This project will control of the huge amount of white single leds , i have already the schematics for the controller board and led drivers.

Controller board includes 1 Atmega328p, 1 HC-05 bluetooth module and controls via SPI interface. Every led driver board will have cascaded 4 TLC5940 led driver chip. So there will be 64 channels led driver board and each board will be connected via SPI interface so i can connect as many leds i need via extending the led boards. Also these leds will be controlled from android device via bluetooth.

Atmega328p has to be programmed to connect the TLC5940 via SPI interface (i already have that schematic and library for TLC5940)

HC-05 module has to be connected to USART of atmega328p

4 TLC5940 have to be connected eachother and controlled via SPI (i already have that schematic)

Android Application has to meet the requirements of

1- turn on all leds

2-turn of all leds

3-turn on specific single led

4-make shows turning leds on and off in various states (at least 3 shows button needed)

5- the most important there must be a button and if i press that button it must keep that single turn on led in the memory so i can recall the leds in the memory later(for ex. i turned on the 45th led and pressed the button keep in memory then 56th led then 89th led etc.. after i press the button that must turn the leds in the memory)

6-erase the specific led from memory (previously i keep the 45th led in the memory and now i choose the 45th led and press erase this from memory)

7- single button to erase the whole memory

i need this within 7 days maks.
