As the name would suggest, the Arduino Nano is a more compact board,designedto provide very similar functionality to the Arduino UNO andDuemilanove –only in a smaller, more space-efficient package. It utilizes amini USBconnector, compared to the standard size, and doesn’t require anexternalpower source. Rather, the efficient design allows for the singleconnector tosimultaneously provide power as well as access to themicrocontroller. Based on the ATmega328 chip, the breadboard-friendly Arduino Nano offersatotal of 14 digital I/O channels, 6 of which are PWM I/O, as well as 8analoginputs. The board runs a 16MHz Crystal Oscillator and utilizes 32kB offlashmemory – with 2KB reserved for operating the bootloader. The primary difference when comparing the Nano to the UNO is that theNanooffers two extra I/O pins, a higher clock speed and better storagespace.Additionally, while the UNO was designed for beginners to easily learnandutilize, the Nano is more suited to advanced users. Arduino Nano - Technical Specifications:| – ATmega328 - Operating Voltage (Logic Level)
| – 5V - Input Voltage (Recommended)
| – 7 to 12V | – 6 to 20V | – 14 (of which 6 provide PWM Output) | – 8 | – 40mA | – 32KB (2KB is Reserved by Bootloader) | – 2KB | – 1KB | – 16MHz | – 43.1 x 18.5mm | – 7g Typical Applications for the Arduino Nano:Because of the sheer versatility of the Arduino Nano, the list ofapplicationsand uses is almost endless. From simple displays of numbers, wordsor otherLED and LCD imagery, all the way through to motion-sensor securitysystems,you will certainly be able to find a fun or practical use for itsomewhere inyour home. Some fun home-project applications include: - Multi-LED displays
- Motion or sound-based alarm systems
- Hand-gesture interpreters
- Self-tuning radios
- Motion-activated water guns
- Remote controlled cars
Advanced tinkerers and inventors can also take these boards even further,withsome more complex (and more exciting) projects including: - Small robots and robotic buddies
- Connecting home electronics to social media or online platforms
- People-counters to sense and display the amount of people who pass by
- Temperature and humidity monitors
- Gyroscopic movement sensors
- The open-source “Arduino Glass”, which is similar to the Google Glass digital face accessory
These are just some of the amazing projects that the Arduino Nano canbeutilized for, although even as you read this, even more ideas arebeingintroduced thanks to the versatility and functionality of this complexboard. _ *Note: This is not supplied by Arduino, although it is manufacturedtothe same specs and quality controlled locally to ensure it functionsexactlyas expected - while saving you money._ __ |
