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.

Small Breadboard / Protoboard & 28-Pin (PDIP) IC socket – 1; Your Arduino UNO board (here used as a programmer) If you go through the Arduino IDE you can see an example sketch called “Arduino as ISP”.

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.

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 ...

All Arduino boards have this pin, and it's connected to the built-in voltage regulator that makes sure your board receives a stable supply. For the Nano, the VIN pin is found on Pin 30 (although ...
