Vinson Particles Serial Port
I'm very new to Arduino so apologies if this is a naive problem.My goal is to read and record RS232 output from a balance. I have the Arduino (with an SD shield) and an RS232 to TTL converter (this model: hooked up as in the attached diagram (TX - Pin 0, and RX - Pin 1).

I have the following sketch (attached) which should simply write the RS232 output to the SD card.However, when I check the serial monitor the following appears:Initializing SD card.card initialized.Arduino Gotcha:00Arduino Gotcha:00Arduino Gotcha:104104Arduino Gotcha:00Arduino Gotcha:1616Arduino Gotcha:11Arduino Gotcha:33Arduino Gotcha:1212Arduino Gotcha:00Arduino Gotcha:00Arduino Gotcha:00It appears the Arduino is getting a signal from the RS232, but it's gibberish. I've tested the RS232 output by hooking it up to my computer - the output is fine.I've combed through the forums and google but am completely stumped. Does anyone have any suggestions?Thanks,-Greg. I double checked the baud rate (9600), Data bit (, Parity (None) and Stop bit (1) - they match between the Arduino and output from the balance.I've hooked my set-up to my PC but am unsure how to 'type in something' into the port (I tried googling to no avail) - any pointers? For what it's worth, when I plug/unplug the set-up to the PC I get a signal ('Arduino Gotcha: 0').
If I leave the set-up as is, then it's a continuous stream of zeroes. Here is an example of what I mean:00000Arduino Gotcha:0 //I unplugged the set-up here000Arduino Gotcha:0 //I plugged the set-up back in here, etc.0Arduino Gotcha:00Arduino Gotcha:00Arduino Gotcha:00Arduino Gotcha:00000I should also clarify: the output from the balance is ASCII format. The message I receive successfully on the PC is 'W: +45.81' (or whatever the weight is). Can the Arduino deal with ASCII format? I am guessing that your SD is on a shield so you don't know what pins it uses.

10 and 11 are two of the SPI pins and SD uses SPI. I know because my SD is on a module, I have to stick the jumpers in and I'm looking at an UNO with SD, 10 to 13 + GND are filled. I've gone with 2 and 3 for soft serial with SD.Also there's a debug technique we use when we're not sure what the code is doing. We print short messages to serial monitor from different places in the code to show us what path the code took and what critical values we want to know. It can work very well, check yourself this way as well as your code.When you have SD, you can log run data to that.
If there's a problem, you might have data on how it got there. Liudr: thanks!
I've changed the code as you suggested. I've got my PC triggering a response on the Arduino.

When I send a message via the Terminal program it triggers the 'Arduino Gotcha: n' in the Arduino terminal window. However, the message is not received properly - it either spits out a '0' or (sometimes) a single, double, or triple digit number in the terminal window. I am unsure why the message is not received properly - any ideas?GoForSmoke: Thanks for the info about the SD shield (pins 10-13), I did not know that. Following your suggestion, I've modified the.ide for soft serial use on pins 2/3.
Please note, this code is a modification on what I described for liudr since he suggested not using soft serial and (I think) using the default pins 0/1 (although xkimi pointed out, this can cause issues with the SD shield).
