Croduino stepper motor frequency measurement with LCD or LED display

Customer:

I purchased a stepper motor and driver module from the ULN2003 stepper motor guide. Since this area of electronics is new to me, I’m interested in how I can measure the stepper motor frequency and display it on an LCD screen using a Croduino board.

Since stepper motor frequency is square wave, an alternative to LCD display would be using an LED that lights up when the stepper is running and turns off otherwise.

naručio sam stepper motor i modul s linka Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics .

S obzirom da mi je ovo područje elektronike nepoznato, zanima me kako mogu dobiti mjerač frekvencije stepper motora s prikazom iste na lcd zaslonu koristeći croduino pločicu?

Pošto je frekvencija stepper motora kvadratna, umjesto prikaza na lcd zaslonu, alternativa bi bila korištenje led diode koja bi svijetlila kad je pokrenut stepper i obratno.

Svaka je pomoć dobrodošla!

Soldered Support:

Since you’re using the ULN2003 driver which contains only four transistors and the code directly controls these transistors, you can add lines of code in the sections where you turn on specific transistors to also light up your LEDs to signal the control signal.

LCD display would also be possible with some additional programming.

budući da koristite ULN2003 driver koji su samo četiri tranzistora, a programski kod također upravlja direktno tranzistorima. Možete samo u dijelove koda gdje palite određene tranzistore dodati linije koda koje pale Vaše LEDice te tako signaliziraju signal.

Na LCDu bi se također moglo s malo dodatnog programiranja.
