how can I read the ARDUINO without serialMonitor?

I just want to be able to connect to it and see the data that is printing
without the FTDI cable

So I connct pin0 & pin1 to my USB--Serial cable to my computer ,
open putty on the right com and the right rate (9600)
but I see garbage

when I open the MonitorSerial on the same Rate - I see everything just fine

what am I missing?

Thanks,

Have you tried changing the rate (19200) for example? i'm not an expert but i know changing the rates results in lots of random characters being displayed, so it might be displaying too slow/fast?
OR
maybe try swap pin1 and 0 around maybe its getting data the wrong way round?

Im no expert so sorry i couldn't help more :slight_smile: hopefully someone with more knowledge will be along soon!

So I connct pin0 & pin1 to my USB--Serial cable to my computer ,

TTL or RS232 serial?

You can't directly connect the TX/RX to a com port on a PC; levels are wrong and they are inverted. You need something like a MAX232.

TTL     RS232
5V      -12V
0V      +12V

Ohhhh

I thought the USB-cable do that ...

I have connected a TTL-RS232 and now it's working

Thanks! ,
