How to fix a cp2102 usb to TTL serial adapter to automatically program a hackduino that you built yourself that is lacking an on-board USB adapter.
I was having to press the rest button on my home build arduino board in order to allow it to accept the programming from the arduino software program. This took some timing, and is just annoying. So I finally looked up on the Google how to fix the problem.

| 1. Cut the trace. |

| 2. Solder a jumper from dtr to the reset pin. |
Step 2 could also replace the jumper wire with a .1 uf capacitor. A capacitor turns a low state into jus a single pulse.
This would save the cost of having a capacitor added to each board. I go ahead and put the capacitor on each board anyway, so no capacitor needed here.
