A piezo buzzer is a small device that converts electrical signals into sound waves. Unlike traditional speakers, piezo buzzers operate on the piezoelectric effect. When a voltage is applied, the buzzer's piezoelectric crystal deforms, producing sound waves. This simplicity makes piezo buzzers cost-effective, lightweight, and ideal for applications where the space is limited.
Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language and the Arduino Software (IDE).
In the world of DIY electronics, Arduino stands as a go-to tool for creators and hobbyists. Today, we're exploring the integration of a 4x4 membrane keypad module with an Arduino, a combination that introduces an interactive layer to your electronic projects.
Arduino microcontrollers are the heart of countless DIY projects, from robots to automated systems. To bring these projects to life, you often need to interface them with motors. In this guide, we'll walk you through the essential steps of connecting a motor to an Arduino using a separate power supply while ensuring control with precision using an NPN transistor. This approach allows you to harness the full potential of your motorized creations without overloading your Arduino.
Let's speak now about switch buttons, the wiring and how to implement the code for this circuit elements in Arduino. Switch buttons connect two points in a circuit when you press them and maintain the state without the need to keep the button pressed. That means that logic state of the circuit change every time you press the button.
The Simpsons, that legendary animated series we all know and love, has become a cultural phenomenon. With its hilarious take on family life in Springfield, it's an absolute classic. We decided to have a bit of fun and recreate the show's iconic theme song using a piezo buzzer.
Buzzer is used to generate sound, beep or even melody of a song. It can be found in alarm devices, computers, timers and confirmation of user input such as a mouse click or keystroke. A piezo buzzer is not like a regular speaker that you might think of. It uses a material that actually changes shape when you apply electricity to it which in turn creates noise. The faster you bend the material, the higher the pitch of the noise that is produced.
Touch sensor (also known as touch button) is widely used to control devices. It detects touch, force or pressure on its surface changing the logic state of the circuit. Actually, it works in very similar way as to buttons. Checkout the wiring and Arduino code implementation to track the current state and the state changes.
Ever wondered how your phone manages to stay charged without blowing up or how your TV remote controls those watching marathons? It's all thanks to a tiny but mighty electronic component - the resistor. Resistors are one of the most valuable parts of the tech world. These little wizards quietly control the flow of electric current in ways that make our gadgets tick. In this article, we're taking a deep dive into the world of resistors, from the magic of Ohm's law to cracking the colorful code that reveals their hidden values.
We often use the power supplies like batteries or direct AC/DC supply which are normally in higher ranges compared to the actual requirement for the circuit. In that cases we need this kind of voltage regulators which can regulate and vary the voltage levels for the circuit requirement.
The AMS1117 series of chips are linear voltage regulators with low voltage drop. The modules based on the AMS1117 chip provide constant 3.3V or 5V outputs from an unregulated DC input. It's very compact and can be included in your project schema or you can use it together with a breadboard for circuit testing.
A tilt sensor is a type of sensor that can detect the orientation or tilt of an object relative to the force of gravity. It works by measuring the change in angle of the object with respect to the vertical axis.
Tilt sensors can be found in various forms, such as simple mechanical switches, mercury switches, and electronic sensors. They are commonly used in applications that require the detection of tilting or changes in orientation, such as in construction equipment, automotive safety systems, robotics, and gaming controllers.
