There are numbers and signs on the remote control.
How I built it
Get the value from IR sensor, then convert them into numbers and operators. Finally evaluate.it.
Accomplishments that I'm proud of
I can get the answer by the program.
What I learned
It's my first time to use hardware, so I learnt much related knowledge. For example, how to use the control board.
Add more operators such as square root. Deal with the priority of operators.
