    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

    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.

I have a 5v laser for Arduino and the sensor may get only a 1% or less of the intensity of the light. don't think if there is light around, the sensor and the laser will be inside a dark space. Could be awesome if you can use LTspice XVII to make the circuit.

You must also provide a basic Arduino firmware for basic interactions with the module. The jobs will be awarded on a per module basis but ideally the same person would end up making most of them. You must be experienced with Arduino and Altium.
