ESP32-CAM Doorbell Low budget version

Needed

• ESP32-CAM AI-Thinker
• 5v 1amp power supply (eg: phone charger)
• 5v Led momentary button (which includes a resistor)
• Universal phone fisheye lens.
• 2 x 1k resistor
• 16v 100mf capacitor
• A way to flash the ESP32-CAM (FTDI adapters are cheap)
• A post image server (LAMP)

Install LAMP server Can be done on multiple ways, I run a RaspberryPi Virtual Machine on a windows server. See tutorial: https://randomnerdtutorials.com/esp32-cam-post-image-photo-server/

A manual install of phpmyadmin might be needed. "http://192.168.x.x/gallery.php" is the location you will find your pictures.
