פענחו את ההחלטות שמאחוריו.
01
Using Arduino pins D9 and D10 for pan and tilt PWM signals
02
Powering both servos from the Arduino’s 5V pin shared through the breadboard’s top rail
03
Dedicating the top and bottom rails for power and ground distribution
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).
