This simple Arduino project aims to display constant values on the screen at specific intervals through the serial monitor without requiring user input. Every second, constant integer values are ...

Getting a blank page on the Arduino Serial Monitor when you want to see the data from your sketch is frustrating, but we have some fixes.

For this, just wire up the hardware (arduino+keypad) as described earlier. Although the code is an entry-level one, it includes a secret key option that will need to be entered on the keypad. The ...

AtTiny85-Arduino-Serial-Monitor Serial interface for ATTiny that allows you to print different data types to an arduino's serial monitor. Doesn't require any extra serial cables/devices. This uses ...

In this project, we'll go over how to interface a 4x4 membrane keypad with an Arduino microcontroller. By the end of this tutorial, you'll be able to read the state of the keypad and determine which ...

An Arduino Uno provides the processing power and drives the serial monitor. A joystick and a Hitachi H48C accelerometer are mounted on a breadboard and wired to the Uno.

If you want to add a keypad to your Arduino project, the options are pretty limited. There’s that red and blue 4×4 membrane we’ve all seen in password-protected door lock projects,… ...

In this project we have built an Arduino Keypad Door Lock which can be mounted to any of your existing doors to secure them with a digital password.
