use a arduino to program a another arduino?


do anyone know if it is possible to use a arduino decimala to program a arduino from the ardunio environment clone that doesnt have the usb port? without that the software gets burnt in to the first arduino.

infact i just want to use the arduino as a usb to ttl serial interface and not effecting the hosting arduino?

Yes, you can do, have a look at the following links
