Review: build a controller for a roll off roof observatory - I bought this to build a controll board to operate my roll off roof observatory with NINA. I saw on you tube how to build this and bought the parts here on desertcart. after building the controller I can now use NINA advanced sequence to controll my roof in my observatory, so that means when I'm sleeping my scope is taking pictures and when it is done NINA sends a signal to this Arduino and it relays it to my motor controller and it closed my roof.... pretty neet...
Review: Powerful board for the beginner or advanced computer hobbyist - I found the Arduino Uno to be a well crafted piece of equipment. The reason I got one was to create a pendulum like motor with a mini servo. Having never touched anything like this before, a few google searches led me to understand that this board could do exactly what I wanted. There is documentation galore. I found it to work well and my PC (Windows 7 Home Prem) found the driver immediately, which allowed me to get to work quickly. If you are looking at a product like this, then you probably have some idea what you want to do with this before getting it. As such I gave it a 5 out of 5 because it did exactly what I needed it to. I am sure there is tons of potential here for other bigger and better things to me created from this board. As far as basic programming goes the compiler and anything else worked quite well. I recommend this product to anyone that needs to create a "robot" in a very basic fashion, or to somebody just looking to experiment. The price is good and the potential is nearly infinite. Obviously people that are really into this might ask for different features, but that is what other versions of the Arduino are for. Pros: + Price + Simplicity + Well-crafted Cons: - None that I can give with my experience so far. Excellent little board that can fit many needs.

## Questions & Answers

**Q: Arduino UNO smd v3. Vs arduino uno v3 .What is the difference**
A: The difference between the two Arduino UNO module is the ATMEGA MPU chip. The Arduino UNO uses the DIP version of the chip and the ARDUINO SMD version uses a surface mount ATMEGA chip. Function wise, there is no difference. The only advantage on using the ARDUINO UNO with a DIP style ATMEGA chip is you can replace the chip, while the ARDUINO UNO SMD version you cannot replace the chip.

**Q: Does it come with USB cable?**
A: Nope.  No cable.

**Q: Are these items suitable for brilliant 14 year old boy?**
A: Absolutely!  I recommend also purchasing a solderless bread board and a set of"3 x 40P 20cm Dupont Wire Jumper Cable 2.54 1P-1P Male-Male/Female-Female/Female-Male "Note that you might also want to purchase a 9v power supply (look at the "Frequently Bought Together" list).

**Q: What is the xtal frequenty?**
A: Crystal Oscillation is a t 16.000 MHz.
