ok. in your post you write Serial Monitor, but you mean Serial interface. Serial Monitor is a window in IDE.

your code for reading the data looses the characters. read about Serial input basics

If you edit your Original Post you can change the title to describe what you want help with - perhaps "How to create PCB test fixture"

I meant this was the selection throughout!
Not if it actually said:

Code: [Select]
Expected signature for ATMEGA328P is 1E 95 0F Double check chip, or use -F to override this check.

I tried another stepper as well but the same problem..
Changing the motor should not make any difference.

Try a different stepper driver - my guess is that the one you have been trying has a fault.

Programming Questions / Light chaser with 74hc595 and ...
Last post by w31x - Today at 11:03 am
I would like to make a light chaser with the 74hc595 and let it run in a kind of wave. The first led is faded and getting brighter and brighter.
The whole thing should be realized with a shift register, because I want to drive many leds so.
I have found this program (including video) for Arduinocontroller like the Uno here ->

It is about synchronizing the interrupts of the timer with the frequency of the ESP. However, I am not so deep in the programming that I could realize this alone for the ESP8266, so I hope here in the forum are a few people who can help me with this program.

Sry dann habe ich mich geirrt.
Macht ja nichts, wir lernen alle dazu. ;)
I imagine it would be possible to get a servo that would be capable of operating the steered wheels. Very powerful servos are available, if needed.

A servo will be the easiest option mechanically, electrically and program-wise.

An alternative. And probably  cheaper.
