Question

6.3.7. Analog write and digital write methods Do this Similar to the ar and dr methods, write the methods aw and dw. Each of these methods has a pin number parameter and a value parameter. Write the value to the corresponding analog or digital pin instance. Just like ar and dr, write the value to the pin only if the pin number is in the correct 17 range. These functions do not need to retum anything. One other thing: in the dw method, if the pin number is 13 then print a message to the screen. If the d13 pin is set to 1, then display "LED is on", otherwise display "LED is off This simulates the on-board LED found on all the Arduino boards. Neither of these functions should return anything. Test it If you write a value to any pin, then the next value read from that pin should be the same value that you just wrote to it. If it is an analog pin then the value will be multiplied by 4 6.3.8. Digital mode Do this Add a dm method. This method is quite similar to the dw method. It has three parameters: self, pin number, and mode value. It works like this if the pin number is in the correct range find the correct pin in the list of digital pins associated with this instance set the mode of that pin to whatever the parameter variable is You will use this method to set the mode of pin 13 in your bilink function that you'll write later.
