Elaboración de un dispositivo capaz de bloquear la señal Bluetooth 2.4g con un alcance aproximado de 20 metros

Quiero armar un MPV de una caja con sensores en Arduino que haga lo siguiente: Medición de altura precisa, localización (gps), velocímetro y una cámara de fotos. Toda esa información la debe enviar a través de una señal 4G cada 1 minuto para poder ser procesada en un computador de escritorio en la oficina. Es un prototipo para la construcción. Nosotros compramos todos los materiales y deberá trabajar en nuestra oficina (Las Condes, Santiago de Chile). Solo presencial.

El objetivo del proyecto es generar un prototipo basado en Arduino y BLE 5.1 para la localización relativa de equipos (relativa entre el receptor BLE 5.1 de Arduino Portenta H7 y un smartphone)

hi, I have a device that is like a midi controler using arduino and usb cable to computer. I am looking for someone with experience in arduino coding, this code has a midi function that is working fine except there is some kind of note off error or another error that causes notes to be played when not asked. I need someone who can fix this code error so I can make my device nice and functional. this should be a easy fix if you know midi and arduino code. I have a small budget because this is my first project but I will order more jobs from you if I like your work. I would like to pay 5-10 dollars for this.

I want to build a BLDC Motor driver for 310V Motors which means a 230VAC Input. Basically it can be based on existing development kits (Infineon/STM/etc.). Example like this from STM: Please lets discuss which MCU and Software could be used to program different motor types.

I have a completed design for managing 2 low voltage lithium battery cells. Most of the firmware has been completed, code is available. I need to modify/complete the firmware according to the requirements/functions document. The deliverable should be a Simplicity Studio 5 project with all the files for downloading the firmware to the micro-controller using an Espressif USB debugger. Schematics, existing code and function description included in attached zip code Please review before bidding, only interested in reviewing candidates that have looked at the files and know that they can complete the project. Thank you.

More details will be shared via chat with potential freelancer

We developed custom brushless motors with generators for our octocopter drone. We need someone to order the parts, assemble them, build prototypes. If the motors need to be redesigned after testing, we need to assist in the redesign. The motors are one motor on the top and another one on the bottom. Our own motors integrate the top and bottom motors in order to reduce space. We want the ESC to be integrated into the motors. We want own foldable 30-inch carbon fiber propellers (3 Blades) with a snap-on locking system for easy removal. Our goal is one hour flight time with 30lb payload.

I would like to design a rotary spindle that can take loads up to 50kg, mounted on bearings and rotate them in a composites oven. Think BBQ bbq rotisserie. It needs to be able to have variable speed from approx 10rpm to 60rpm. It would have a simple LCD with menu to start stop pause, change direction and set RPM. It will use GT2 closed loop belt and 3d printed gears on the driven and driven gears. I am seeking someone to recommend the control board, motors, motor controllers, lcd and complete the software. Arduino with steppers motor and external stepper motor controller comes to mind, but am open to suggestions.

Needed: We're looking for someone to join our small team who is proficient in coding in Python, MicroPython, C++ or a similar micro-controller language in order to integrate an ESP32 or similar board with other hardware. Our need is to enable communication between commercial off-the-shelf hardware, firmware and software and then use Blynk, or a similar platform, to develop the machine-human interface. This is a drone (UAV, unmanned aerial vehicle) related project so a good familiarity with basic mechanics and dynamics is necessary. ArduPilot familiarity would also be advantageous, but not necessary. Multiple environmental and situational sensors will need to be integrated, so logical programming will need to be written to include these sensors and flight actuators (servo or stepp...

write a C program that interface together via a LabJack U3-HV. Purpose of this Design: Optical Sensor Alarm with Buzzer The purpose of your project is for a piezoelectric buzzer to sound on and an LED to turn on optical sensor circuit is interrupted. When the sensor is not interrupted, the green LED output will be off and the buzzer will be silent. When the sensor is blocked, the green LED output will turn on and the buzzer will sound on. The sensor state must be read and displayed to the user every 0.25 s, regardless of its value. Method 2: Exit program after 15 seconds of continuous running and monitoring. To test your project, run the code and trigger the alarm several times while the code is running to see the two outputs change states. The interface should conform to the specs lis...

The problem in Sensor Interfacing and Sending Sensor Data on Cloud : We have connected two sensors to arduino, and we want their data to be uploaded to cloud through RPi and the data of other peripherals altoghether like gyro, GPS 1st problem is : we're unable to send data from two sensors to Rpi through Arduino continuously as we're connecting them using a USB cable. 2nd problem is : the gyro connected to Rpi using i2c is giving timeout error after few seconds and stops the whole program 1. When we use Raspberry Pi board alone to connect all the Sensors ● We are connecting ADS1115 ADC Converter, LCD Display(I2C) and Gyroscope parallelly on the i2c Communication pins present on the raspberry pi board, Since LCD Display works on Lower Level Voltages so we have to convert that ...
