24+ Arduino Uno Pin Diagram Images
Background. So you have 6 pins where you can create a pwm, using the analogwrite() function. Only digital pins 2 and 3 can be used as.
Arduino Uno R3 Microcontroller Specifications And Pin Diagram from www.elprocus.com
System has been designed and implemented based on two components which is hardware and software. As mentioned earlier uno got 6 analog input pins but arduino nano has 8 analog inputs (19 to 26), marked a0 through a7. So you have 6 pins where you can create a pwm, using the analogwrite() function.

Arduino may make changes to specifications and product descriptions at any time, without notice. This means you can connect *8. It has 14 digital input/output pins, 6 analog inputs, a 16 mhz quartz crystal, a and the next pic clearly specify the pin diagram of atmega168 ic which is the main thing which controls the working of arduino uno board. When atmega328 chip is used in place of arduino uno, or vice versa, the image below shows the pin mapping between the two.
