@Dankharl good that the USB connection is working.

Did you enter your token in the sketch that you flashed to the Arduino?

66

what token do you exactly mean?

67

how do i flash the arduino? am i supposed to reupload the sketch to the arduino?

68

The Blynk token that was emailed to you when created the project.

You need to upload the basic sketch we discussed WITH YOUR BLYNK TOKEN INCLUDED.

69

i have already done that, how do i check if it works it doesn’t display anything on the value display on the blynk app.

70

Did you set V5 as PUSH frequency?

Paste your exact Arduino sketch here but replace your token with ABC before you post it here.

From terminal ping blynk-cloud.com and then send me via PM the IP address and your token.

Alternatively you can try this in a browser:

http://blynk-cloud.com/[your-token]/project but replace [your-token] with your actual Blynk token.

71

I have made sure its PUSH

72

it says invalid token

73

Refresh the token in the app, send it to yourself, paste new token in the Arduino sketch and flash it again.

74

I can see why V5 doesn’t show anything and that’s because you are using the wrong sketch.

Look back at what I posted before.

75

should i still do this?>

76

Do i use this sketch?

77

If the USB connection is not dropping then don’t change from SSL to TCP.

78

I don’t see a sketch?

When you said you saw “invalid token” was that in a web browser?

79

yes

80

Do i change the v5 pin to v13?

81

No.

Paste “my sketch” here with V5 and BlynkTimer etc.

82

which one is your sketch? i wanted to ask is there a limited arduino storage so once i use it i have to buy a new one or i can delete all stuff?

This Arduino Email Sending - #34 by Costas

When you flash a new sketch it simply overwrites what is already on the Arduino, it’s not like a hard disk.
