How I built it

Get the value from IR sensor, then convert them into numbers and operators. Finally

Accomplishments that I'm proud of

It's my first time to use hardware, so I learnt much related knowledge. For example, how to use the control board.

What's next

Add more operators such as square root. Deal with the priority of operators.
