Pei Hwa Hackathon 2026 challenges participants to take an active role in shaping the future by developing
forward-thinking, sustainable, and impactful solutions.

Hackathon Overview

Innovating with Kindness:
Caring for People and the Planet

In an increasingly complex and fast changing world, innovation is no longer just about advancing technology. It is about advancing humanity. As we navigate challenges such as climate change, social inequalities, and rapid technological growth, there is a growing need to design solutions that are not only effective, but also compassionate and responsible.

While globalisation and technological progress continue to connect Singapore to the world, they also bring pressing questions. How might we care for vulnerable communities? How can we protect our environment while continuing to grow? And how can innovation be used as a force for good?

This year’s theme invites participants to reimagine innovation through the lens of kindness, placing people and the planet at the heart of every idea. It calls for thoughtful, human centred solutions that uplift communities, promote inclusivity, and contribute to a more sustainable future.

The Pei Hwa Hackathon 2026 is more than a competition. It is a platform for young changemakers to design with empathy, act with purpose, and create meaningful impact. Because the future we build should not only be smarter, but kinder.

Hardware & Software

Components & Kit

A microcontroller is a small, programmable device that can be used to control or automate simple tasks. It works by receiving input from its surroundings, processing that information based on instructions you give it, and then triggering specific actions. Microcontrollers are often used in projects to help students learn how to think logically, solve problems, and create interactive solutions. They’re useful for building prototypes, experimenting with ideas, and learning how technology can be applied in everyday life.

For Pei Hwa Hackathon 2026, participants are given the option to choose between ‘Micro:bit’ or/and ‘Unihiker’ as their microcontroller for their project. Both microcontroller consist of various features, please refer to the following for the technical specifications.

Option #1
Micro:bit + External Components

Image above for reference. No kit will be given for this option.

You are not limited to the number of external components used with the microcontroller. Please view the next section (learning tutorials) for basics on using micro:bit.

There are no installation required for this option and students can achieve their coding (block-based/syntax) on makecode.

Option #2
Unihiker + External Components

Only this kit will be distributed to confirmed participants
Kit consists of the following:
  • 1x Unihiker (microcontroller)
  • 1x Servo Motor (180 deg)
  • 1x Ultrasonic Sensor

Project examples

Real-life Applications

Micro:bit v2 + Soil Moisture Sensor + Water Pump

Wireless Soil Moisture Monitoring

This project uses the micro:bit to create a wireless soil moisture monitoring and irrigation system. Multiple sensors send data to Microbit (1), which transmits it to Microbit (2) for display.

 

Each LED column represents one sensor, allowing multiple plants to be monitored, and a water pump can be activated automatically when the soil is too dry.

Smart Food Waste Monitor

The Smart Food Waste Monitor is an innovative system designed to reduce food waste in schools and homes using Artificial Intelligence (AI) and Internet of Things (IoT) technology.

 

It encourages users to be more mindful of how much food they take and helps track waste patterns over time.
