Hi Sara ! when I initially add the app for the site to firebaseConfig, I don’t see databaseURL: “”, and I did all the same steps as you. is this a problem or can I continue my project without this aspect?

Both the rules and code are unchanged from the ‘ESP32-CAM Save Picture in Firebase Storage’ tutorial.
Thanks

Hi,
How do you make the ESP32 Cam display video to firebase?

Hi.
What are your database rules?
How are you setting the anonymous user in the code?

Hi Sara,

As you suggested, the fault was in the ‘Firebase Arduino Library for ESP8266 and ESP32’ version 4.3.7

The latest version, just out, 4.3.8 seems to work fine and does not give the ‘File not found’ error.

Hi Random Nerd Tutorials,

I need some help and was wondering if you could provide some support?
I need to power the following projects/components directly via my motorcycle’s 12V Battery (the same battery would be powering all the bike’s electricals)

Reverse camera + GPS (Fitted at back of bike, rear facing)
Parts used:

– ESP 32 Cam module
– NEO 6M GPS Module
Application:
To keep an eye on vehicles coming from the rear end

Proximity sensor (Fitted at back of bike, rear facing)
Parts used:

– Arduino Nano
– HC SR04 sensor
– Buzzer
– Red LED
Application:
To detect vehicles coming from the rear end and activate the buzzer and led if vehicle comes in a certain range of distance

Placement of both projects:
On a motorcycle, directly attached with the battery terminals (Same battery will be used to power other motorcycle electronics)

Question:
1. What is the safest way to hook up the circuit with the bike’s battery? As you may know, the bike battery offers fluctuating voltage (9-15.5V, even lower during cold cranking) and there may also be voltage surges/transients upto 100V.
2. What is the best way to power up the ESP32 cam module – Arduino Nano or other source?

Motive: I want to provide a safe, stable, clean power source to my circuits.

Any help would be appreciated. Thanks in advance.

In reply to Clayton. Update: Got the web app up but now I am getting “Uploading Photo…Permission denied.” My storage rules are correct I’m not sure on what to do next. Thanks
