Hello dear I have worked on BLE projects and also have experience in developing android apps,,,I can make your project,,,If you wish we can discuss in chat,, You can take alook into my profile for my previous similar projects..

I have 4 years experience in embedded systems . I have completed many projects like it and also controlling electronic thing using iPhone . I can do your job within a time limit. but provide me a iPhone app for it .

i am an electronic engineer with more than 6 years of experience. i have experience with iphone app development and interfacing external hardware with iphone.. i can make the buzzer board small if you prefer that. please contact me to discuss details.

Hi there! My name is Keith and I am a professional engineer living in Tennessee, USA. I graduated from Vanderbilt University with a mechanical engineering degree in 2012. Previously having worked in the aerospace industry, I am now a full time contractor and work on a wide variety of product designs for personal customers, Kickstarter businesses, and entrepreneurs. Feel free to take a look at my profile and portfolio, I think you will be pleased with my qualifications! I am glad to talk about the details if you'd like to message me here on Freelancer. I look forward to the possibility of working on your project and thank you for your consideration. - Keith A.

Designed over 300 circuits on several EDA tools like Eagle, TINA, Orcad, as per given specification i will die try to design and design this out

Dear Sir. I am an Electrical and Electronic Engineer and highly experienced on Wireless based Embedded Electronics Development with various Sensor integration and Firmware Programming. Please have a look on my Freelancer Portfolios where I have uploaded my several past projects. Sir, I have sound knowledge on Schematic, PCB Designing using "Altium Designer" as well as Firmware Programming. Also it is to inform you, I have known China/HK based Manufacture and can able to assist on professional Prototype Production with SMT Assembly and Component Sourcing. I have reviewed your job post. To enable the communicate with SmartPhone now a days Bluetooth 4.0 (Low Energy) is the best choice in terms of Power Efficiency and Low Production cost. Sir, I alrady did similar project considering control device through SmartPhone App over Bluetooth LE. I can make a compact design by interfacing with a Buzzer. I'll be glad if you please arrange a meeting for further discussion. Thank you. Looking forward your reply. Regards. Nazmus Sakib,

tengo la vision y la proyección del proyecto ha realizar. Para poder realizar este proyecto se necesita tener un microcontrolador (preferiblemente arduino), luego se diseña la apliacacion especificamente para iphone para controlar ya sea la shield ethernet o controlar el modulo Wifi , para realizar dos pcb individuales cada uno con un buzzer que suene con una frecuencia distinta se lleva las conexines de cada pcb al microcontrolador con la ethernet shield y de se lleva a un un routers Wifi mediante un cable ethernet o otra opcion conectar el modulo de arduino uno con módulo WIFI ESP8266 para controlar los dos pcb con los distintos buzzers sonandolos a distinta frecuencia.
