Learn electronics, coding, and projects — step by step.
When I started learning the Arduino microcontroller, I searched for ways to use it immediately because I believe that the best way of learning something is by experiencing it firsthand. In this tutorial, we will learn the basics of Arduino GPIO — General Purpose Input/Output, or in simpler terms, Arduino pins. GPIO are physical pins […]
Building an Android application is one option to control your robot project or anything that comes to your mind. And with the use of the MIT App Inventor 2, you can easily create an Android application. In this tutorial, we will learn to create a simple Android application which can control the state of the […]
With this article, we will create a remote control (RC) car with the use of HC-06 bluetooth module to make it wireless and L298N motor driver to control speed and direction of rotations of the motors. CIRCUIT DIAGRAM BILL OF MATERIALS Arduino Uno as the main board HC-06 bluetooth module to receive commands via bluetooth […]
In this tutorial, we will learn on how to use the LCD Keypad Shield for Arduino. This shield is compatible for Arduino Uno and Arduino Mega. PINOUT From these pin assignments, we can conclude that the following pins are free and available for other purposes: Digital pins: 0, 1, 2, 3, 11, 12, and 13 […]
Interrupt is extremely useful when dealing with all kinds of processes that need attention at unexpected times or when expecting a certain event or signal at indefinite and unknown times. For example, you send a chat message to your crush. You are very excited but also nervous. So every second you are checking your messenger […]
