The Servo library supports up to 12 motors on most Arduino boards and 48 on the Arduino Mega. On boards other than the Mega, use of the library disables analogWrite() (PWM) functionality on pins 9 and 10, whether or not there is a Servo on those pins. On the Mega, up to 12 servo...

first 8 pins of the PCA9685 Pick one up today in the adafruit shop! ---> http://www.adafruit.com/products/815 These drivers use I2C to communicate, 2 pins are required to interface. Adafruit invests time and resources providing this open source code, please support Adafruit and open-sourc...
The ESP32 board has 16 independent channels that can generate PWM signals. Almost all the GPIO pins that can act as output can be used to generate a PWM signal. GPIO pins 34,35,36,39 cannot be used as PWM pins as they are input only Pins. In the 36 pins variant of ESP32 board t...
To generate a PWM signal on the ESP8266 pins with Arduino IDE, useanalogWrite(pin, value). The value is an integer between 0 and 255. For ESP8266 releases before 3.0, the default range is between 0 and 1023. The PWM range may be changed by callinganalogWriteRange(new_range). ...
Because the Arduino’s PWM pins has not enough ampe(I) to operate the motor, so we will base on transistor’s application to use the 5V of Arduino to control motor, about NPN transistor we have some popular types (C1815,2N2222,..) C1815 is used in the video. When we connect ...

Put a 10-50K pullup resistor on the pins you want to stay high. When the device resets, there is not going to be any signal delivered on those pins, so you need to provide a default one. You should choose a pin other than 12, which is a strapping pin that needs to be pulled lo...
