We have developed a comprehensive course on Arduino named “Arduino Course – Learn By Doing Projects”. Like to do an exciting course on Arduino with 12+ Projects? The fascinating feature in Nano is that it will choose the strongest power source with its potential difference, and the power source selecting jumper is invalid. This port is used for both programming and serial monitoring. The Nano board doesn’t have a DC power jack as other Arduino boards, but instead has a mini-USB port. The extra 2 pins of Arduino Nano serve for the ADC functionalities, while UNO has 6 ADC ports but Nano has 8 ADC ports. The main difference between them is that the UNO board is presented in PDIP (Plastic Dual-In-line Package) form with 30 pins and Nano is available in TQFP (plastic quad flat pack) with 32 pins. The Nano is inbuilt with the ATmega328P microcontroller, same as the Arduino UNO. How different is Arduino Nano?Īrduino Nano has similar functionalities as Arduino Duemilanove but with a different package. This article discusses about the technical specs most importantly the pinout and functions of each and every pin in the Arduino Nano board. The Nano board weighs around 7 grams with dimensions of 4.5 cms to 1.8 cms (L to B). The Arduino Nano, as the name suggests is a compact, complete and bread-board friendly microcontroller board. We’ve created a well explained, diagram based pin out representation of Arduino Nano. Then you restart the server and from its point there are magically new data or program or system or what you just did.In this guide, learn about Arduino Nano pin outs and diagrams. ISP - you take out the HDD from the server and simply store the dite directly on it, not asking any system for nothing.You can also picture the difference as this: - normal way - you open web page on server, put some data inside and politly ask the web page to store them somwhere - the page can do it or reject it o modify the data on the way and store them somwhere else, as the web page wish. So while normal programming works only with working bootloader and you can modify such bootloader to do things different way (or do nothing usefull at all, if you make mistake), the ISP goes directly to target HW and communicate with the HW, not with something you can change (like the bootloader).īy ISP you can upload anything anywhere and none program (good or botched) on target chip can prevent you from that. It happens behind curtain and Arduino does not know anything about it. Instead HW encoded pice of code communicate via MOSI (Master Out, Slave In) and MISO (Master In, Slave Out) pins, with timing done by CLOCK pin. While the reset is hold, Arduino does not work, none of your programs are running. On the other hand ISP programming first set RESET on target Arduino (or other chip) and holds it. Basically you are communicating with some program on Arduino and the program (which you can modify) stores some data to Arduino flash memory. When you send in the right commands, it read data from the serial connection (usually converted from USB (Universal Serial Bus) by ATmega8u2) and stores the received data to selected program memory. The normal way you program Arduino is serial, where on the Arduino is loader program (bootloader), which communicates with you. I would like to just add my point of view:
