🛠️ Arduino Round LCD Clock + Temperature Tutorial (DS1307 + DS18B20) ⏱️🌡️
In this quick 4-minute tutorial, I show you exactly how I built a real-time clock and temperature display using a 1.28" round ST7789 LCD, a DS1307 RTC, and a DS18B20 temperature sensor — all driven by an Arduino.
🔌 What you'll see in this video:
Full wiring guide for the display, RTC, and temp sensor
Step-by-step code walkthrough using the Waveshare LCD library
Live demo showing time and temperature updates every second
How to get crisp graphics on the 240x240 round screen
This is a great weekend project for makers who want to build a slick clock with a clean visual layout using familiar components and a beautiful circular display.
📦 Components used:
Arduino Uno/Nano
DS1307 Real-Time Clock
DS18B20 Temperature Sensor
1.28" Round LCD with ST7789 driver
4.7kΩ pull-up resistor (for the DS18B20)
