Re: Problems with push button , self activation

Ok drilling the cabel did not really help. So i inserted a 1k ohm resistor between 3.3V and my pin. But this also did not work. Now it seems that my ESP is damaged. It works at long as it is cold. After plugin it in it gets warm. When resetting when warm it does not work anymore. No Wlan, no flashin...

Re: Problems with push button , self activation

Ok,

i drilled the cables. This already did the Job.
Crazy.

Thank you for your help!

Re: Problems with push button , self activation

Ok, now i understand.
Thank you very much for the detailed explanation!

I will try to get it working with all your hints how to do it.

Thanks,

Re: Problems with push button , self activation

Thanks a lot for the help. I will try the different options. Twisting the wires is a good idea. Also using an external pull up resistor sounds good and i understand why. What i do not understand, what is a capacitor doing? ("Connect a capacitor of about 47nf...100nF from GPIO to ground") Thanks and ...

Re: Problems with push button , self activation

Ok, thanks Thomas. From the place where i want to install the switch i have to use 30cm wire :-( I will try with another power supply and with the 1K ohm PullUp resistor. One question to the 1k PullUp resistor. Isn't this exactly the same as "Internal PullUp Checked (Enabled)"? Thanks and best regar...

Problems with push button , self activation

Hi, i have a problem with the switch plugin. Connecting a push button works, but i get strange self triggerings. To get a unwanted event it is enough to connect a 20cm wire to the gpio i where the button is configured. When i take the wire in my hand and move it a little bit or rub on it, a event is...

Re: Change PWM Frequency ?

Hi, i wanted to inform you that i got an arctic PC Case Fan now. This is working fine. PWM 0 is really stopping the fan! I think kusing a CPU Fan in the first place was my problem. At least my CPU Fan logic was that it still spins with PWM 0. But with the case Fan everything is working great now. Th...

Re: Change PWM Frequency ?

Yes, i also thought about a Relais.
I need one component more. I was hoping that it will work without a relais.

Lets see if the Fan will stop with pwm 0, if not i need to use a relais.

Thanks and bets regards,
Stefan

Re: Change PWM Frequency ?

Oh ok, i think i see our misunderstanding. I have a pwm controlled 12 V Fan for PC CPU. It has a 4 Pin terminal. Ground 12 V Tach PWM I connect Ground and 12V to the Fan. Also i connect my ESP to the same Ground. I connect PWM to my ESP. Now i can control the fan with the ESP by driving the PWM inpu...

Re: Change PWM Frequency ?

Hi Patou,

yes i measured the pwm output.
3,3V is the voltage of the ESP PWM output at max.

No i do not have a transistor between 12V and pwm.
Why is this necessary?

Bets regards,
Stefan

Re: Change PWM Frequency ?

Hi Patou, thanks for your reply. Do you mean the voltage of pwm terminal? There i have: 0 = 0.02V 1023 = 3.30V I think i understand now. I found a spec describing PWM. PWM Control Input Signal he following requirements are measured at the PWM (control) pin of the fan cable conne WM Frequency: Target...

Re: Change PWM Frequency ?

Hi, i attached a 12 Volt PC fan to my ESP8266. PWM signal line is connected to GPIO2. I tried with the pwm command from above. It is working, but not as i would like. From above the syntax is: PWM,<GPIO>,<duty>,<duration>,<frequency> Setting duration or frequency does not change the fans speed. The ...

Re: US-100 distance sensor support

Hi,

i am also interested in the US100 in serial mode.
It should be very accurate!

Is it possible to integrate it in ESPEasy?

The code for serial mode in Arduino can be found here:

Thanks and best regards,
