| Aug 12, 2016 at 9:32 | comment | added | user25642 | Well, I have two USB-Serial Converters, and I just tried them both. Sorry if that was confusing. And they both don't seem to work | |
| Aug 12, 2016 at 7:44 | comment | added | Code Gorilla | @user25642 - Has the COM port changed number or have I misunderstood. You program says COM3 yet you are connecting hTerm to COM7. | |
| Aug 11, 2016 at 15:02 | comment | added | user25642 | Ok, so I used hTerm for this, since this is probably better for debugging right now. When I send a signal from the Arduino Terminal to the Arduino via Serial(Works for both cases, virtual and builtin hardware serial port (Pin 0 (RX) and Pin 1 (TX), right?)), I get an answer in the seperate hTerm window. hTerm is connected to the USB-Serial Converter (COM7). However, if I'm sending data from hTerm or the ipython script to the Arduino, it doesn't respond. (The Arduino IDE terminal and hTerm show nothing). So, my best guess is that the USB-Serial Converter is broken... | |

| Aug 11, 2016 at 9:39 | comment | added | brtiberio | Does it work if you use the builtin hardware serial port of arduino? That way we could try to see if the problem is in the python part or the arduino part. | |

| Aug 10, 2016 at 17:44 | comment | added | user25642 | I updated the description. And that's correct, COM3 is the port that's assigned to the USB-Serial converter. And Pin 10 (RX) is connected to TX at the USB side, while PIN 11 (TX) is connected to the RX at the USB side. Also, I've already received data from the Arduino, so I don't think it's a problem with the setup. I've also switched around the connection cables, but that doesn't solve it either | |

| Aug 10, 2016 at 16:50 | comment | added | SoreDakeNoKoto | A diagram of your setup would add a lot of clarity to your question. You checked that the USB-Serial port is COM3? What does the Python shell display when you run the script? To be clear, you connected the RX of the USB-Serial adapter to Arduino pin 11, and its TX to Arduino pin 10? Remove the 'timeout' argument in the 'ser' instantiation in the Python script and try it again. | |
| Aug 10, 2016 at 14:22 | comment | added | Majenko | OK, that makes more sense to me now. | |
| Aug 10, 2016 at 14:21 | comment | added | user25642 | Oh, ok. Well, I'm connecting to Pin 10 (RX) and Pin 11 (TX). Or do you mean how I connect on the other end? | |
| Aug 10, 2016 at 13:53 | comment | added | Majenko | "Some cables" isn't very descriptive. Which TX and RX pins are you connecting to? | |
| Aug 10, 2016 at 13:38 | comment | added | user25642 | Some cables which came with the Genuino starter kit. RX is connected to TX and TX to RX (USB-Serial to Arduino), and ground to ground | |
| Aug 10, 2016 at 13:34 | comment | added | Majenko | What are you using to connect to the SoftwareSerial pins? | |
