Touchless Smart Tap Kit - Arduino Waste Sorting STEM Project
Touchless Smart Tap Kit v2 - Arduino-Powered Waste Sorting for Beginners
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform bathroom waste handling into a hands-on robotics lesson. This kit lets young makers build a touchless system that automatically detects an object's colour and diverts it to the correct bin using IR sensors and a servo mechanism - simulating a smart hygiene station with real sustainability impact.
What You'll Build
You'll assemble a tabletop waste sorting station that mimics a touchless smart tap. When an object is placed near the detection zone, the IR sensors trigger the TCS3200 colour sensor to identify red, green, or blue waste. Two SG90 servos then rotate the sorting flap, directing the item into the right bin. The result is a fully functional prototype you can test with coloured paper or small tokens, proving how automation can improve hygiene and recycling adherence.
What You'll Learn
- Wiring and reading analogue data from a TCS3200 colour sensor
- Using two IR sensor modules to create a proximity trigger
- Controlling SG90 servo motors with PWM signals on Arduino
- Writing conditional logic for waste sorting based on colour thresholds

Who This Kit Is For
CBSE Class 11-12 students working on robotics or sustainability projects, ATL Tinkering Lab members exploring sensor-based automation, and young hobbyists aged 10-15 eager to see how coding directly controls hardware. The kit turns abstract environmental concepts into a working model, ideal for school exhibitions, science fairs, or simply building confidence with Arduino.
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?
Scan the included QR code to launch the AI companion, which gives real-time troubleshooting specific to the Touchless Smart Tap wiring and code. You can also message us on WhatsApp for human backup.
Does the kit include a power adapter for the Arduino?
The Arduino Uno R3 is powered via the included USB cable connected to any 5V USB charger or laptop. A standalone adapter is not needed.
Can I expand the project to sort more colours?
Yes, the TCS3200 can detect a wide spectrum. You can modify the code to add categories like yellow or re-program the servo angles for more bins, using the same sensors.
Is soldering required?
No soldering at all. All connections are made using the breadboard and jumper wires provided, making it safe and reversible for beginners.
Bathroom - IR and colour sensors identify object type and a servo diverts it to the correct bin - practical robotics for STEM sustainability.
