Pins (5V, 3.3V, GND, Analog, Digital, PWM, AREF) The recommended voltage for most Arduino models is between 6 and 12 Volts. NOTE: Do NOT use a power supply greater than 20 Volts as you will overpower (and thereby destroy) your Arduino.

More on how to program with Arduino can be found in our Installing and Programming Arduino tutorial. The USB connection is also how you will load code onto your Arduino board. In the picture above the USB connection is labeled (1) and the barrel jack is labeled (2). The Arduino UNO can be powered from a USB cable coming from your computer or a wall power supply ( like this) that is terminated in a barrel jack. Voltage, Current, Resistance, and Ohm's LawĮvery Arduino board needs a way to be connected to a power source.We recommend that you have at least a decent understanding of these concepts before you dive in to the wonderful world of Arduino.
However, you will have a much better time learning along side your Arduino if you understand some basic fundamental electronics beforehand.
What projects can be accomplished using an Arduino.
In this tutorial, we’ll go over the following: The code might not make perfect sense right now, but, after reading this tutorial and the many more Arduino tutorials waiting for you on our site, we'll get you up to speed in no time! You Will Learn Believe it or not, those 10 lines of code are all you need to blink the on-board LED on your Arduino.
