All by itself, a calculator based on an Arduino isn’t necessarily very novel. However, [Danko Bertović] of Volos Projects has a nice board that, of course, looks like a calculator. There are … ...

We’ve all got calculators on our phones, in our web browsers, and even in the home “assistant” that’s listening in on your conversations all day on the off chance you blurt … ...

CONCLUSION In conclusion, the development of a simple calculator using Arduino and a keypad underscores the versatility and accessibility of microcontroller-based systems in practical applications.

In the era of digital technology, the integration of computational tools into education and professional practices has become essential. This project serves as a practical tool for students and ...

Featuring an Arduino Nano microcontroller board and the keyboard from a small numeric keypad the LCD display the calculator is powered by a set of AA batteries through a DC-to-DC converter.

To make that actually work, Robofun paired an Arduino board with some capacitive controllers for the base, and connected that to a Raspberry Pi that linked the keyboard to the TV.

The Gesture Keyboard is a device that translates gestures into letters. It’s made by an Arduino Pro Micro, an HC-06 module for Bluetooth communication, and an MPU-6050 accelerometer.

Robofun Create has built a fully functional keyboard using Staropramen beer cans, demonstrating once more that the potential of systems like the Arduino and Raspberry Pi is only limited by the ...
