    I need to communicate between two arduino Uno using Modbus RTU. One Arduino Uno as Master and another as slave. Need to use Max485 module with standard Half Duplex protocol. Need Complete working Master and Slave libraries. And also arduino code for both Master and Slave such that Slave will change one register value. And that address read in Master. Similar, read digital input pin value on or off from slave into master. Also, master can control output pins of slave arduino.

    I want to have possibility to change CID number on any SD card. The goal of the project is assemble device or hardware which can change the CID number of any given SD card. It can be Arduino or combination of hardware (PCB) and software - it doesn't matter. The project will be closed when I will see that device or hardware can changes a CID number of a card that I will send to the developer. P.S: You do not need to suggest a solution for Samsung EVO+ SD cards because I already have it. I need solution for any SD card.

    Basically, we are making a project using Arduino Uno and Gsm sim900A module, LCD Display(LM016L) , IR sensor 1)Instead of typing a fixed password we want to send the password(4 digit) as an OTP to the registered mobile number. 2)There would be a mobile type keypad in which if the user presses the hash button it would send an OTP to the registered mobile number. 3)Now , when we receive the OTP we will type it on the keypad and when it is verified it will switch on a motor(Door). 4)Security feature is that it should allow only one person to enter in one verification. If , more than one enter it should send an alert to the Registered mobile number. WE HAVE ALREADY TYPED THE PROJECT OUT BUT THERE ARE SOME DEBUGGING AND CHANGES WE ARE NOT ABLE TO DO. WE WANT IT RECTIFIED AS MENTIONED ABOVE. This is for our engineering project. WE WANT A PROTEUS SIMULATION TOO OF ALL THE GIVEN SENSORS AND MODULES.(Mandatory for our project) the Proteus extension file to be sent. EXCEPT THE IR SENSOR WE HAVE EVERYTHING SO PLEASE SUGGEST US AN IR SENSOR YOU WOULD BE USING. We'll send you the code soon. :D

    This project involves navigating a vehicle through a minefield by using audio beacons of fixed frequencies located throughout the field. The vehicle will start at a fixed location in the field. The mission is to locate the “next” audio beacon and steer the vehicle toward that beacon while monitoring for the next beacon. The vehicle should continue to search each consecutive beacon until the final beacon is located, indicating the vehicle has exited the minefield. During the journey, the vehicle may not collide with any of the beacons and must steer clear. Vehicle Details: The vehicle consists of an aluminum chassis with three wheels (one front center wheel, two rear wheels). Each rear wheel has a dedicated DC motor used to motivate each wheel independently. Both DC motors are connected to a PWM motor driver unit that controls the RPM of each motor independently based on a 2 PWM signals. The details of the PWM motor driver are included in the appendix. Microcontroller: Teensy 3.2 Real Time processor: This microcontroller will interface the PWM motor drivers on the vehicle and the microphone sensor (and any other sensor you may include). Plan to power the vehicle separately from the microcontroller. A four bank AA battery pack is sufficient for the vehicle, while a separate power source may be used for the controller. Do not power the motors through the microcontroller; it is not capable of providing sufficient current. Battery packs may be purchased from [url removed, login to view] or adafruit.com. Sensor Details: The microphone/amplifier assembly is described below. [url removed, login to view] Beacon Information: Each beacon is a piezo buzzer tuned to a particular frequency. Details of the buzzer are below: [url removed, login to view] Rules: 1. You may use preassembled libraries for PWM signal generation and audio processing. 2. One group will be tested at a time. The vehicle will be placed at the starting point, and the beacons will be turned on. There should be a “Go” button on the vehicle to start the journey to the finish line as well as a visual indication (LED) that the journey has ended

    We have a custom board similar to STM32L476 Discovery Kit IoT, which already has Amazon FreeRTOS ready to be used. The original board by ST uses a WiFi module ISM43362 by Iventek connected to STM32L476 by SPI but our board uses a ESP-WROOM-02 (ESP8266) instead, connected by UART in this case. Our board is based on a STM32L476 but with different package. Tasks to be done are two: 1.- To replace the wifi library originally developed for the control of Iventek ISM43362 wifi module (connected by SPI) by a new librar for the control of ESP8266 connected by UART (in our case: USART2, pins PD5 and PD6), includding calls from aws_wifi.c or from other parts of the code. The task, so, implies full development of such a new library for ESP8266. 2.- To change the default I2C port in the Discovery Kit (I2C2) to the one we are using: I2C1 (pins PG13 and PG14) More info on attached files and following link: [url removed, login to view]

    We are a manufacturer and seller of egg incubation products. We are re-designing a thermostat controller for an incubator. We worked with a university senior class design team and mostly completed the project. However, now their class has ended and we still need to finish the project. We need an engineer with expertise in I2C and experience with PID controls. Thermostat and hygrometer sensor experience will be a huge help. I have attached a document written by the design team which explains the project, what was completed, and most importantly, what is not yet completed. Please see the document and especially the page which shows what still needs to be completed. We have all of the project and design files and documents that will be needed to finish this project. We also have an original prototype that was produced by the team. Please review the document and let us know if you are interested.

    I know only very basic stuffs about PIC. I want to learn more. You have to teach me PIC Microcontroller. Weekly 5-6 hrs and we can discuss it. I do have all the development boards. MPLAB and all the necessary things. I want to learn it in C , but not in assembly language. I prefer Skype or any other online platform.

    As project says it should be a PWM rectifier, drawing active power from the grid. It does not have specific requirements like power specification or so. IGBT can be used or MOSFET's. As PWM can be used any PWM with PFC. Only the schematics interest me. The PCB I will make it myself.

    Conceive SDR GnuRadio blocs 4 days left
    VERIFIED

    This project aims at conceiving GNU-Radio blocs for receiving / transmitting modulated radio messages using Software Defined Radio (SDR). I need a software component lib called "gr-beaglesdr" of a software-defined radio receiver and transmitter combined with suitable hardware device BeagleSDR. It can be used to listen to or display data from a variety of radio transmissions and also send waveform. "gr-beaglesdr" should support most of common features like CRC checks of the payload and header, decoding channel in real time... This library will primarily be tested with BeagleSDR as receiver and as transmitter. There are both AVR, FPGA, SDRAM, ADC and DAC inside BeagleSDR. You would be provided a sample of BeagleSDR board, however you need Beagleboard-x15 to start working in this project.

    Bit stuffing is the process of inserting non-information bits into data to break up bit patterns to affect the synchronous transmission of information. For a serial sequence 10111110; a stuff bit '0' should be added after every 5 consecutive 1's and vice versa when there are consecutive 0's
