Transistor Amplification – Arduino Workshop Project Video #2
This is the 2nd video in the Arduino Workshop tutorials series in which I show how to properly use a transistor to amplify a digital output pin. This is a must when you have to drive high current d. . .

Great video, but what are the pins for the transistor? I looked for the data sheet on the Radio Shack web site and couldn’t find it.
The transistor I used in the video has the same pin out as the one from Radioshack. Look at the flat and convex side of the transistor in the video.I don’t know why Radioshack doesn’t have them online but the diagram will be on the back of the package that they come in. It has tech specs about it as well as the basic pin out.Make sure you use the 2n2222 transistor because that “pack” of 15 only has 5 of them, the other 10 are different types. They will work but have different power ratings.
wow i ad no idea what a transistor was or did, but now i see what its for… and the white circuit thing where you plug everything into, where can you buy one? would one of those work for programming a set of leds that can strobe in various blinking patterns?
your a goose, but anyway your get a braed board(white thingy) from any electronics store!
The white board with all the holes in it is called a breadboard. It is used for rapid prototyping of circuits. You simply put component’s on the board and use wires and things to jump power around. This is a MUST HAVE and yes it will work for those LED’s. The blue circuit was the programmable part the white board was only for connecting it all together!You can get them at Sparkfun or ebay just search for “breadboard”. The ones on ebay are just huge w/ free shipping for a really low price!
O yea thanks to addzkebabs I just remembered that you can get them at Radioshack if you really need to go local or sometimes at hobby shops.However I would recommend that you DON’T go to Radioshack. It may be convenient but they will charge you like $20 for a breadboard that is slightly larger then the one in the video. If you go to ebay you can get one that is like 6 times larger, w/ free jumper wires and shipping for around $18!
Good stuff man.
Thanks
Thats pretty cool stuff man, thanx allot.
No problem!
