OK, that's very simple indeed. https://i0.wp.com/miliohm.com/wp-content/uploads/2019/09/schematic.png You simply add some pull-up resistor between 3V3 and the "coin" pin. The "coin" pin should then be connected to a GPIO pin on the ESP. Please consult these tables to pick the ri...

What voltage is there at the "coin" pin? Or is it a mechanical switch and if so, will it connect to GND or +12V? Sorry I am not familiar with that mechanism but can you look at that page "https://miliohm.com/coin-acceptor-or-coin-sensor-tutorial-with-arduino/" and help me. Someb...

Hello to all, I decided to make a coin acceptor relay board with nodemcu with your helps. I have a cheap chinese coin acceptor mechanism. There are Ground, coin and dc+12 pinout at hte coin mechanism. Which pins should I use at the nodemcu? Later I will connect an LCD to the nodemcu.

Thanks ThomasB and TD-er both of you. I will do what you describe.

Hello all,
I need to combine 3-4 (maybe 2) motion sensors (hc-sr501)to the same input of the esp easy. I read something about or gate ic component, is there anybody advice me which or gate ic should i choose?

Then you can send commands via HTTP on 192.168.4.1 (the IP of the node running with AP enabled)

Thank you

Thanks for your effort, what are my alternatives to use instead of ESP_NOW between two nodemcu without access point?

Hello,
I want to communicate between two nodemcu modul without access point. What should I use? Actually I read about ESP-NOW but cannot find anything how to install ESP-NOW to the nodemcu? Which firmware version should I use?

You can change the names of Button1 and Relay1 to whatever you named your tasks.

Hi to all,
I have a relay that connected to GPIO-12 name is relay and an input switch (push-button) that connected to the GPIO-13 and name is switch. When I press the button, if the relay is closed, I want it turned on, and if it's on, I want it turned off. What should my rule be like?

- Define a Dummy Device (on Task: 5 name=Reboot, variable: 1 name=Last, in my case) - Change your code like this: On Clock#Time=All,12:00 Do If [Reboot#Last]<>%sysday% TaskValueSet,5,1,%sysday% // Will survive a reboot, not a power-cycle Reboot EndIf EndOn NB: Untested!

I want to restart my nodemcu once a day. So i put a script like that.

It is a rather extensive new feature, so I'm already working on it for a while so don't expect it this year.
Hopefully at the beginning of next year.

That would be a magnificent feature.

so how can i transform that value to the hex data to send it with my nodemcu's ir transmitter? ESPeasy has a string transform function (strtol).

On the sender side you also need to have the ESPEasy p2p controller and link it to the task you want to send via p2p. On the receiver end you need to have the task nr empty which you try to send.

Yes, use ESPEasy p2p for that. See: https://espeasy.readthedocs.io/en/latest/Controller/C013.html#c013-page Just make sure to have unique unit nrs (not 0, not 255) and use the same UDP port (8266 of course) among them in the same network.

GPIO boot states are only acting on the internal GPIO's. If you need to set pins on the external GPIO's, then I would suggest to use rules. Thank you, it works very well.

I notice that P0 to P7 ports of the PCF8574 GPIO extender is always on after reboot of the nodemcu. How can i set the P0 to P7 ports always off after reboot, should i make a rule or set something at the GPIO boot states ?

How can i do that?

2. No ! The led of the optocupler needs ~1.15V / 10mA. You can not remove the resistor. And the PCF8574 cannot drive +10mA. 3. Look at the IR-led datasheet. If it only needs 300µA, would be unusual, it could work ! In my opinion, there is no Led that works with 300µA. You need a additional transist...

asuz

You can't connect the LED-anode to the output of the PCF8574, because it need more than 300 μA ! Better connect the anode of the LED (or LED oft the optocupler) to 3.3v, cathode to the ouput and switch with a low-output. Sorry, i am working that project for a while and my mind mixed, do not underst...

Have you tested using a LED and 220 Ohm resistor to check if the PCF does allow to draw the needed current for the LED? Do you know the voltage drop of the LEDs in the optocoupler?

Understood. My electricity knowledge is not that great but basically your KVM will provide +5V and little switches need to be grounded to operate. You do want to command them remotely with a remote (existing or that doesn't matter ?). The IR led is for what though ? You have to pilot something else...

You mentionned in your previous post a possible boot problem if you use 6 GPIOs of the Lolin. Is that the case or was it just precaution ?

Ath wrote: ↑22 Oct 2020, 22:18 It looks like the default I2C addresses for both PCF8574 and LCD2004 are 0x20, so you should change one of them, and as the PCF has jumpers you could move the A0 jumper to the other position, so it should be configured for 0x21 instead.

Thank you, i will try.

asuz

Well I think it isn't a bad idea here to use optocouplers to replace or override the switches. After all you don't know if the switches are connected to GND or Vcc and changing impedance may affect the operation of the KVM switch. You are right switches are connected to GND not Vcc so I realize tha...

If you replace the current LEDs on the unit with the LEDs of the optocoupler, you don't need extra resistors. N.B. the same applies when you set the optocoupler LEDs parallel. There is however a big BUT here... Can you measure the voltage drop over the LED in the optocoupler? If this is a higher vo...
