Push Button LED Toggle Kit – Master digitalRead and Button Debouncing with Arduino Uno

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

What happens when you press a button? With this kit, you'll build a circuit where one press toggles an LED on, and the next press toggles it off. It's the perfect introduction to reading digital inputs with Arduino's digitalRead function and managing simple state logic. By the end, you'll have tackled debouncing, a real-world challenge every maker faces.

What You'll Build

You'll assemble a breadboard circuit with an Arduino Uno, two tactile buttons, and three LEDs. When you press button A, the first LED lights up; press again, it turns off. Button B controls the second LED, demonstrating independence. You'll also have a third LED that can be toggled by either button, illustrating how to manage shared state.

What You'll Learn

• Read digital inputs from push buttons using digitalRead
• Toggle output states with logical variables (state = !state)
• Handle button bounce through software debounce routines
• Wire components on a breadboard and understand pull-up/down resistors

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is perfect for CBSE Class 5-10 students curious about electronics, ATL Tinkering Lab members building their first Arduino project, and parents introducing STEM at home. It's also the ideal first step for B.Tech ECE/EEE students needing hands-on experience with digital I/O before more complex labs.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
