Arduino Dial Indicator Tutorial | Analog Meters & Gauge Displays
Give your Arduino project a retro analogue feel with a physical dial indicator or panel meter. This tutorial covers driving analogue VU meters, voltmeter panel gauges, and servo-based dial displays from Arduino using PWM and servo control.
🎛️ What you'll learn and more topics to research:
• Types of dial indicators: panel meters, VU meters, servo gauges
• Driving a moving-coil panel meter with PWM output
• Building a servo-based custom gauge display
• Mapping sensor values to dial position
• Project ideas: retro dashboard, audio level display, temperature gauge
