Design Arduino Shield with code for RS485 and I2C and PC

Hello, I am an electrical engineer and expert in circuit design and PCB layout. I have been using Altium Designer for 7 years, I can submit you following results. - schematic circuit design & BOM - PCB layout, gerber, drill, PnP, 3D STEP files - circuit simulation if you want - 3D enclosure design ... Eagle, KiCAD, Protel, Allegro are all possible ECAD for me. Looking forward to having opportunity to discuss on your project. Thank you.

Before Awarding to Anyone give me a chance & kindly discuss your project in detail with me.. I am embedded system electronics engineer and expert in raspberry pi. I have worked on home/building automation with indoor positioning system, smart hydroponics system, etc. I have also worked on is women saftety device, on which, if women press the button, her location is shared with her family members and it starts recording audio to a cloud server automatically, while at the same time it calls nearest police station automatically. Please consider sending me a message so that we can discuss this further

Thank you Anthony

Hi There, We will design, built, test and ship the device. We will built the computer application too. Please feel free to contact us. Best Regards, Shahbaz.

Hello! I have some questions about the project description. If you could show me a block diagram of what you want I'll give you an accurate budget and delivery time. I have enough experience (more than ten years) in analog\digital design and PCB layout. Please contact me by chat if you are interested in my service. Regards

Aoa, Mr. Zuhair i have placed the bid with 1000Usd just as we agreed. Please award the project so we can start the work at the earliest. THANKS.

hello,how are you. i read your bid carefully. i am c/c++, arduino/rs485 expert and have full experience for 10 years. c/c++, arduino/rs485 is my top skill and i can handle your project by using that skills. i can provide most quality and high speed. if you want to success, please contact me. Then, I will give you good result to the proposals. hire me.

I want to work in this project. I have experience on Arduino UNO/MEGA to build any kind of Digital device to read sensors data and send it to the web server or process. Have knowledge on C and C++ to build console application for Windows. Have more than 15 years of experience on Digital Electronics.

Hello, I think I can help you, your description is quite detailed, thank you very much, but I am sure that we will have to define a few more details. I have extensive experience in Arduino, programming and PCB, in that I am an expert, but the expert in your business is you and therefore you understand better what you want to achieve and what will make you feel really satisfied, I want to understand also for help you to achieve it if you allow me to contribute with my experience. By the way, please tell me about my bid, maybe I can improve it if we do business.

Hello sir I checked your required Arduino shield features As you see at my profile,I built many different Arduino shields So I can make it for you from scratch to end I'll design the shield and it's software farm work I have proficiency in following software tools: Electrical circuit design Arduino IDE pcb design microcontroller programming ,interface plc programming scada system design Siemens S7 programming Electrical circuit simulation thermal control system building circuit (low energy control) bluetooth NodeMCU programming IOT (internet of things) Mplab(x) IDE micro C IDE PCB manufacturing Thanks Feel free to contact me for more discuss

Hi, I'm experienced embedded firmware and hardware developer. I specialize in wireless communication (BLE, WIFI, 3g/4g, LoraWAN, Sigfox, Zigbee, Z-Wave) hardware and firmware. I can design the boards and code drivers and business logic in embedded C. Recently I've developed fully certified Sigfox based IoT product for another customer so I'm familiar with the whole development flow. I also routinely use 3/4g modems from Quectel and Simcomm in my designs. Let's talk more about your requirements to see how I can help. I'm experienced in PCB design. I can draw this in EagleCAD and produce Gerber files for fab of your choice. I can also assemble a few prototypes and write firmware for them. I am also an expert in miniaturization, you can meet for my portfolio and Smablo project I've done designs that were mass produced for examples see Smablo project in my portfolio. All Smablo components were mass produced based on my design and assembly documentation As a part of my usual services I provide complete mechanical documentation of the design including 3d model of assembled board. As for PCB design this is a part of my service package. In my experience spiting project between drawing schematics and routing boards leads to subpar results. I provide the following: * establishing project specification * selection of components * electrical schematics * PCB layout and Gerber files for the fab of your choice * assembly documentation * 3d model of assembled board

I have made projects like this and have prior experience in the modules which are to be used in the projects. I will complete this project on time as said. So please provide us with this project.

Hi Dear, I am an Electrical Engineer with specialty in Embedded systems. I have been working on arduino boards for a long time now. And I would like you to know that I am developing a very similar board for myself with the use of I2C for communication between arduino boards. I can develop the complete project for you since I have knowledge of all the pre-requisites you mentioned for the project. I have designed communication applications between controller and PC in the past too. Please contact me so that we can discuss and get going with the project.

Hey. My team will develop software and hardware for you in accordance with the terms of reference Write to me and we will promptly develop your project.

i am four year experienced embedded developer, i have done many projects like iot projects, i am experienced in microcontrollers like pic,arm,arduino, atmel,atmega328p etc and c programming. used tools like orcad capture ,mp lab, avr, arduino, keil, etc. communications lilke uart, i2c,spi, wifi,bluetooth, rf etc. moudules like esp8266, lcd,glcd,gsm,eeprom,various sensors etc.

Comunicación bidireccional rs485 con módulo max485 y pc con adaptador ttl y microcontrolador, entrego códigos fuente. 9600 baudios.

Bonsoir,j'avais des competences et je peut vous aider avec résultat efficace.

Im not a fresher in this field And working as R&D Engineer in the Automation Development segment I can handle this task in very very productive manner Relevant Skills and Experience Im a senior Research and Development Engineer i can make it as per your choice. Allow me to show my skills

hi, I will develop the project within 15 days. I will then order the parts and test a physical prototype before the final project delivery.
