Arduino Calculator Circuit Diagram. The complete circuit diagram of this arduino calculator project is given above. On this project me and my team are building a simple calculator with 4 basic functions using keypad as input and lcd as output and can only compute up to 2 digits.
In this project we are going to make an arduino uno calculator which will take the values from user by using the 4x4 keypad and then will perform the calculations to get the result. First the connection of lcd display to arduino uno. The design of the circuit is explained here.

The arduino itself can be powered from your laptop or through the dc jack using a 12v adapter or 9v battery. Lcd is used in 4 bit mode and hence only 4 data connections are needed.
