There are six pins on the Arduino Uno (shown below A0 ~ A5) that can be selected for an ADC measurement; A multiplexor feeds one of the six analogue input pins into the ADC. Use the function: analogRead(pin) Setting of the multiplexer is done in that function for you automatically. ...
In this DIY guide we see how to make your own Arduino aquarium auto lighting system. The creator decided to make his own PCB that is based on Arduino UNO microcontroller - Atmega328p. You will find the electronic schematic with PCB layout so you can easily produce it. ...
This library can be quite heavy on small systems, especially if the fairly small ATmega 328p (such as in the Arduino Uno) is used. In the default configuration, the available 32K flash space is nearly filled up (this includes some debug output overhead, though). By disabling some features...
and which board will you be using, mega adk or uno+usb host shield2.0; and if you are using a pend drive/usb hard drive, you will also need a power adapter connecting the arduino board because the laptop/ pc power supply to the 5v arduino board will not be enough ...

The best known of this new line of chips (among hobbyists, at least) is the ATmega4809, used on the Arduino Uno WiFi Rev.2 and Nano Every. However, there is also an extensive line of tinyAVR parts based on this new architecture, ranging from 8-pin to 24 pin packages, with up to...
