In this video, I’ll show you how I built a compact, rechargeable tachometer using an infrared sensor and OLED display. This RPM counter is ideal for measuring motor speed in DIY electronics and robotics projects. We'll cover the components, circuit design, 3D-printed case, and Arduino code!
🔧 Features:
IR-based RPM detection
Rechargeable via Type-C
Compact 3D-printed enclosure
OLED display
📦 Parts Used:
IR Sensor Module (Obstacle Avoidance Sensor)
OLED Display (128x64 I2C)
Arduino Nano
TP4056 Charging Module
3.7V Li-po Battery
3D Printed Case
