    I need an Arduino program and a Java client. The Java client will send a String to the Arduino server and the Arduino server will echo the string back to the clinet. I need both the Arduino C++ style script as well as the Java client code. I will pay more for people who are skilled and can do it quickly/ preferably have working code already.

    I have firmware for an ESP32 device written for PlatformIO (basically arduino), but it has become very long and messy. I need help removing any redundant functions that are not being used, and creating a library with all the remaining functions. This will alllow the file to be less cluttered as it will call its functions from the library file. The ESP32 firmware controls a device with an ADXL accelerometer, an optional GPS unit, ethernet or wifi connectivity, LEDs and a buzzer. After starting up its peripheral devices it checks if ethernet is connected, if not it uses Wifi with Smartconfig protocol, then connects to AWS. This is done using AWS certificates stored in the SPIFFS memory. Once connected to AWS it collects the ADXL FIFO buffer of accelerations every second and sends them t...

    Smart Weighing Scale 6 days left
    VERIFIED

    Looking to build a simple smart weighing scale. Features required are - - Device should be small - shape & size of a coaster (circular, but not very thick) - Should be cheap to make & easy to replicate - prototype can be around $10 - $15, but if it needs to be mass manufactured, we would need to do it around $3 - $4 - Device should be battery powered (flexible on battery capacity, based on cost) - ideally rechargeable battery - Maximum weight expected would be 1 - 2kg - Require precision of 1g - Device should have a button, which when pressed sends the weight data - Device sends data to a web API / via Bluetooth (either is fine)

Below that it convert to a low tilt vehicle that can dynamic level as it crabs around at this speed compensating for rolling tilting surfaces like driveways and pot holes. I have developed a lock or and drive actuator. I can manually controller. I am using an analog electrolytic tilt sensor used in farm equipment and motor homes to level them. I want to switch to Arduino for better control of functions and debugging.

    It's needed to make the script that will: 1) make a photo each second from connected USB cameras (3 pcs) and save this photo in a specific folder (separate folder for each camera: camera 1, camera 2, camera 3). The name of the photo will be the time of its creation. 2) automatically start with Jetson Nano start and will automatically turn off after an external power cut (I'm using UPS, so we can see external power voltage and battery voltage). Jetson nano must start when external power appears. 3) Video from the camera must be shown on the display. The display must be divided to show video images from each camera. Remote access to the Jetson Nano - AnyDesk.

    The aim of this project is to create a scanner that measures electrical impedance on the skin (Magnitude + Phase shift). The hardware that i am going to use is: USB-2020 DAQ, Universal Screw Terminal (37-pin), Arduino, SparkFun MiniGen signal generator. The software that i am going to use is: Labview 2019 SP1 I need a freelancer to help me build my acquisitioning circuit and develop the LabView software to operate it. The logic behind the circuit is, we apply some voltage/current on the skin and measure the impedance of that area as a response. We then do the necessary calculations and print the results on the screen in Graph form, Nyquist plots and (if possible) some type of spectrogram. Hardware should be placed in a black box and operated exclusively through software.

    Il progetto prevede una configurazione hardware già definita parzialmente con scheda controller+rfid+wifi+schermo touch oltre a modulo di alimentazione da definire. Il software dovrà prevedere la lettura di card rfid e inviare i dati della card ad un server. I dati sono riferiti ad articoli da ordinare semplicemente avvicinando la card, ogni card corrisponde ad un articolo. Il software dovrà inoltre dare la possibilità di inserire la quantità ordinata dopo la lettura della card e vari messaggi di conferma o errore. Dal lato server i dati dovranno essere ordinati per cliente, articolo, quantità (dati presenti in ogni card) Lo spunto lo prendiamo da questo progetto pubblicato :
