Pin No 9 10 11 Apr 2026

In many standard LiquidCrystal setups, pins 11 and 10 are the default choices for the Enable (E) and Register Select (RS) connections.

Pins 9 and 10 are hardware-linked to Timer 1 , a 16-bit timer that provides higher resolution for PWM compared to other pins. 🛠️ Hardware Specifications Pin Number Primary Function Special Feature Linked Hardware 9 Digital I/O 10 Digital I/O 8-bit PWM / SPI (SS) 11 Digital I/O 8-bit PWM / SPI (MOSI) ⚠️ Important Usage Notes Pin No 9 10 11

All three pins are capable of PWM output (Arduino Reference). This allows you to simulate analog results (like dimming an LED or controlling motor speed) using digital signals. In many standard LiquidCrystal setups, pins 11 and
