Required partsġ x resistor (can be any value between 100 Ohms and ~10K Ohms). 0 is LOW (no light), 255 is HIGH (full brightness), and 127 would be medium brightness, for example.

The brightness can be set anywhere between the range of 0 to 255. The analogWrite() function accepts a value (between 0 and 255) that represents brightness, rather than values HIGH or LOW.

You will also need to modify your code to use the analogWrite() function instead of the digitalWrite() function. To change the brightness of your LED, you will need to connect your LED to one of the six available PWM pins. The other digital pins do not support PWM output. These pins have a ~ symbol next to their number. The Arduino provides PWM (Pulse Width Modulation) that can output HIGH and LOW at different rates to adjust the LED brightness. However, only some pins on the Arduino provide PWM.

In this lesson, we will look at how to use PWM to adjust the brightness of an LED. In other words, the LED brightness is adjusted by changing the duration of lighting. This works by the Arduino repeatedly switching between the HIGH and LOW states to gradually increase or decrease brightness. However, you can use the Arduino’s PWM (Pulse Width Modulation) pins to adjust the brightness of the LED.

However, digital output can only be in either of two states - off or on (0 or 1) which means that you cannot adjust the brightness of the LED using digital output. Thank you in advance for your help.LEDs can be switched between HIGH (on) and LOW (off) states when they are connected to the Arduino’s digital pins. Serial.println('Movendo Servo: 90 -> 0')

There is also an LED connected to pin 12 for controlling commands. In the case of the board, a voltage reducer from 5.5v to 3.3v was fitted (connected to the board's VIN). The system is powered by a 5.5 v battery that supplies energy to the motors and the board. The circuit consists of an Arduino Nano IOT 33 board, an H bridge (L298N) connected to two DC motors, Servo Motor 180. To test the control of the motors I'm using the BlueLight app.

In addition to the servo motor, the robot is equipped with two dc motors that respond well to Bluetooth messages. I'm developing a bluetooth-controlled robot but I'm having trouble controlling a 180 servo motor.
