Grade 3 STEM Activities: Blinking LEDs with Cayo Board Using RoboSiddhi
Grade 3 STEM activities help children explore science, coding, robotics, and electronics through fun hands-on learning. STEM stands for Science, Technology, Engineering, and Mathematics, and these activities encourage children to think creatively and solve problems practically.
In this exciting Grade 3 STEM activities project, children learn how to make LEDs blink using the Cayo Board and RoboSiddhi software.
This beginner robotics coding project introduces important concepts such as:
- LED programming
- Loop programming
- Delay timing
- Robotics basics
- Block coding
The project helps children understand how coding controls lights and electronic devices in robotics systems.
What is LED Blinking?
LED blinking means turning lights ON and OFF repeatedly at regular intervals.
The blinking effect is similar to:
- Human eye blinking
- Twinkling stars
- Traffic lights changing colors
This Grade 3 STEM activities project helps children understand how coding controls timing and repeated actions in robotics.
Materials Needed
This beginner robotics project requires:
- Cayo Board
- USB Type-C cable
- Computer or laptop
- RoboSiddhi software
These materials help students perform coding and electronics experiments safely and easily.
Connecting the Cayo Board
Step 1: Connect the USB Cable
Use the USB Type-C cable to connect the Cayo Board to the computer.
Step 2: Check the Green Light
When connected successfully, a green light appears on the board.
This indicates the board is connected properly.
Step 3: Open RoboSiddhi Software
Open RoboSiddhi software on the computer.
Students can use:
- Block-based coding
- Python programming
This project uses beginner-friendly block coding.
Understanding Setup and Loop
This Grade 3 STEM activities lesson introduces children to important coding concepts.
Setup Section
The setup section runs only once when the program starts.
It is used for:
- Initial settings
- Starting devices
- Hardware configuration
Loop Section
The loop section runs continuously again and again.
It controls repeated actions like:
- LED blinking
- Robot movement
- Repeating sounds
Children learn that blinking LEDs must be controlled inside the loop section.
How to Make LEDs Blink
Step 1: Turn LEDs ON
Use the “Set All LEDs” block and select a color like red.
Step 2: Turn LEDs OFF
Select black color.
Black means the LEDs are OFF.
Step 3: Add Delay
Insert a delay block between ON and OFF states.
For example:
- LEDs ON for 1 second
- LEDs OFF for 1 second
Step 4: Place Everything Inside the Loop
The loop repeats the process continuously.
This creates the blinking effect.
Science Behind the Blinking LEDs
This Grade 3 STEM activities project teaches children how timing and coding work together.
The microcontroller receives coding instructions and controls:
- LEDs
- Timing intervals
- Repeated actions
Children learn that:
- Delay controls timing
- Loop controls repetition
- Coding controls electronic devices
This helps students understand basic robotics and electronics concepts practically.
Real-Life Examples of Blinking Lights
Blinking LEDs are used in many everyday technologies.
Traffic Lights
Traffic signals use timed lights to control traffic safely.
Decorative Lights
Festival and decoration lights blink continuously using programmed timing.
Emergency Vehicles
Police cars and ambulances use blinking lights for alerts and visibility.
Electronic Devices
Many electronic devices use blinking indicators to show notifications or activity.
