Its a very simple arduino project.

Hello, I would like to write me the arduino code for a very simple project that I want to do. I need it as soon as possible 1-2 days maximum. I will have the followings materials: - arduino mega - arduino screen lcd (model: LCM1602) - 8 relay module - 4x3 arduino keyboard - 1 potentiometer - 1 rf remote control with 8 buttons (please advice me which to buy from ebay) - 1 rf receiver (please advice me which to buy from ebay) This project is to control 8 relays with timer. I want to use the potentiometer to control the timer, range must be from 0-300 seconds. I want to control the relays by using 2 ways: 1 way: by using the keyboard. When I press 1-8 numbers, I could select from 1-8 which relay I want to open by pressing the * and then timer to start counting. When counting finished the selected relay to close. If i press # the relay must stop. Each time only 1 relay can be working. 2 way: I want to use a rf control ( i found some remote control with 12 buttons) The remote control will work with the same way as keyboard. Choose from 1-8 the relay to control. Start button could be number 10, stop could be number 12 from remote control. The screen has 2 rows. The first row I want to show the timer. For example, 0/100 seconds when is close and when is working the time to run. 10/100 seconds. The second row I want to show which relay is selected and is working. For example, Relay 1 - close , then Relay 1 - open Before to give me any offer please read very carefully what I had wrote above. thank you
