    I created a Code for a Wallbox, so that Hotel Guests are able to use their Hotel Room Cards to start a charging process. The Code basically checks the validation of the Room Card, reads the Room Number of the Card, and transmits Room Number and the authorization to the MQTT Server. The Charging Station does the rest and sends an Email at the End. The Code works, but I have some hickups with collecting the mqtt Data of the current charging Rate and total Amount. Now I thought if it would be possible to use it with Tasmota, so I would be able to edit the Script from Remote, and don't have to flash the pcb onsite if changes are needed.

    Arduino Mega project with LCD 6 days left
    VERIFIED

    Hello, I have a arduino mega project with LCD, initially which was started with arduino uno and rotary encoder to feed commands. But now we want to upgrade it to arduino mega and LCD. We already have a code for the same and want to debug and add all the required codes and make a perfectly working model as per our needs. One should be very thorough with arduino mega and GUI design on LCD for the project.

    This is re-posting of an earlier project with refined requirements and specifications. The project is a c++ XIAO embedded system which reads the IMU, PDM microphone and a future MS58 pressure sensor. The project connects to a iPhone using five BLE characteristic for data and control. The code will use public Arduino and nRF52 libraries. The client will add the MS pressure sensor the to project after acceptance. The client is a developer and will be able to assist and help debug. It is preferred the selected developer also code the matching iOS app using Xcode and SwiftUI. The iOS app connects to the XIAO as the central and is the display device for the data collected from the XIAO. If you are available to immediately start this project please request the SOW.

    I need a test program to communicate between ESP32 (Sender) and STM32FO30F4P6 (Receiver). Please NOTE that the freelancer MUST test program using the EXACT model of the STM32 above via RS485 protocol. The code to send can be 4 digits long. On the receiver side, you can display SEQUENTIALLY 4 LEDs starting with PA5, PA6, PA7, and PA9 based on the code you send. For example 1000, 0100, 0010, 0001. That way each LED blink ON/OFF based on the information received. DO NOT SEND hex files UNLESS you are using the exact STM32. I have included the design files for your information. The winner is determined by DELIVERY SPEED and successful result. All files for STM must be written so that they can be imported via STM32Cube IDE. ESP32 file (Arduino IDE)

    I need to develop pressure sensor based coding for ESP32 mcu. Here, I am planning to use US9111 pressure sensor with mcp3421 ADC converter. I want to measure +5PSI to -5PSI pressure value, with auto zero calibration. When there will no pressure on the pressure sensor that must be zero value at the initial condition. It should be strictly maintain. It can be set by auto zero calibration. I want to measure pressure precisely, so you need to do the coding with exact calculation.

The project should include the code for the transmitter and the one for the receiver and the stl file for the 3D printing of the trasmetter and the receiver containers. The transmitter container should be as small as possible, considering it needs to support a small battery and transmit to long distance with the best quality as possible. Mini usb rechargeable and mini solar panel included to recharge. The receiver should be as thin as possible and it should have a thin battery both transmitter and receiver batteries should be...

    There’s some things I didn’t specify in this drawing. The esp8266 has 15 pins on both sides, The lcd adapter has 4 pins to the left and 16 pins at the bottom. Then I’ll need another 16 pin vertical female header for the lcd screen (pin 1 from the adapter would need a trace going to pin 1 on the lcd adapter board, 2 with 2, etc.) As for the components I’ll just need holes so I can solder them. I’ll just need it printed as for which hole is which. [Removed by Freelancer.com Admin]
