1. Introduction Welcome to this lesson on push buttons! In this lesson, we will be learning about the basics of push buttons. we will learn how to program and interface a push button with an Arduino, using digital inputs. By the end of this lesson, you will have a solid understanding of how to use and implement push buttons in your projects. So, let's get started! 2. Definition A push button is a simple mechanical switch that is typically used to initiate an action or event when pressed. It is often used as a user interface element in electronic devices, such as phones, computers, and appliances, to control various functions. Push buttons come in different shapes, sizes, and types, such as momentary, latching, and tactile buttons, and are activated by physical force. Push Button They are typically made of plastic or metal and can be found in a wide range of applications from elevators, home appliances, or industrial equipment. 3. Pull-up  resistor A pull-up resistor is an...

1. What is a LED? An LED (light-emitting diode) is a semiconductor device that emits light when an electric current is passed through it. LEDs have two main components: the anode and the cathode. The anode is the positive terminal of the LED and is typically the longer of the two leads. The cathode is the negative terminal of the LED and is typically the shorter of the two leads. LED When an electric current flows through the LED in the correct direction (from the anode to the cathode),  it causes the semiconductor material inside the LED to emit light. LED ON 2. Connecting an LED to the Arduino UNO Connecting an LED to the Arduino UNO is a simple process that involves connecting the positive leg of the LED (the anode) to a digital output pin on the Arduino board and the negative leg (the cathode) to a ground pin. Connecting an LED to the Arduino To protect the LED from burning out, we need to use a resistor. The resistor can be placed: between the digital output pin an...

  1. Definition The Arduino Integrated Development Environment (IDE) is a software tool that provides a graphical user interface for developing and uploading programs to an Arduino board. The main features of the Arduino IDE include: Code Editor Toolbar Menu Bar Console Board and Serial Port Selection Upload Button Include Library The Arduino  IDE 2. Code Editor The code editor is the main component of the Arduino IDE. It allows you to write, edit, and debug your program using a syntax-highlighting feature, which makes it easier to read and write code. It also has features such as line numbering, code folding, and auto-indentation, which make it easier to navigate and organize your code. The Arduino IDE : Code Editor 3. Toolbar The toolbar provides quick access to common functions such as compiling and uploading code, opening new sketches and saving sketches. It also has a button to open the serial monitor. The Arduino IDE : Toolbar 4. Menu Bar The menu bar allows you to acc...

  1. Definition Arduino boards are programmable electronic boards, part of the microcontroller family, with a certain number of inputs/outputs. An Arduino board is essentially made up of : A microcontroller manufactured by Atmel. An USB port. Input/Output connectors. The most famous models of Arduino are: 2. Arduino Uno In our future projects, we will use the UNO model. It is composed of : An ATmega328P microcontroller. 14 digital input/output pins, 6 of which can generate PWM. 6 analog pins. Power Pins. Crystal oscillator clocked at 16 Mhz. Barre Jack (power inpout). USB. Reset switch. 2.1. Digital Pins Each of the pins 0 to 13 can be configured as an input or as an output. The signals conveyed by these pins are logic signals, so they can only take two states: HIGH (5 Volts) or LOW (0 Volt). Warning: the connectors cannot supply an output current greater than 40 mA. 2.2. Analog pins Contrary to the digital pin which can only take two states HIGH and LOW, th...
