i tried installing it, it downloaded but didnt install socat and now im retrying and it says => Homebrew has enabled anonymous aggregate user behaviour analytics.
It for some reason keeps saying permission denied
-bash: ./blynk-ser.sh: Permission denied
Daniils-Macbook:scripts daniilkharlashko$
Iām not a MAC user but I know it has sudo like Unix for root access and using the USB port can require elevated privileges.
If you are SURE homebrew is installed try the script call command prefixed with sudo.
It still hasnt fixed it any other suggestions i am glad and thankful that you are helping me
OMFG i fixed it i found the way i searched other problems that people had i found the same one and it said place sh ./blynk-ser.sh THank you man i am happy now but i will have to now figure out how to use my PIR sensor and use it to send email to my email
Maybe, if you go back and edit the code to include backticks for forum posting. Google it if it doesnāt mean anything to you.

Looks like you have 3 setup() and 3 loop().
Post again.
i am not good at coding if you can help me fix the mistake its would be great i will fix them now

This is the first sketch you should run if you are using a USB connection. Look through the sketch including the important notes about the V5 widget and adding your token etc. Do you have a USB2TTL adaptor for Serial Monitor debugging as per the SoftwareSerial entries?
If you donāt you might have to work blind without any debugging options. Let us know if V5 updates in your project with uptime in millis().
/*************************************************************

This example shows how value can be pushed from Arduino to
the Blynk App.
NOTE:
BlynkTimer provides SimpleTimer functionality:

i dont have an adapters, so what do i do now do i use this code ? and combine it with my previous one?
Just muddle through without one for now.
Donāt combine yet. The first step is always to get a basic Blynk sketch running for your particular connection method. No point trying to land on Mars before we have built the rocket.
Run the sketch I posted and report back.
I have placed eveything in the code correctly and the app but it does not output the values, do i have to repeat all the same steps using terminal?
Sequence,
Build the project in the app (V5 and get token).
Flash the sketch to Arduino with token.
Run USB connection as you were doing earlier on and leave it running.
i did this but i am not getting any displayed information on my blynk phone app
what do you exactly mean by, flashing? i have copied the code edited it pasting the auth and then uploaded it.
Yes this is flashing.
Does MAC terminal suggest you are connected to the Blynk server?
Difficult to debug without Serial Monitor access from a USB2TTL adaptor.
