We would like to create a long term relationship with a Embedded Engineer / Developer Mandatory Basic Skills: - Arduino Development or Arduino like MicroControllers & MicroProcessors - ESP8266 AT Commands - TCP/TLS/SSL and WiFi - MQTT - I2C - JSON Nice to Have: - ESP8266 SDK Knowledge - Encryption / Cryptographic - PCB & Circuit Design - HyperCat and/or AllJoyn We have several projects to be developed in the course of the next 2 years, However for now this is a project on demand position that could lead to part/full time position. Thank you

Using a Rasberry Pi 2, monitor a analog input and using software compute commands needed to adjust a speed to maintain a set value. For example, if the set speed is 100, then we need to see if the actual value from the analog input is greater or less than this, apply a delay to adjust the response to match the real world response time. This value is then inserted into a RS485 ( Modbus) string and sent to a speed controller. This is a continuous process and is very slow response (5 seconds).

Hello, Android, Arduino, and SIMPLE electrical soldering projects available, more money if one guy can do it all! read below! I have existing Arduino code that I need to be modified. Currently, the Arduino code take an input from a reader and stores that unique signature to an attached SD card. I need the Arduino to also send the unique code to a Bluetooth enabled phone and to also send that captured signature to an antenna. The Bluetooth modules and Writer modules already exist for the Arduino and simply need to be added in a way that they all work together seamlessly. On the Android side of things: I need a very simple Android app that can sync to the Arduino's bluetooth module. When the Arduino sends a unique string of characters to the Bluetooth Android mobile app, the mobile app needs to store the unique string and add a time stamp. Secondly, once a unique string is captured by the mobile app, the mobile app will emit a text message/ringtone notification sound. Lastly,...

I am looking for someone who can code Arduino well. I want to make some LED lights react to certain tones. Here's the metacode: Power on (Starts up, slowly fades lights up to white) Listen for tone{ if Tone1 then change lights to blue if Tone2 then change lights to green if Tone3 then change lights to yellow if Tone4 then change lights to orange if Tone5 then change lights to red if Tone6 then change lights to Violet } if no tone detected for 2 mins, fade lights back to white If this sounds like something you can do, let me know.

Hello, Here is a updated description, we are looking at building a little toy that plays music and uses a motor and has lights. We would like the music, lights and motor to be controlled via bluetooth through a free app. We would like to be able to turn the toy on and off via a app. We have some modules but not sure if they will work. We have the Redbear Mico controller (http://redbearlab.com/blendmicro/ ) and the sparkfun mp3 shield (https://learn.sparkfun.com/tutorials/mp3-player-shield-hookup). Redbear has a free app that we would like to use for testing until we can make one. We will need to have three buttons for the Mp3 player on the toy to turn the volume up and down, and play/pause. We need a on- off button for the toy as well. We are not committed to using the modules that we have, if you know of a better way, we are open to improvements.

This is a well put together guide on building a syringe pump, using standard parts: syringes, arduino, stepper motors etc. http://www.instructables.com/id/3D-Printed-Syringe-Pump-Rack/#step1 The design for it is in google sketchup and parts list on that page. It has 0.5ul resolution on a 5ml syringe. I need the design modified to support 150ml of fluid to be processed and resolution of .001 to .04ml. I think this could be done with a much finer pitch threaded rod and or servo with more steps, but I don't know much about what stepper motors. Ideally only one motor as I this is to be used with a special filter. One possible design would be to have a giant syringe for the processed water driven by say a .5 to 1ml step, and a tiny one to run the processing at the super low flow. Looking for someone to take the existing design, modify and ideally build it or at least come up with a complete parts list that I can easily have someone purchase.

I need someone to tell me how to hook 2 stepper motors up to a dual stepper motor shield. I need someone to do this quickly. Here are the motors I have: http://maintextech.en.alibaba.com/product/60025636385-222759619/24BYJ_high_toque_stepper_motor_with_step_angle_for_IP_Camera.html And here is the shield: http://www.robotshop.com/en/dual-stepper-motor-driver-shield-arduino.html I need to know which wires go where. Then I will run the sample code to test it.
