It keeps saying timeout


Sketch uses 12570 bytes (4%) of program storage space. Maximum is 253952 bytes.
Global variables use 494 bytes (6%) of dynamic memory, leaving 7698 bytes for local variables. Maximum is 8192 bytes.

I've already installed CH340 and tried to upload from two computers. I dont know whats wrong..

Using HC-05, Arduino Mega 2560, and 7 LEDs with 2 Buzzers. Trying to make an auto medicine-taking reminder using the Blynk IOT app as virtual widgets to set the specific time reminders. LED and Buzzer will sound off upon the time set. One time widget is for one LED. A total of 7 associations. Please help ...

Something on pins 0 and 1, like HC-05? Disconnect it before upload.
BTW, sketch has nothing with a upload error if it fits into memory.

4

Do I just unplug the HC-05 before upload?

5

Yes.

6

Thank you so much brotherrr

7

Do I just connect the HC-05 back upon uploading to pair it with the Blynk IOT app?

8

The upload process uses Tx,Rx it means pins 0,1. You cannot use them for anything else until the upload is complete. Discomfort? Sure. However Mega 2560 has another 3 HW serial lines. Consider to use one of them.

9

Are you referring to the 3HW serial lines to the other 3 sets of TX and RX communication pins?
So using TX314 and RX315 won't affect the upload? Must i change my code since the connections are different now?
