Servo don't work

But are they in parallell or not?
The picture does not make it clear.

Do you see my home assistant config ?
(Esphome, yaml and automation config)

Hi
What do you mean to paralell ?
Regards

Yes.
But I have not read it to be honest. You wrote that it’s the example code so I believe you.
Most of the time it’s due to the servo not getting the current it needs that is the problem.
That is why I’m very persistent on the wiring.

The positive end should split in two, one to the VCC of the 8266 and one end should go to the motor positive.
If you are unsure of the wiring then, be sure.

Hi
I use 2 séparate power (one for servo and one for ESP8266) but every ground are on ESP8266

Hi!
Why don’t you give it a try directly on the esp8266. For testing only, connect the ground and the 5v pin on the esp and d4.
In the photo I see the red cable( I suppose it’s the 5v cable) connected to s1 or s2? Does this pin gives 5v??
I am using a d1 mini as I said before, and for testing I connect it directly on the wemos, after testing I used an external power supply because I wanted to control 3 servos. I will send you a photo when I arrive at the office!

good morning, I have a servant that does not work. I am using a nodemcu board, programmed following the instructions on the esphome website. Can you take a look at the photos if I made a mistake in the configuration? thank you all

Hey,
I face almost the same Problem then everyone. I got a Servo ( Amewi Standard-Servo 6221MG) and in the first step I would like to control it with a slider in Home Assistant. I connected the Servo directly to the Board on Pin 5V /GND / PIN D2 but it is not moving when I move the Slider. Maybe someone can help me here.
The Board I used is: ( AZDelivery D1 Mini V3 NodeMCU ESP8266EX from Amazon)

Heres also a Picture of my ESPHome Deviceconfiguration / my configuration.yaml /my automations.yaml and one picture of the Wiring.

Hi
I m not an expert but your servo needs 5v power and D1 output is 3v around

Giloris

Hey giloris,

my D1 has an 5V output pin, I also measured 5V on the output with my multimeter.
I also tried another Wiring with an external wall plug 5V/2A from a smartphone, but it also didn’t work for me.

Hi
Are you sure on fréquency value 330hz ?
Regards
Giloris

Hey I first tried 50 Hz because the seller of the Servo did not specificate it in the description. On the site of the manufacture I found this for my Servo:

Sry its in german but the first value is the working frequency of the Servo.

Are you try power > 5v
Have you noise actually when you move slider ?

I suppose you have testing change signal pin to another one ?

No theres also no noise from the Servo when all is wired and I change the slider. This is also new for me, Im studiying electronics in the 5 semester. :smiley:

Yes, I also tried Pin D3

Theres something strange when I take of the yellow strip for the pwm and I hold it to the PIN or to another GPIO Pin sometimes the Servo moves a little bit.

You tried an external 6v power ?

Hey, no I haven’t. I have a Servotester which also only gives 5 V Output. With the tester the Servo moves.

Here my automation
