Description:
Implement a basic Calculator using an Arduino, push buttons/keypad and LEDs
The calculator must perform at least the basic arithmetic operations ADD, MULTIPLY, SUBTRACT and DIVIDE
the result may be displayed on the serial monitor, although using an LCD component is preferable (LCD will be required for the next project). Bonus points (up to 30%) will be awarded for use of LCD, use of the additional functions FACTORIAL, ODD or EVEN, MODULUS and PRIME FACTORS.
The submission requirements are a report, source code (INO file) for the Arduino and link to the tinkercad design.
You will be required to show a short (~5 min) demo of the project working.
