: Includes a Power LED and a Pin 13 "L" LED pilot.
Let’s solidify the manual with a real project. You will build a radar-like sensor that sweeps a servo back and forth while reading an ultrasonic sensor.
The Arduino Uno has limited current (approx 500mA via USB). If you stack a Sensor Shield + Motor Shield + 3 Sensors, you will brown out. Use a separate 5V BEC (Battery Eliminator Circuit) connected to the shield’s 5V header (but cut the trace to the Arduino’s 5V pin first).
