    Need co2 levels displayed on lcd in real time in percent. For example 40,000 ppm will be displayed as 4.00%. It will also show the valve status (open or closed) Buttons on LCD will control the co2 threshold. Once the co2 reaches the threshold the valve goes off. Below the threshold the valve is open. Threshold is set in percent as well. So if set at 4% the valve will stay open until it reaches 4% and then close.Let me know if you have further clarifications.

    Hello campaigner,Our project is based on a Raspberry Pi.The device needs to allow a user to interact with a Screen, Flash Drive and Raspberry Pi.In Simplicity:Phase 1:A user needs to place a "media" file (Video or Image) in a predefined directory on a Flash drive. When the Flash drive is inserted in to the Pi, the media should be automatically loaded and rendered to the screen. Phase 2: ONLY ONCE PHASE 1 is COMPLETE - includes it"s own budgetA User should be given a GUI to this process and be able to schedule the media file to play / stop between a timestamped period. In the above, lea-way should be made to trigger a switch mechanism (which will be connected to the PI"s GPIO pins) that controlls a light.

    Hello,I am looking for a simple application that, using the OpenNI toolkit (or using the Microsoft provided ones, if it is simplier), have a simple method to record a user"s movements as a "base", then allows a second user to be "recorded" while comparing the second users movements against the first one. More specifically, we are looking for what is described in the PDF located here - as the Data Acquisition Software GUI (Figure 2). As the screenshot there shows, there is a base model (which was prerecorded), and a new model that is compared against the baseline to determine the relative position of joints between the two models. The screenshot shows a rather intensive comparison and for this stage in the project we are just looking for a more crude comparison based on relative comparison (and highlights the points in a given movement where the two recordings are significantly out of sync). It is important that the speed is not important and that the comparison just compares movements, not timing. Any open source toolkit is welcome as long as it is mentioned and clearly indicated. All code must pass StyleCop ( review, be well documented, and otherwise follow the guidelines located here - Code should be C# unless otherwise agreed.

    I need to monitor if a screen is on or off by collecting the light emitting out of the back of the LCD panel. I need to use this information to determine if there is enough light to indicate if the screen is on or just telling me that its off if the light reading is below a specific value "which i can determine".I want to then integrate this to a central cloud service where i can add multiple screen monitors and keep track of their state.I am currently using an Arduino Uno with Wiznet 5100 ethernet shield. I would also like to add on relay functionality to the Exosite cloud.In a nutshell i need to see all my LCD screens on/off status in one browser page for monitoring purposes and have switches next to each screen linked to relays to turn screens on/off and the respective dashboard light will indicate the exact status.

    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 - is the breakout board I am using and the connections I have set up: 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.

    Hello,This project requires adept skills in Arduino or ARM microprocessors. What we are creating is a robot to demonstrate how to play robot soccer for a tournament. The robot should be able to understand which of the two goals to score into, where its position is on the playing field and its facing position, where the ball is and, preferably, have the ability to carry the ball and avoid collisions with other robots on the field. The designs of the robot has already been created and uses a base with four omniwheels to control the robot. The project will require a code that will either work for both robots universally, or a specific code for each robot. It would be extremely preferable if you could create a custom PCB with all the required components on board ready for work. I will need to have very close contact with the developer/s as there is much more further discussions required. (Please provide evidence of previous projects of similar nature)Thank you!
