In this tutorial, I’ll show you how to setup a keypad on theArduino. First I’ll explain how the Arduino detects key presses, then I’ll show you how to find the pinout of any keypad. As a simple example, I’ll show you how to print out the key presses on the serial monitor a...
In this basic tutorial we will learn how to setup a keypad on an Arduino. Keypads can be used to control access to things, such as unlocking a door or a safe. Keypads can be added to a myriad of Arduino projects, for learning, or for real world projects. In addition to controlling...

To reset the program, we have defined a key that when it is pressed it will clear the LCD and the setup function will be called to restart the Arduino code. Here in the code we have assigned the key “A” of the keypad to perform the BMI calculation and the key “C” of the keyp...
We can even connect a LCD display and keyboard to Arduino and make a scientific calculator, but it is subject of another article. If you are familiar with “Turbo C++” one of our first programs will be addition of two numbers, all the arithmetical calculations are carried within the CPU ...
As you can see, there are 6 servo motors attached with the Arduino outputs and each of this is controlled through the remote controlled signals captured by the attached sensor NRF24L01. The signals is processed by this sensor and fed to the Arduino which delivers the processing to the relevant...
When the human interface is required to give an input to an Arduino program manually different devices like keypad or push buttons can be used. Moreover, we can configure the functionality of such devices by programming the microcontroller. For instance, when we have to turn off some device, ...
Hi there, recently I bought an Orange Pi Zero3 with 1GB RAM. I want to connect a 20*4 character LCD display(https://www.tinytronics.nl/en/displays/lcd/lcd-display-20*4-characters-with-white-text-and-blue-backlight-with-i2c-backpack) to it. I have previou
