strong) I wish there were gears. D forward R reverse N Gear neutral (wheels move freely) Also works by attaching a button to the handle (requires programming) These are the details. I have uploaded a picture of my cart in the attachment.

The hardware i have is from Nordic series and it should be controlled using BLE. The script is preferred to be in Python. The led of the dongle should be turned on/off according to the commands.

Raspberry pi will be the brains for this project and connected to Arduino via i2c. Modules are multicoin coin acceptor, bv20 bill acceptor, tm1637 7 segment display (4 and 6 digits), mpr121 capacitive touch sensor for keypad, sd card, cnc shield (gbrl), servos Python, c++, sqlite (peewee orm)

Test and suggest pcb and equipment redesign to comply with emc regulations

I would like to get the TVout library to work for STM32F030. (with the Arduino IDE, preferably using the stm32duino boards manager ) I tried converting the ATMEGA library to STM but I wasn't able to make any progress (I'm a mechanical engineer, updating that lib was well beyond my capabilities) I also tried one from "" but was not able to get it to work/ it comes up with warnings/errors (some listed below).

I need Arduino code for ESP8266 or ESP32 that can connect to a wifi network with proxy settings and then post data to Adafruit. You can check out the code added. That's the basic code idea.

Esp8266 Multi Node Control without any delay

Hi! I am an embedded developer. I am working on a project "Indoor air quality Monitoring system". I need a circuit designed for this one. I will be using a microcontroller for driving various sensors. This product is in its RnD phase, as of now will requiring only a circuit, if the circuit works , will be requiring lots of them, will be ordering them accordingly.

I need a python script that consists of 4 functions: 1. move- to ( coordination in cm), 2. rotation ( in degree), 3. magnet up-down 4. and magnet on-off (by taking 0 or 1), 5. and must send values to Arduino R3( Communicate With Arduino From a Python Script) 6. I do not want to write anything in the python console 7. after sending data to Arduino we will get ok as an answer that Arduino gets these values. 8. I do not need Arduino code, just python script .for example I want to do the process like <mt pos_x1 pos_y1> <take 1> <mt pos_x2 pos_y2> <take 0> That means "go-to source position", "magnet down, on, up", "go-to target position", "magnet down, off, up" or sometimes rotation.

We need to look for Strain sensors suitable to measure the weight of the feed inside silos. We are looking for a manufacturer of this type of sensor in China. Load cells does not work for our project because they require a complex installation process. We are looking for sensors similar to ( - ) Our Silos are installed in farms to storage animal feed. They have 6-8 legs and have a capacity of 15.000 and 25.000 kilos. We need help to find this kind of sensor, get some quotes and make sure they would work in this type of application.

An expert with STM32 is needed. The expert must be proficient in using the required development board.

I have an IOT device which works on my hosted MQTT server need to have the same integrated with Alexa and Google Home

Proyecto de desarrollo de placas PCB con el procesador ESP32 para recibir datos via bluetooth y enviarlos por wifi a la nube de diversos dispositivos.

I'm looking for someone with experience in extraction using a USB rubber ducky device. I want to be shown how to work with specific payloads that can be used within a live demonstration environment, to showcase how quick and easy it is for someone to extract information from a PC/Laptop within seconds. The purpose of this is to demonstrate Security Awareness to a specific SME audience. Experience of such payloads using a USB rubber ducky would be essential.

Hydroponics system, Design pcb in easyeda using the ESP32 Development Board controller, and Configure the project ready to order shipping. programming in Arduino Program. program sensors, print real data obtained on screen and arduino monitor. ABOUT THE PROJECT: -The PCB board must be a support plate for mounting external modules or with additional outputs, components such as resistors, capacitors, connectors, modules, etc. They must be components of the most Universal possible. The objective is to make the project more efficient and thus avoiding cables. The total measurement of the pcb card must have a maximum size without exceeding the measurements 9x15cm. -The screen has a simple menu that displays the data sensed in real time and uses the encoder to modify parameters such as the time...
