Im now currently working on the “Vehicle Monitoring System Using Blynk…” project. Im using Arduino Uno, GPS Shield and want to use the USB to connect the arduino with internet. The problem now is I cannot get the GPS data(its like not working) if i put “Blynk.begin(Serial, auth);” at void setup() section. Then, to make the GPS working as usual, the “Blynk.begin(Serial, auth);” was add comment to it…Then the Blynk is not working. How can I make both of them working and then I can read the gps data from GPS Shield to the Blynk App.?
This is the code… Whats wrong with this code?
