Hello there, today i got my arduino uno ! Great success with the blink example YEEEEEEEEAHH :P , but now lets go to some serious (just for me) issues. My project will require an external power supply , i cant have arduino connected to usb cable, so im searching an external power supply !
I will use : (at the right im writing the V and A i THINK each piece wants)
1x - https://www.sparkfun.com/products/11021 5V @ ?A (im not sure for 5V either , it says 7-12V but usb is 5V right ? why external of 5V whouldn't work ?) 2x - https://www.sparkfun.com/products/9648 5V@0.2A x 2 = 5V@0.4A 2x - https://www.sparkfun.com/products/10167 5V@0.0016A x 2 = 5V@0.0032A 1x - https://www.sparkfun.com/products/9395 5V@ up to 1A , so 1A 1x - https://www.sparkfun.com/products/8653 5V@?A 1x - https://www.sparkfun.com/products/9607 3.6V@2A - here it says to put 5V http://tronixstuff.wordpress.com/2011/01/19/tutorial-arduino-and-gsm-cellular-part-one/ 40x - https://www.sparkfun.com/products/9590 2.2V@0.02A x 40 = 2.2V@0.8A , through https://www.sparkfun.com/products/733
Future thoughts :
Non-Future thoughts = ?+0.4+0.0032+1+?+2+0.8 = 4.2A Future thoughts = 4.2 + 0.7 = 4.9A
In order to get 3.6V and 2.2V i will use some kind of regulator or another 2 different power supplies ? THANKS !
