    I need someone to develop an electronic circuit for a floating swimming pool alarm. The main components of the circuit will be: a solar panel; a rechargeable battery; a micro-controller; an accelerometer; and the buzzer. I need someone to simulate it in a specialized software; to develop all the technical documentation, the list of the necessary components (with costs) and a prototype of the circuit, so I can test it before manufacture. I already have the plastic floating case in ...

    1. Create a simple sketch for an Arduino Uno that reads this rotary encoder https://www.sparkfun.com/products/10982 (here is the breakout board I am using too https://www.sparkfun.com/products/11722 ) on an interrupt basis and increase a numeric variable by 1 per detent up if turned one way and down if turned the other way. Print that variable out to my serial monitor on my pc. 2. Create a simple wiring diagram for me to ...

    Need to develop a simple circuit which can store a 10 Digit Number like "98-11-28-79-81" in a permanent memory (ROM or FLASH) On pressing of a button, the 10 Digit number read from the memory and is converted to Binary and Frequency Shift Keying (FSK) is applied to generate an audio message. The base frequency being used for the FSK - is around 22 KHZ. This audio is played out aloud through a Ultrasonic Transmitter. The audio will have a preamble ...
