    Raj did a very good job researching the project and giving recommendations. This project included color touch screen programming on an Arduino board with 36 other inputs/outputs. He communicates very well in English and responds very quickly to inquiries. His programming was structured very well, and it was concise and well-documented. Make sure you lay out your project in as much detail as possible to him at first, and I'm confident that he will recommend a good solution for you.

    Please see the deliverable in the attached, basically its a simple work and i only require the arduino program code so i wont be paying alot as it is a simple work, but i will have more works in the near future. if we are able to have a good partnership we will work have more work together. my works will be simple but i will have quite a number.

    I need a circuit that monitors a thermostat. The thermostat is a 24vac line. The input will go into the ADC of a digital IO pin of an arduino.The circuit should use a consume a tiny amount of power off of the 24vac line, just enough to monitor it. A the output will need to be probably high impedance and interface with whatever the digital IO pin of an arduino needs, current sync or current source. The output will need to b 0volts or 5volts and have conditioning so it"s a nice clean signal.Thanks

    Hi,Thanks for looking! I"m not proficient with all of the terms used in this field so please be patient while I describe what I need. I need somebody who is efficient with C programming or better yet, someone who has experience with Arduino libraries to program a Arduino USB micro-controller with an lcd interface attached. The controller will output a 4 digit code to a text file (or input field) on the computer. It will also output this same code simultaneously to an lcd screen that"s attached to the micro-controller itself. The controller will start at 0000 and run until it reaches 9999. There are a few other simple conditions that need to be implemented such as:Hit enter after entering the 4 digit code. Wait 16 seconds until outputting the next code.Begin automatically a short while after it has been plugged in to the computer.I have the majority of the code ready for a teensy 3.0 but need somebody to tweak it so that we can output it to the lcd screen.I will purchase the Arduino and lcd attachment after consulting you and seeking your advice on the best one to purchase and await the code to implement it. If it"s more suitable for me to send you the device, then I may be willing to do that too. Thanks for viewing.

    I need you to write a simple arduino sketch like following : I am using an arduino mega + a 5" ITDB02 LCD board + a stepper motor 1- you need to use the library at http://www.henningkarlsen.com/electronics/library.php?id=51 and the stepepr library at http://www.airspayce.com/mikem/arduino/AccelStepper/classAccelStepper.html , with an arduino mega 2560 R3 board to display 3 buttons with some text on them - button 1 : Text = "+" , Functionality : Allows to increase the value of an integer variable in the sketch (let"s call it NB); - button 2 : Text = "-" , Functionality : Allows to decrease the value of the same integer variable; - button 3 : Text = "Go" , Functionality : Starts a stepper motor to do NB complete turns (i.e. NB * 360 °), and then stops Of course clicking the buttons is via touch of ITDB02.When one of the above buttons is clicked, it"s displayed iva Serial.print(..)I already gave you the libraries to use and the sketch is simple, so i expect this won"t take more than 2 days to finish and costs should not be more than 40$

    This project,is with regards to a fuel dispenser that we are having at our facility.What we need to happen is :-1) The fuel pump should run in two modes- A & B2) In the A mode all the deliveries should be proper. That means for every 5 liters, entry from keyboard, it should deliver 5 liters. But in case of B mode (which can be used if we press a code in the keyboard), the pump should deliver, only 4.75/4.80/4.85 liters instead of 5 liters, depending on the option chosen.How we need that to happen is :-The keyboard is connected to various other cards in the dispenser, and sends in signals for the operation to happen. What we want someone to to do is, change the program in the keyboard IC (or microchip), so that when alternate mode code is pressed, it sends in wrong signals (i.e. 90/95% of what is actual), so that a wrong delivery happens.We have the complete assembly of the fuel dispenser, which we can send to the freelancer. Along with it, we can send you a image of the laptop, which the company engineers use, to program the various cards. Also, all the manuals which the company provides the client, for usage.Regards,Sundeep

    I need a good freelancer for a fuel dispenser related project. We confess, that it is very complex project, but so is the price paid.We need the freelancer to make some minor changes in the calibration program of the fuel dispenser, with the condition that though it should dispense 4.80 lts instead of 5.00 lts (only 4.80 i.e. the amount dispensed from the pump, should be updated in the motherboard and seen, when checked through keypad but 5.00 lts displayed on the indication board).I have the laptop, which the fuel dispenser company people use to program the pump. It contains .mhf files for UIC,Motherboard and Backbone cards. We need someone to provide us a workaround (only software based, without any use of hardware).Do let me know, if you are interested. Ping me on sundeep_ballare at Skype.

On each stepper, I will attach 2 to 4 pygmies.For each stepper, wait a random time (some seconds) turn on the stepper counterclockwise or counterclockwise depending on noise detection.
