Button-Controlled-LEDs-with-Arduino

Overview

This project demonstrates how to control three LEDs using three push buttons and an Arduino UNO in Tinkercad. Each button is connected with a pull-down resistor (10 kΩ) and controls one LED.

• Button 1 → LED 1
• Button 2 → LED 2
• Button 3 → LED 3 When a button is pressed, the corresponding LED lights up. When released, the LED turns off.

Components Used

• 1 × Arduino UNO
• 1 × Breadboard
• 3 × Push Buttons
• 3 × LEDs
• 3 × Resistors 220Ω (for LEDs)
• 3 × Resistors 10kΩ (pull-down for buttons)
• Jumper Wires

  Circuit Connections

  Buttons:
• One leg connected to +5V.
• Second leg connected to Arduino pins 2, 3, 4.
• Same leg also connected to GND through a 10kΩ pull-down resistor. LEDs:
• Anode connected to Arduino pins 8, 9, 10 via 220Ω resistors.
• Cathode connected to GND.
