Скачать или смотреть DIY Arduino Clock Pendulum Timer | Precision Timekeeping for Horologists

This was the very first version of my pendulum beat timer — a simple Arduino-based setup to help me fine-tune mechanical clocks with a bit more accuracy than I could manage by eye alone. It’s a straightforward build using an infrared sensor and some basic code running on an Arduino Uno. Please check out my most recent video in which I have updated the design and structure of this build!

📋 What this version does:
Measures pendulum beat intervals in real time
Displays drift in seconds per hour
Calculates moving averages to reduce noise
Uses a basic OLED display and serial monitor for data readout

At this stage, I wasn’t aiming for extreme precision — just something that would help me get my clock as close as possible before moving to more refined timing methods. After just a few minutes of tuning, I was already getting drift under a second per hour, which felt like a good step forward.
