Make a simple calculator with Arduino MEGA. via instructables
Nowadays, doing calculations isn’t a problem at all. Powerful calculators can be bought for few Euro or easily installed on phones and computers. However, we decided to turn our Arduino into a calculator because we think it could be a really interesting experiment.
It’s actually a very simple calculator, in fact it can just do the four basic calculations accepting only integer positive numbers. Despite this fact, the sketch is quite complex – and you’ll figure it out on next steps -, but the circuit is pretty easy instead and requires few and common components.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
