Arduino Jobs

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.

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.

We want to use a arduino to control a ebike motor controller. We want to use various signals from sensors such as brake levers,throttle and pedal sensor to output a analog signal in a range of .1 up to 3.3 volts.

I have a 1970s Pioneer SX-626 stereo receiver that has some static in the left channel. I'm guessing some transistors need replacement.

We are developing second release of EntiaLiving Smart Home Sustem

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 someone to send data to an LED panel. - The driver being used in the hardware is mbi5124gp.

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.

I need to make mini geared stepper motor do one 360° turn Need to have screen showing timer and be able to adjust time in minutes example : Do one turn every 5 minutes

I need someone that has knowledge of this, to draw a graph from serial input which will be from an ADC on the MCU and given to the communication port via RS232. I should be able to save this as a CSV file and open it later in excel and the software itself. Software must be able to give me pane view and compress view. Deliverable is source code project file.

To develop a embedded c code for getting data from 8 ADC channels of stm32f103c8t6 controller and transfer the acquired adc data over modbus rtu / rs485.

Hi all, I need to write data from an RS485 device to a Webserver through the device Usriot TCP232-410s. I have a RS485 sensor connected to this device, and I want to write data in a database in my server. Is important to know how the device works:

Hello please bid for my esp32 project . let 's talk via private chatting.

This jobs consists of creating a YouTube video to show off our product features. The product is an electronic board that provides analog to digital conversions for the Raspberry Pi. It is programmed with Arduino and communicates over WiFi using the UDP protocol. The video must be between 5 and 20 minutes long. They must show screen shots of the codes, pictures of the product and hands on situations. The pictures provided are only examples. The person must have good knowledge of electronics, Arduino, Raspberry Pi and of video creation, video editing and picture editing. The voice can be electronically produced. Additional information can be found on our web site

I need to build a prototype with Arduino Nano of a multiple video night vision and pir sensors transmitting to a receiver with a High definition small touch screen when the sensor is triggered and I can switch from the receiver the view of the single camera I want. 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...

Arduino code for machine using 5 ultrasonic and 5 servo motor and lcd screen and keypas

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]

Looking for Arduino, Rasperry PI code, bootloader experienced engineer

Hi. I need to get a Raspberry device to set it up for my car. Can you supply me with the device and its setting. It's the best thing for me. I give you the link below where everything is well documented. Apparently it's easy but I'm useless in IT. Thanks for your feedback. The person need to be in London for delivery nd setting.
