Hey! This will be a small project with quite basic skills required. This will be very much like an alarm wake-up circuit with bluetooth and app control. But instead of the alarm it will be outputting an electrical signal at the defined time. There will be an app interface where a user can define an time for when the circuit will output a electrical signal, when the user has chosen this time, it will be saved on the circuit. The user will also be able thru the app, to remove the chosen time and set for how long the circuit will output a electrical signal. When the user selects to remove the signal it will be removed of the circuit. After the user has defined the time the signal has been outputted it will be sent to the circuit and saved there. Then when the time is the same as the user defined the circuit will output an electrical signal. The length of this will be as the user defined in the app. When the signal has been outputted successful at the give time, it will be deleted from the circuit and the user can define a new time. Things the app will do: - User can define a time the circuit will output a electrical signal - User can delete the defined time. - User can set the how long the electrical signal will be outputted. - When the electrical signal turns on the user will have the ability to stop the electrical signal before the set time has past. - The app will also monitor the battery level of the circuit. Things the circuit will do: - Receive and send bluetooth signal to the app. - Output an electrical signal that the user has defined at the give time. Required skills: - PCB/Schematic/circuit creation. - App (iPhone/Android) creation. - Possibly microprocessor development. Budget ($250)

Greetings, I know you mentioned a budget of $250, but what you need involves circuit design, pcb design, firmware for the pcb, testing and app development. That's a lot of work. I don't think you can get a quality job done for this budget. I have good expertise in these areas and I can do the Android App as well - Please see a similar system that I had done recently on my portfolio (High Impedance AFE). I don't have expertise on iPhone App so won't be able to do that. Let me know if you are open for this budget - I can get you the final working system. T & R Alok Pugalia

Thanks for inviting me to bid on your job. The price and timescales are just place holders at the moment. I am afraid I could only help with the PCB, not the firmware, app or enclosure. If this is still useful for you please come back to me describing the electrical signal you require Best Regards Dave lelievre

@rajudp

hello, i am doing embedded designs and programming i can do this project with Android phone need little more details if my bid selected the plan will be like this from the application there wil be an option to set a ON/*OFF time to the circuit from the application there will be an option to reset the time stored in circuit the application will show the battery level of the circuit the circuit work on PIC microcontroller with a RTC circuit the circuit will ON/*OFF the signal depending upon the set time (if needed clear the set time from circuit after the signal ON/OFF) *OFF time setting is for time more than a minute to 24 hours if on time is short then instead of OFF it will be the delay to Keep on i can provide circuit/PCB layout , APK file for android , Hex File for micro controller(if needed source file with little extra cost) i can test the working in real hardware from my side if interested please contact
