ESP32-CAM con Arduino (funciona!)
No voy a ocultar que llevo mucho tiempo ausente en esta web, pero los proyectos han seguido adelante.
Hoy comparto un “logro personal”, hacer funcionar de una vez el esp32-CAM despuesd de romperme dias lac abeza probando diferentes códigos por la web (el ejemplo oficial no funcionaba).
