Discovery Phase: Hello World of Hardware
Students with zero prior experience progress from understanding basic electronic components to writing Arduino programs that interact with the real world. Aligned with CBSE Class 7 Science chapters on electricity, motion, and temperature.
No prior coding or electronics experience required. Students should be comfortable with basic Class 6 Mathematics.
Kit Cost
₹1,800–₹2,200 per student
Sessions 1–18
From zero electronics knowledge to building a Weather Station that reads temperature and light levels with Arduino.
Module 1: What is a Robot?
Conceptual understanding of robotics — where students encounter robots daily, types of robots, and the engineering design process.
CBSE Link
Foundation building
Module 2: Electricity Basics
Fundamental electrical concepts through hands-on circuit building. Students build a 3-LED Traffic Light Simulator using only battery, resistors, and switches — no Arduino yet.
CBSE Link
Ch 14: Electric Current and Its Effects
Module 3: Arduino Programming Basics
Transition from manual circuits to programmable ones. Students learn setup(), loop(), digital/analogWrite, and control their first LED through code.
CBSE Link
Computational thinking
Module 4: Sensing the World
Reading sensor input — LM35 temperature sensor, LDR light sensor. Capstone: Weather Station v1.0 that reads temperature and light every 5 seconds.
CBSE Link
Ch 4: Heat & Temperature
Sessions 19–36
From passive sensing to active control — motors, autonomous behaviour, and the Smart Dustbin capstone.
Module 5: Motion & Motors
Creating motion with servo and DC motors. Project: Speed Calculator Robot — students measure distance, calculate speed = distance/time, and plot PWM vs. Speed graphs.
CBSE Link
Ch 13: Motion and Time
Module 6: Intelligent Behaviour
Robots start making decisions based on sensor input. Conditional logic (if/else), combining sensor readings with motor control for autonomous behaviour.
CBSE Link
Logic & decision-making
Module 7: Creative Projects
Self-directed creative projects applying everything learned. Year-End Capstone: Smart Dustbin — HC-SR04 detects hand within 15cm, servo opens lid, auto-closes after 3 seconds.

All year concepts combined
What students build in Class 7
Traffic Light Simulator
Build a 3-LED traffic light using only battery, resistors, and manual switch. No Arduino — students understand circuits fundamentally.
Components
9V battery, 3× LEDs (R/Y/G), 3× 220Ω resistors, push buttons, breadboard
Weather Station v1.0
Reads temperature and light every 5 seconds, prints to Serial Monitor, triggers LED warning if temp exceeds 35°C.
Components
Arduino Uno, LM35, LDR, breadboard, jumper wires
Speed Calculator Robot
Robot drives forward, students measure distance, calculate speed = distance/time for 5 different PWM values.
Components
Arduino, DC motor, wheels, battery, ruler, stopwatch
Smart Dustbin (Capstone)
Hand detected within 15cm → servo opens lid. No detection for 3 seconds → lid auto-closes. Year-end capstone.
Components
Arduino, HC-SR04 ultrasonic sensor, servo motor, cardboard bin
