Arduino programming and hardware help

Using Aduino Mega, adafruit datalogger shield, and suitable cost effective LCD display of your choosing You must have Arduino experience! I have none! Write a sketch for Digital Inputs: 11 switches; Named: Up, Down, Left, Right, a+b, c+d, e+f, Run, Learn, Replay, Clear all switches must be de-bounced. Digital Outputs Run, a+b, Up closed = digital pin1 PWM 75% Run, a+b, Down closed = digital pin2 PWM 75% Run, a+b, Left closed = digital pin3 PWM 75% Run, a+b, Right closed = digital pin4PWM 75% Run, c+d, Up closed = digital pin5 PWM 75% Run, c+d, Down closed = digital pin6 PWM 75% Run, c+d, Left closed = digital pin7 PWM 75% Run, c+d, Right closed = digital pin8PWM 75% Run, e+f, Up closed = digital pin9 PWM 75% Run, e+f, Down closed = digital pin10 PWM 75% Run, e+f, Left closed = digital pin11 PWM 75% Run, e+f, Right closed = digital pin12 PWM 75% Learn, Run, a+b, Up closed = digital pin13 PWM 75% and write how long (time) Run, a+b, Up were energized to SD card Learn, Run, a+b, Down closed = digital pin14 PWM 75% and write etc... Replay, Run closed = read data from SD card to enegize output pins from Logged data on SD card Clear, Replay closed = delete logged data on SD card if a+b and c+d or e+f closed at same time = no outputs LCD to display I/Os and fault if a+b and c+d or e+f closed at same time.
