CASE ANALYSIS
Scenario
You need to wire up a two-axis pan-tilt turret with standard SG90 servos and an Arduino Uno for projects like camera tracking or light following.
Key decisions
- Using Arduino pins D9 and D10 for pan and tilt PWM signals
- Powering both servos from the Arduino’s 5V pin shared through the breadboard’s top rail
- Dedicating the top and bottom rails for power and ground distribution
When to reuse this
Use this wiring when building a simple pan-tilt mount without an external servo power supply, provided the total servo current draw is within the Arduino’s 5V regulator limit (typically <500 mA for small servos like the SG90).
