led lcd control
Posted: 23 Nov 2015, 00:00
Hello
I have a esp8266 with a LCD, which is working very well
I noticed that the display lighting LED will connect through the transistor GPIO pin 7 PCF8574
it would be possible to put up an option on the lcd to control the LED blilho
or at least turn on and off?
