![]() ![]() I'll go through all these links and see what I can do.Ī couple notes, Surprisingly this sensor is spot on in terms of my location from inside my house. I watched a tutorial on youtube and the guy said it was 3.3V only, however I did not confirm that myself! For mixing micros and modules of different voltages that aren't internally setup to use multiple voltages you need a logic level shifter. Some modules can handle 5V and 3.3V when fed with 3.3v they will output 3.3v logic. You can attach a 3V module to a 5v arduino but if you do you need to make sure your arduino does not fry that module. A module that works at 5V and gets fed 5V from your arduino will in turn do the same, output 5V for high and 0 for low. The data pins on it will when opening them as OUTPUT measure 5V for "HIGH" or "ON" and 0V for "LOW". ) Your arduino uno, although having a 5V and a 3.3v pin that can be used to power various things is itself a 5V logic board. Next to that there are 3.3V and 5V modules out there ( like your gps module is one of them but there's temperature sensors and gyroscopes etc. There are other 3.3v micro boards out there as well, the popular esp boards for example. There are 5v logic arduinos and 3.3v logic arduinos out there. Println adds extra eol characters 10 & 13. Why "write" and "read" and not print and println. Serial.write(mySerial.read()) // read it and send it out Serial MySerial.write(Serial.read()) // read it and send it out mySerial ![]() ![]() In your case it would be a softserial port instead of Serial1.ĮDIT: Quote from link (edited for your sketch) void setup() Make a program on your arduino that gets data from serial and writes it to softserial and vice versa. If you don't have an usb to serial cable you can connect your gps module to a softserial port ( emulated serial using 2 other pins ). You can use an usb to serial cable on your pc and download the u-center app to see a graphic representation of those "*** LOTS OF NUMBERS BUT DELETED DUE TO PROBABLY BEING GPS COORDINATES ***" My experience with GPS modules is that they only work well outside in a quite open area for best results. Is this guy in the link below using 5V? You could have a different module however. It might still work like this but I'm just putting it out there.* is that module 3.3v only? Can I see a pic? if it's 3.3v & 5V you should use 5V since your arduino's logic pins work at 5V. I am hoping your arduino is connected to that green wired ground I see drawn on there as well.Īlso. I guess my next question is.using the hardware serial port it was giving me strings before the signicant data, like $GPLLĮDIT 2: Ok I stored the data from mySerial into a char and then printed the char variable to the serial monitor. NOTHING367180 *** LOTS OF NUMBERS BUT DELETED DUE TO PROBABLY BEING GPS COORDINATES *** 110 I switched the TX and RX pins on the arduino and got something: NOTHING Also, I am able to read data from the sensor when I upload a blank sketch to the arduino and connect directly to the hardware serial port on the arduino.ĮDIT: Ok.update. One note, I guess this sensor has the TX go to the arduino's TX, and RX to arduino's RX. However, I never get anything from mySerial. Then I want to read the sensor data into a variable and parse the data and go from there. My goal right now is to simply print what's coming in from the sensor to the Arduino's serial monitor.
