Schema and PINs Question
Closed this issue · 10 comments
Hi, cool project :-)
Bought the IRF520. Now I am after the 4-channel Logic Level Converter - Bi-Directional but I am having trouble to find what it is and does. I can't find a model on amazon.de, can you help me out from there? Following the diagram I have a hard time to find a "replacement" board and match the pins on that. Also the wemos misses pin numbers, is that the default?
Should this be the one?

How would the pins match your schema?
Thanks in advance!

Yes, Wemos has default PINs. Unfortunately export from Fritzing app cut it off. Will try to fix.
UPDATE: Upload PNG schema. PIN names is in its place.
Hi, thanks. I am now trying... but no success yet. BTW I use an esp32, but it is not even powering up. why is both the 3.3v and the 5v connected to the esp?
When I put 12V on the IRF520 I only get 1.3V to go to the esp on VCC and GND?
You need to provide low and high voltage for Bi-Directional convertor by connect 3.3v and 5v to converter.
An IRF520 has a threshold voltage in the range of 2 to 4 volts, so ESP32 has 3.3v which enough to turn on.
PS : there is no power supply of ESP8266 on the diagram, but its presence is implied.

Sorry, do you mean the "12V" part is not the supply for the esp and thus that needs to be powered separately? And if so, do you mean that if I connect 5V to the ESP it will output 3.3 and them both will power the bi-directional converter... etc.? Please help out :-)
Edit:
I have supplied usb power... but since I use an esp32 I changed
I have a very slow spinning fan on boot and can control via homeassitsant... but I cannot get it to spin hard... tried also:
output:
- platform: gpio
pin: GPIO18
id: fan_supply - platform: ledc
pin: GPIO23
frequency: 10000 Hz (also tried with 250000 Hz)
id: pwmfan
Here I play with home assistant slider:
[D][main:262]: Power of Fan turned OFF�
[D][speed.fan:035]: Setting speed: 0.00�
[D][main:255]: Power of Fan turned ON�
[D][speed.fan:035]: Setting speed: 0.27�
[D][main:268]: Write 100% to output pwmfan�
[D][pulse_counter:159]: 'esp32-05 Fan Speed': Retrieved counter: 0.00 pulses/min�
[D][sensor:131]: 'esp32-05 Fan Speed': Sending state 0.00000 RPM with 2 decimals of accuracy�
[D][speed.fan:035]: Setting speed: 0.66�
[D][speed.fan:035]: Setting speed: 0.07�
But no hard spinning...
Any tips?
Yes - ESP needs to be powered separately.
Seems your Bi-Directional convertor is not working correctly. You should check the voltage on Bi-Directional convertor on 3.3v and 5v. Both voltages must be present on the convertor. Not all types of ESP boards provide 5v voltage output on PIN.
Ok, some more info. I have 12.14 v in. 3.3v on the 3v pin. 4.65v on the 5v pin.
Upon start of the set I get a rating fan but no logging.

Setting the speed above .25 stops the fan...

how did you get that slider for speedcontrol
Quick question to the Author - in your diagram it was very clear, however, there is one thing that i found out of place:
The way that the standard 4 wire PINout (Pins 4,3,2,1) is (SpeedCommand, Feedback, 12v, Ground), however,
In your diagram, your Green Wire (which is clearly your pulse counter), is mech'd to PIN4 of the 4 wire fan. (and your yellow wire, which is the Command line to D7) is Mech'd to PIN3.
Everything in your description is so purposefully aligned with the standard, I'm curious why you flipped the wires? Or is there some nuance I'm missing?
Thanks a bunch -- I am also seeing some low speed fan behavior using a D1 mini - similar to observations described by the other commenter above, but I thought I'd make sure I get all the base assumptions aligned first.
Thank you!

My mistake - mismatch pins with diagram. Fixed in code. Thank you!
