It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog. 1)Objective. Minimal Arduino is similar to my previous DIY Arduino board, schematic and PCB as shown in Fig 1. The 4x4x4 LED Cube (Arduino): In this instructable I will show you how to make a 4x4x4 LED cube that will be controlled by an Arduino Demulionove. now yes you might say" that Arduino has only 14 I/O pins well also the 6 analog pins can be used as pins 15,16,17,18,19,20. In this project, we will be interfacing the DS3231 Real-Time Clock (RTC) with an Arduino Uno. How to set the clock frequency? please help with codes. Plug the SCL pin into your Arduino Uno A5 port,. I2C slave devices have no minimum working clock frequency, however 100KHz is usually the baseline.
