Re: How to switch on a electric bulb with ESP8266 board?

You can control that by the initial value of i 0 or 1. If you want the behaviour to change in certain times, you need to know the real time. But you were at that question before. Hi Robert, yes, i am aware of real time which we need to synchronize with ntptime and for this we need internet. But, i ...

Code: Select all

    if level >= 10:
       i = 0
    time.sleep(1)
Thank you Robert. Now logic is working fine.

Re: How to switch on a electric bulb with ESP8266 board?

There are many ways to do it, depending on the electronic interface of the device. MicroPython supports various interfaces: UARTs, I2C, SPI, CAN or simply changing Pin inputs. There are also drivers for various devices, some official, some contributed by users. UARTs are somewhat problematic on ESP...

Hi pythoncoder, below screenshot may give an idea what i am trying to say. is it possible to pass a value from external device at runtime to ESP8266 ?

Re: How to switch on a electric bulb with ESP8266 board?

@RajaRamesh The ntptime module is merely used to initialise the RTC. If you have an internet connection it's the obvious way to do it, but you can set it by any means you wish. Note that the RTC on the ESP8266 is not very accurate and it may need setting at regular intervals. Ok...pythoncoder. is i...
