From Blocks to Python: How CYFI Helps Children Learn Coding Without a Tutor
Coding and Robotics Shouldn’t Be Expensive or Inaccessible
For many families and schools in India, learning coding and robotics is still a challenge.
Quality programs are expensive, tutors are not easily available, and in Tier 2 and Tier 3 cities, access to structured robotics education is limited.
CYFI by Nesta Toys was built to change this.
CYFI is a self-learning coding and robotics platform designed so that a child can learn independently without a tutor, coaching centre, or expensive classes.
A Platform Designed for Independent Learning
CYFI teaches children from absolute scratch.
No prior coding knowledge is required.
The platform starts by explaining:
- What coding is
- What block programming means
- What each block does and how it works
Every concept is broken down in a way children can understand and apply on their own.
Step 1: Learn Coding Through Block Programming
Children begin their journey with block-based programming, where:
- Each block is explained visually and logically
- Tutorials show why a block is used, not just where to place it
- Children start by building simple programs and gradually move to more complex logic
CYFI encourages experimentation by allowing children to:
- Modify values
- Change logic
- Observe how outputs change
This builds logical thinking and problem-solving skills, even without teacher support.
Step 2: See Your Code in Action Using the Simulator
CYFI includes a built-in simulator that shows how code executes in real time.
When a child writes a block program:
- The simulator visually demonstrates how the program runs
- Children can see motors move, sensors respond, and decisions being made
This visual feedback helps children understand cause and effect, making learning intuitive and engaging.
Step 3: Smooth Transition from Blocks to Python and Arduino
Most beginner platforms stop at block programming.
CYFI is designed to take children beyond blocks.
Block to Python
- Every block-based program is reflected in Python code
- Children can see how visual logic translates into text-based programming
- Python becomes easier to understand because the logic is already familiar
Block to Arduino
- The same block logic is also shown in Arduino code
- Children learn how software controls hardware
By seeing block, Python, and Arduino code side by side, children naturally understand how programming languages work.
Step 4: Learn the Basics of Robotics Hardware
CYFI goes beyond coding by teaching children about hardware fundamentals, including:
- What different components do
- Where the controller (brain) is
- How sensors work
- Where plug points are and how connections are made
This helps children understand how real robots are built and function, not just how they are programmed.

Expert-Designed Courses with Certifications
All CYFI learning is organised into structured courses, designed by experts:
- Block Programming
- Transition from Blocks to Python
- Transition from Blocks to Arduino
- Basics of Robotics Hardware
After completing each course, children receive a certification, helping them track progress and build confidence.
Unlimited Learning Resources-Completely Free
One of CYFI’s strongest differentiators is accessibility.
- No paid subscriptions
- No locked tutorials
- No additional course fees
All tutorials, simulators, courses, and learning resources on CYFI are free to access.
This ensures high-quality coding and robotics education is available to:
- Parents
- Schools
- Children in Tier 2 and Tier 3 cities
Why Parents and Schools Choose CYFI
- Reduces dependence on tutors
- Makes robotics education affordable
- Enables independent learning
- Simplifies the transition to Python and Arduino
- Offers unlimited, structured learning resources
CYFI: Making Coding and Robotics Accessible to Every Child
CYFI by Nesta Toys is built on a simple belief:
Every child should have access to quality coding and robotics education-regardless of location or budget. By combining structured tutorials, simulators, hardware learning, and free access, CYFI empowers children to learn, experiment, and grow independently.
