Looking for someone to finish a code, we are a group of designers developing an interactive kiosk that takes the pulse and then generates a patten based on the heartbeat recorded. The touch sensor code is already written, we just need someone to write the code that draws stripes based off of when the heart beats. Payment is negotiable. Further Description: The code needs to take the pulse sensor data measured between 5 seconds and 30 seconds, and draw horizontal lines that correspond to the heartbeats. The spacing needs to be dependent on the amount of lines, the lines need to fill a 13 x 13'' square. Every 3rd line drawn should be 60% larger than the previous two, and the number of lines drawn should be equal to the number of beats from the data collected from the touch sensor.

Hi, Im looking for someone to help me finish a simpe project where 60 singel controlled leds are going to be controlled based on the time from a RTC modul. And possibly have a sound sensor aswell, wich i havent decided yet. It shouldnt take more than 2-3 hours as some of the code has been written. It just needs finishing and testing. the details of the code and testing will be communicated upon agreement The RTC modul is a DS 3232 and the led strip is a WS2812

Design a PCB based on a prototype made with Arduino Mega. I have all boards and components schematics used in the construction of the prototype. Also within the design work, is to search components that have the same functionality but to lower the cost of the final product. ------------------------------------------------------------------------------------------ Diseñar una placa PCB en base a un prototipo hecho con un Arduino Mega.

I have a small project that entails programming a Atmel ATTiny841 microcontroller. The controller will receive a serial input command and will need to send PWM signals to three output pins based on the input command. I have already proto-typed this using the Arduino Uno. I have the code written using the Arduino commands. I need someone to rewrite this code for the ATTiny841 in Atmel Studio 6.2. I can share design schematics, block diagram, pseudo code as well as my Arduino Uno code. I need someone who is proficient in Atmel uC programming who can do this profesionally with the correct libraries etc..

Hi, Found you in the Arduino sub section, I am in Vancouver Canada Job is to make a 12 volt DC winch motor controller that will wind in or wind out the line depending on changes in sea water height from tidal changes. Sea height is measure by taking average of 10 wave heights every 10 minutes and comparing this to a base value and if exceeds or not a set amount, then the motor is turned on. Duration of time motor is is in determined by length of cable moved based on digital revolution counter which counts revolutions of winch drum, in 360 steps per rev. When set length is reached then motor stops and water height measurements are made to confirm. It is expected to move winched device approximately .5 m per move, which, on average in Georgia Straight, will be about once every hour or so. The wave measuring device measures water pressure above the device and the out-puted digital data occurs at 6 Hz.

Using an UNO and GPRS shield (from Tinysine), wake up from sleep mode every hour to measure temperature of DHT11 sensor (captured over 10-15 seconds) and send data by HTTP request via the GPRS shield. If connection isn't available, retry 5 minutes later. If still not available, store data until next attempt (1 hour later).

Hi! I need some kind of reverse engineering regarding Arduino DSLR trigger from PC application. So, I have demo version of one software witch is used to trigger DSLR camera based on GPS location. Please see schematics here:   [obscured]  /s/ma5zezt904qqiqw/Untitled-1.jpg?dl=0. So I need to replicate that trigger box (in wich is some kind of Arduino board i guess. I need someone to inspect software (.Net Framework) which I would sent you and try to rediscover what arduino components i need to replicate that box. On one side od trigger box is USB cable, and on the other there are two cables. One is simple on/off switch to trigger camera, and other one is connected to flash output on cammera and it sends the pulse back to software to get feedback that camera has triggered.

I need a program for an Arduino board so that it can generate 4 types of PWM. 1. Sinusoidal pulse width modulation - SPWM 2. Selected harmonic elimination - SHE PWM 3. Space Vector PWM - SVPWM 4. Hysteresis band current control PWM The user must be able to select the type of PWM that he wants and the frequency (1-200 Hz). The frequency will not be changed with a potensiometer because of the noise but from from the serial screen. The system is intented to work with a SINGLE-phase inverter. The Arduino board that will be selected will be anyone with an ATMega micropcessor. The final deliverable should be the arduino code files with extensive comment documentation.

Looking for an English-speaking freelance Windows mobile app developer to work on an XAP (written in C#) that runs on Windows Phone 8, uses a Lumia phone camera, does streaming through an Azure connection, does remote control interfacing (via LTE and/or WiFi), and uses Bluetooth to interface with Arduino. You have to be able to deal with all these variables + know the basics of JSON. Our app is built to take photos from a Lumia phone and push them into the Azure cloud. The Lumia is mounted into an automated telescope, controlled by an Arduino. Work will need to be completed by May 3 2015. We need to implement: * Video streaming into Azure cloud * Time lapse photo taking and push to Azure * UI for Remote control of the telescope from across the world. The phone connects via Bluetooth to an Arduino which controls the telescope mount. * A UI for connection config between scope and phone A more detailed spec will be issued on candidate application.

Without seeing the design I have in mind for this project it will be difficult to explain to you exactly what we want to produce. Essentially we're in need of a square panel (apx. 30"x30") made out of a .5 inch white cast acrylic that is translucent enough to trigger LED sensors through it. These sensors will need to be able to control volume, music controls (play, pause, next, etc.), an LED light strip, and a relay switch that powers two 110v 10watt lights. The panels audio components will need to include a bluetooth receiver for controlling and inputting mobile devices. It also needs an option of a 3.5mm stereo input that will bypass the bluetooth's audio for direct connection. This will all need to be output to a stereo jack (3.5mm or RCA). For lighting, the panel will need to include three functions for controlling a RGBW LED light strip. These need to include, set color, auto dimming, & sound activated responses. Also we need a relay sensor/switch to power on &am...

Hi folks, We have launched an open beta testing of a DIY platform for open source hardware projects. The platform is intended to help new people to start using open source hardware and help experienced developers to work together on the same project remotely by following each other's instructions and contributing to project by submitting patches. During beta testing we want to collect feedback about usability and platform functionality, as well as bug reports and feature requests. We also need to generate some content before the public release. This job posting is first of all about content generation. So we need someone to apply for a beta account and create a project using either Arduino or RaspberryPi circuits. You will need to have your OWN arduino/raspberry pi circuit and rest of the parts required for the project. Project can be fairly easy, but should be complete (so that other people can assemble same device following your instructions) and contain at least 10 steps with sev...

Looking for freelancer who can prototype a small working version of marked moving object pickup Robot Arm [This could be considered as Toy Robot, which we can buy on-line for around $ 40-60]. In real world the Arm should be capable to pick up 5-10 kg weight object by its handle [lift up to 0 - 24 inch high, which is configurable], handles are marked with X sign or say specific color. Handles are always positioned to be picked up by Robot Arm, but they are moving linearly very slowly, just need to identify them by X mark or color. It should reject or ignore other handle objects and carry that object to up to 10-12 ft [configurable] distance and drop there gently. The Robot Arms will be hanging on the circular Rail Track on the roof, which is either stationary or moving and based on that the Arm should move on track. The Arm should be programmed to repeat the task automatically. Once switched on, its function is continuously look for moving marked objects, pick them at one end and drop a...
