I was wondering if it could be possible that I can use a laptop Pentium 3 with USB v1.1 to program an arduino uno R3?
I'm not sure since USB v1.1 (1.5 Mbit/s) is very slow compared with USB 2.0 (480 Mbit/s)
How much Mbit/s do I need to program an arduino uno R3?
Could it exist another reason why I shouldn't use an USB v1.1?
The reason is that I want to bring back to life my old laptop Pentium 3 (it has only one USB port v1.1) to play with arduino
Thanks in advance.
You can do that. Arduino UNO has a memory of 32Kb,at the speed you are telling,it'l be filled in fraction of seconds,but that dosent happen. A chip on arduino board converts USB signals to SERIAL. In short,you can use your P3 laptop.
USB 1.1 supports FULL SPEED USB, 11 Mbps or so, which is as fast as the arduino will go anyway.
However, a laptop that old may not support a new enough version of Java...
WinXP SP3 supports java enough for Arduino 1.6.8 and processing 3
