Arduino Controller. On-off valve servo position based on max and min temperature measurement.

Hello Irving, Thank you for the additional project details. Total hardware cost will be less then 35USD from ebay. If you use ethernet shield for arduino then you can access your system via webpage from iMac. You can see the sensor values as well as you can set the constants/parameters. Waiting for your reply. Thank you Sam

Hi, have a nice day. We are team of engineers running an Electronics company. We will fabricate the prototype in our Lab and arrrange the demo. Once every thing is OK we will hand over the Design files. Following will be deliverable from our side. 1. circuit diagram (schematics) 2. PCB layout and gerber files 3. Arduino Sketch 4. Bill of matetrial. Please let us know about the temperature range. All of the design work will be carried out in Proteus and Arduino IDE. We will ship you fully working prototype. Just for hint, we will be using PID controller. Looking forward for the response. Please fel free to contact Best Regards, Shahbaz.

Hi, I have experience in Arduino developing - sensors, steppers, servo, networking, data processing. I can do your project. Best regards, Slavi.

Hello! I have a wide experience in Arduino development. For more information please look at my completed projects and feel free for any questions. Thanks!

Hello! My name is Bogdan and I have wide experience in embedded systems developing. Your project looks not complicated for me, so I can provide good and cheap solution for you. Could you provide more details about the project: values of Tmin and Tmax, preferable temperature sensor, detailed algorithm etc. I have finished also some similar projects recently. We can discuss your project if you are interested. Regards, Bogdan. UPD: Hello Irving! There are few possible ways to make your controlling system. Yes, you can use DS18B20 as a temperature sensor. Hardware solution shouldn't be complicated. I can help with that. Did you have the servo valve? I can make such system for you and send it by post. I can implement some external interface also (web, usb etc). But I need to discuss the project for final bid defining. We can discuss it by chat. Hope to hear you soon. Regards, Bogdan.

I have the servo set up and the Arduino, the sketch will write you can easily download on the system you buy and tune it. I will also guide you in theory,practice and implementation of hardware. Cheers: Adi

Hi, I read your project description. According that a servo valve should be controlled using temperature readings. I can help you with this project. I have done several projects using Arduino some of them includes multiple servo motors. You can contact me for further clarification. Regards, Akilan

Hi. I am a professional Electronics Engineer having expertise in Electronics Control circuits as well as in Arduino programming. Contact me and get a perfect code. I need to ask some questions to you too.

I am an expert in arduino and embedded programming. I can do this project for you at competitive rates

The following program will be done in the required time frame and coding will be provided with in three days . from monday onward .

i have good knowledge about arduino programming and have done number of projects using arduino,i willl do your work easily and accurately as soon as possible

Hello, First of all I would say that this is a very simple and straightforward project and that it will require less than 40 Euros to develop. I will develop this project's algorithm, write code and if required also make the schematic, all for 30 Eur (34 Eur with freelancer fee) Waiting for your Answer.

Hello, I am a Hardware and Firmware Developer cum Schematic/PCB Designer, having 9+ years of experience. Expertise in Arduino, AVR, PIC, 8051 programming. PCB/Schematic design expertise in Proteus, Altium, Eagle, Orcad. Also having expertise in using Simulators like Proteus, Multisim, PSpice. So, I can simulate this project in few hours. And if u want some changes in the result as per your specific requirement, it can be easily done. I want to discuss further details. Thanks Sapna Surve

I have ample experience working with Arduino and basic to moderate electronics projects. I will most likely be able to deliver within one day.

Hello! I can help you with your project. Being an automation engineer, I deal with this type of projects every day. Give me a chance on this project, and if you like we can become partners for industrial / non-industrial automation projects.

Hello, Please, indicate the specific Arduino kit. I accept AVR microcontrollers. I'll provide source code and other files after full payment. The firmware will be developed in AVR Studio. The project seems more complicated after addition of the description. 1-wire digital thermometer requires sophisticated control logic. Do you consider NTC resistors or not? They would be cheaper than DS18B20. Do you need a LCD display and RTC (Real Time Clock) chip too? That is possible. I would suggest a COM port to connect the device to your PC. It is cheap and easy. We usually use USB/RS-485 converters to connect PC and devices. PC software sees the port like COM. It is a virtual COM port. We completed a long-range Bluetooth based project some time ago. But Bluetooth is more complicated then COM port. It is difficult to tell the exact price of the device. Supposedly, the ballpark figure will be up to 50 EUR for 5+ units excluding USB cable. We usually buy components from Mouser or Farnell. How many units do you plan to produce? If you need many devices, then it's worth to reduce component price. Best regards, Vitalij
