Description

ESP8266 Screen Set WiFi Credentials

Transfer data (WiFi credentials) from your smartphone to an ESP8266 by Pulsing your Smartphone Screen

To setup your WiFi Credentials put your ESP12F over a Smartphone screen, and let the Black and White Oscillation transmit the information. Note: You need to cover the LDR, in a way no light can enter. The LDR should not touch the screen, it needs stay some millimeters far from the screen.

Items required:

- ESP-12F (and all the basic componentes to make it work)
- Resistor 300k
- LDR 50K-50M Omhs (GL5539)
- Unzip the library ESP8266-screenSetWifi-master (attached in this projet) into your Arduino Library Folder

PS: You can try other variations of resistor values and LDR types. Just make sure the max resistive value of LDR is greater than the pull-down resistor.

I am implementing exactly the same idea. But you did faster than me. :-)

Very cool! I tried this same thing last year and hadn't succeeded. I started with an LDR setup like yours and had terrible results. Moving to a phototransistor helped but I still never quite managed it. Time to revisit I guess.

Interesting project! How much time does it took to get the information?

  Are you sure? yes | no
