Pi Pico W LED Matrix Clock
Build a WiFi NTP Clock with Scrolling Temperature Display Using Raspberry Pi Pico W
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a dual 8x8 LED matrix display that shows the current time fetched from internet time servers over WiFi, and automatically scrolls the ambient temperature from a DHT22 sensor. This project combines internet connectivity, sensor readings, and visual output into a single, functional desk clock that gives you real-world IoT experience while creating something you’ll actually use every day.
What You'll Build
You’ll assemble and program a connected timepiece that automatically syncs over WiFi, displays the time in large digits across two LED matrices, and scrolls the temperature every few seconds. The result is a compact, network-aware clock that’s both a practical gadget and a foundation for more advanced IoT displays.
What You'll Learn
- Flash MicroPython firmware onto Raspberry Pi Pico W and connect to WiFi
- Retrieve accurate time from NTP servers and format it for matrix display
- Drive MAX7219 LED matrices using the SPI protocol and display scrolling text
- Read DHT22 temperature sensor data and integrate it into the scrolling loop

Who This Kit Is For
This kit is ideal for CBSE Class 11–12 students building IoT projects, B.Tech ECE/EEE undergraduates exploring embedded systems, and participants in Smart India Hackathon who need a reliable internet-connected display. ATL Tinkering Labs and hobbyists wanting to move beyond basic Arduino projects will find it a perfect next step.
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 QR code on the box to access the AI companion trained on this exact kit, or reach our support team via WhatsApp for real-time guidance.
Will the clock keep time if the WiFi connection drops?
Once synced, the Pico W maintains time using its internal timer, but long-term accuracy will drift without periodic NTP updates. It's designed for always-on WiFi environments.
Can I modify the code to display custom scrolling messages?
Absolutely. The MicroPython code is structured to easily edit the scrolling text — you can add custom greetings, sensor readings, or any ASCII messages.
Do I need soldering for this kit?
No soldering is required. All components connect via jumper wires onto a breadboard (not included). The kit assumes you have a standard breadboard and a computer with USB.
MAX7219 8x8 matrix shows time fetched from NTP over WiFi. Scrolls temperature from DHT22.
