ATL Binary Numbers Lab Kit
ATL Binary Numbers Lab Kit — Build a Toggle-Switch 8-Bit Binary Decoder
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Eight toggle switches put the binary system directly into a student’s hands, lighting up LEDs in real time to show exactly which decimal value the toggles represent. This kit is designed for ATL Tinkering Labs, CBSE computer science classrooms, and STEM exhibitions where the leap from textbook theory to physical understanding matters most.
What You'll Build
You’ll assemble a compact 8-bit binary decoder on a single perfboard. Flip any combination of toggle switches, and the corresponding LEDs glow to form the binary pattern. A reference chart on the board maps all 256 possible patterns to decimal numbers, letting students instantly see the conversion logic behind every 0 and 1.
What You'll Learn
- How an 8-bit binary number encodes values from 0 to 255
- Pull‑up and pull‑down resistor configurations for clean switch reading
- Translating LED on/off patterns into decimal numbers by position and weight
- Solderless prototyping with jumper wires on a perfboard

Who This Kit Is For
Teachers running ATL Tinkering Lab sessions will find this kit directly maps to data representation modules. CBSE Class 11–12 computer science students can use it to master binary arithmetic, while school science exhibition participants gain an interactive display that judges love. It’s also a ready-made activity for STEM clubs and Smart India Hackathon ideation workshops looking for hands‑on digital logic examples.
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.
What if I get stuck during the build?
The AI companion offers circuit‑by‑circuit photos and troubleshooting, and you can drop a WhatsApp message with a picture — we’ll reply with a fix within the day.
Can this kit be used for a school science exhibition?
Yes. The glowing LED array and toggle switches immediately attract attention, and the companion guide includes script notes to explain binary conversion to visitors and judges.
Do I need to solder anything?
No soldering is required. All connections use pre‑stripped M‑M jumper wires and a standard perfboard — assembly is completely reversible and safe for classroom use.
Does this align with CBSE computer science syllabus?
Absolutely. It directly supports data representation topics in Class 11 and 12, giving students concrete practice with binary notation and decimal conversion that reinforces textbook theory.
8 LEDs represent an 8-bit binary number — toggle switches to set bits and read the decimal value. Makes binary tangible.
