    Luis was very responsive and understanding of my project requirements. He was able to complete the project on time and at a very reasonable price. I will be working with Luis in the future as my project evolves. I would not hesitate to recommend Luis for programming needs. Thank you Luis for your help.

    Project Description:example: #include <Servo.h> #define DELAY 250 Servo testServo; int motorPosition; void setup() { testServo.attach(5); testServo.write(0); } void loop() { for(motorPosition=0;motorPosition<=180;motorPosition=motorPosition+10)...

    ok - i need to use some existing sensors in an unorthodox manner to create a much needed automation solution ... id do it myself but the hours i could spend researching are better off served by using a competent programmer .. i am absolutely certain of the manner in which this setup will function .. but i need somebody to interpret my design and get it done fast .. I"m not rich .. but i will offer stakes in the final product as well as some money .. as this really is going to be a fast seller .. actually - if you are the right person i have another design which MAY also turn a profit ... anyway ... I"m in the cotswolds in the UK .. I"m good to travel .. and i want to make a move right away .. but I"m a chilled person so easy to work with.

    Attached are the documents.1. AEC form 2013 is the form to be captured. We need to design an interface exactly like the form with "Previous" & "Next" buttons. We can use "Step By Step Wizard" of this template: http://www.themeforest.tzd-themes.com/?theme=Lagu 2. Migrate old data for all previous forms currently stored in Oracle database into the newly created database in 1. I will write SQL scripts to pull data for previous form per year into csv from the old databse so that you import it into newly created database in 1.3. We have then to generate reports that will export data to excel as in "EMIS Statistical Yearbook 2011.pdf" for "EMIS Statistical Yearbook 2013.pdf".TASK 1BackgroundCurrently, there is java web application build on top of Oracle database for capturing an old version of the AEC form for 2012 (I attached below the AEC form for 2013). This application does not have all the fields of the AEC 2013 form as they were few that were recently added. Work to be doneWe need to add the missing fields on the java web application forms to accommodate new fields. I will indicate later the all the fields missing.TASK 2BackgroundPart of the AEC 2013 form, there are grayed fields that will need to be pre-printed. There is currently a PHP web application build on top of Oracle database that was doing this work but not doing it properly. To be doneWe need to re-develop this pre-printing application either using Java or . Net or PHP so that it can do the pre-printing. We can re-use the SQL Queries being used by the current application.NOW for us to understand all the requirements, we need access to these applications and database. I have had access to the Oracle database in the past and I understand it. 1. You and your team need access to the server so that you can see how this java application can be changed to accommodate the new changes.2. You and your team need access to PHP application to see how it is doing pre-printing.In order to do 1 & 2, we have to find tools to connect to the server as it cannot be made available outside. I can put my 4G Internet dongle to have the server have Internet and maybe we connect using tools such webbex, etc.No Choice for DB : I must need oracle as DB. and I want task-1 first.

    I need to calculate the distance, in cm, travelled by the IMU over multiple one second intervals.I need you to:Read and understand the Adafruit unified sensor readings API and understand how it works and relates to the 10-dof IMU - https://www.adafruit.com/products/1604This is the breakout board I am using and the connections I have set up:https://learn.adafruit.com/adafruit-10-dof-imu-breakout-lsm303-l3gd20-bmp180?view=allWrite a piece of code in C, that will run on an ardunio mega, that calculates the distance travelled along each axis every second over a twenty second period.The results from each axis should be stored in an array with 20 slots.In addition, the sketch will print out each second to the serial monitor the distance travelled along each axis in +- cm. So for example, if I move the imu 10cm forward and then 10cm back along the same axis I should see: +10cm x axis-10cm y axisThe same will apply to the rotation that occurs along each axis. This too will be printed out to the serial monitor.The final deliverable will be an Arduino sketch that performs the requirements set out above.

    We have a device that currently runs Arduino code (2500 lines) but is not a standard Arduino board. It is a commercial product that is based on an ATMega 1284P, 8 relays, Roving Networks Wifi, Digi Xbee, RS485, FT800 GPU, LCD and RTC. The code is getting complicated and needs to be optimized for performance, future expansion and reliability. We are looking for someone with serious guru C skills (as well as Arduino familiarity) to analyze the existing code, make suggestions on it"s improvement and, if agreed, follow through on those changes. If this small project is completed satisfactorily then further, larger projects related to the same hardware are very likely.Location is not a problem but we will provide you with example hardware. Real deep down AVR and embedded coding skills are required. This device communicates with a web-app so experience with Lua and Javascript that run at that end would be great but not required.Much more work is available to the engineer who proves him/her self.

    I have a prototype device that moves a stepper motor and is being controlled by an Atmel 8-bit mcu. The device was programmed in the arduino IDE and a simple GUI was created with Processing 2.03 and a GUI builder. It is basically finished but the original programmer left the country and disappeared without finishing some small software bugs (some calculation deliver crazy results if a negative number is used, motors perform a move accurately but reset their stated position to a random incorrect value when they arrive at their destination). I have the source code for all of it but I"m not a programmer. I would like someone in the Southern California area who can take a look and fix the bugs this coming week. I would consider someone far away but I believe you will need access to the hardware to test the code and I don"t want to ship it to another state or out of the country.

    Need a zigbee and arduino expert to help design hardware firmware to sit on an Arduino Yun compatible zigbee hub.We want to use this device as central zigbee hub:http://www.dragino.com/products/mother-board/item/71-ms14-p.htmlThis central hub will need to discover and communicate with local zigbee devices (1-30 devices) at local industrial locations.The hub will pass all the zigbee data to a Windows Based Cloud Server that will convert the zigbee information to OPC or Modbus. The Zigbee to OPC or Modbus conversion needs to be worked out (off the shelf, or custom conversion?). We will then have a full complement of off the shelf software available to provide the monitoring and control like the following:http://www.opcsystems.com/or instead of OPC, this one is based on Modbushttp://iconics.com/Home.aspxLooking for milestone based compensation. Please state your experience with Arduino, Zigbee, OPC and or Modbus.Basic functionality of the Arduino firmware will be to act as intermediary between cloud and local zigbee devices. Add on projects will be to add intelligence to the local hub so that is can do some rudimentary control at the local level without the need to communicate to the cloud.
