If your board has no printed labels, check out its pinout diagram documentation (found on the board's Arduino Store page). PWM pins in the diagram have the same tilde sign in front of the pin numbers.

The analog sensor on the Arduino board senses the voltage on the analog pin and converts it into a digital format that can be processed by the microcontroller. Here, we are feeding the input voltage ...

Out of the box, the BeagleBone Black includes a single DC power barrel connector, two USB 2.0 ports (one micro USB), a micro SD card slot, a micro HDMI port for video output, and a 10/100 Ethernet ...

Connect one of the servo’s yellow signal wires directly to Arduino pin 9, and the other servo’s signal wire directly to Arduino pin 10, as shown in the circuit diagram in Figure 10-4. 3.
