My approach is to break down the system code into smaller more manageable task: 1) Arduino polls switch 1 continuously. If there is a state change, save the state into RAM 2) Arduino polls switch 2 continuously. If there is a state change, save the state into RAM 3) Arduino polls switch 3 continuously. If there is a state change, save the state into RAM 4) check if any button switch was pressed, if yes, send SMS to mobile phone 5) Arduino polls for any incoming sms, if any is received, parse the data and set corresponding flags 6) depending on flags, turn LED on or off. A form of multi tasking will have to be employed to ensure all inputs (button switches and sms received) are not missed. For SMS reception, auto receive will be enabled by AT commands so that messages are routed immediately to the Arduino instead of to the SIM card (AT+CNMI) For sms transmission, it would be straight forward. (AT+CMGS)

Hi there! It is not very clear as to what you want the freelancer to do. Is it just the software development, or do you want a PCB designed, or do you want a working prototype? This information would be helpful for us in deciding a bid. Thanks and regards, Pranav

Hello! I have experience programming in C / C + + for almost 20 years. Devices based on Arduino, I'm doing more than 3 years. I have experience making "smart house" on the Arduino. More, I have experience in: - building hydroponics installations on Arduino - the control system with LED lights - equipment for the reality-show "Treasure Room" (complete within 3 days) - Control system for printing equipment (now in progress). I am ready to write a program for Arduino and provide a complete description of the device. But I have an obligation to other projects. I am ready to take your project if you give enough time - at least 3 weeks.
