Using tinkercad, create a circuit that can convert hexadecimal to decimal

1. Modify the code from the Keypad and LCD circuit so that it reads a 1-digit hexadecimal number from the keypad and displays its equivalent in decimal on the LCD and then repeats this process. For example if you enter E (hexadecimal) the circuit should display 14 (decimal).

2. Make a copy of the previous circuit and modify it so that it now reads a 2-digit hexadecimal number from the keypad, converts it to decimal, displays this on the LCD and then repeats this process. For example if you enter 1F (hexadecimal) the circuit should display 31 (decimal).

3. Make a copy of this circuit. This contains the keypad as before, but the LCD display has been replaced by a 3x2 array of LEDs. The code is incomplete and does not drive the LEDs. To control the LEDs you can use the pinMode and digitalWrite Arduino functions2. You may need to refer to the Arduino documentation for more information about these functions. Complete the code for this circuit so that it reads a 2-digit hexadecimal number from the keypad and displays the corresponding Braille ASCII code on the LEDs. If a hexadecimal number less than 0x20 or greater than 0x5F is entered then the display should not change.
