Somo la 107-3: Kudhibiti Motor ya Hatua ya 28BYJ-48 Kwa Kutumia Vitufe Vitatu vya Kushinikiza: CW, CCW, na Simama (STPB-1)
Mradi wa 3: Kudhibiti Motor ya Stepper Kwa Kutumia Kitufe cha Kushinikiza STPB-1 – Motor ya Stepper 28BYJ-48
Makala hii ni sehemu ya mfululizo wa mafunzo ya miradi 8 inayoonyesha jinsi ya kudhibiti motor ya stepper 28BYJ-48 na Arduino. Katika Mradi wa 3, tunatanguliza udhibiti wa kwanza unaotegemea kitufe cha kushinikiza kwa kutumia kitufe cha muda kinachoitwa STPB-1. Kitufe kinatumika kuanzisha mzunguko wa motor kwa kubonyeza mara moja.
Nambari zote za chanzo na mchoro wa wiring wa mradi huu unaweza kupatikana chini ya makala.
📘 Utangulizi
Mradi huu unajenga juu ya yaliyotangulia kwa kujumuisha pembejeo ya kimwili kupitia kitufe cha kushinikiza. Wakati mtumiaji anabonyeza kitufe mara moja, motor inafanya mzunguko mmoja kamili. Mbinu hii ni muhimu katika hali zinazohitaji uanzishaji wa mwongozo wa mchakato wa harakati, kama vile kusogeza jukwaa, kulisha sehemu, au kuendeleza hatua ya kimakanika.
⚙️ Mchoro wa Wiring
Mbali na wiring ya ULN2003 na motor ya stepper kutoka Miradi ya 1 na 2, uunganisho ufuatao mpya umeongezwa:
-
Ncha moja ya kitufe cha kushinikiza (STPB-1) inaunganishwa na pini ya Arduino 2
-
Ncha nyingine inaunganishwa na GND
-
Kipinga cha kuvuta-juu (pull-up resistor) kinasanidiwa ndani ya nambari
Maelezo: Mchoro wa wiring unaoonyesha udhibiti wa motor ULN2003 na pembejeo ya kitufe cha kushinikiza STPB-1 kwa pini 2.
💻 Maelezo ya Nambari
Nambari inatumia pembejeo ya dijitali kugundua kubonyeza kwa kitufe na kuanzisha harakati ya motor:
-
Uanzishaji wa Stepper na Pini:
#include <Stepper.h>
const int stepsPerRevolution = 2048;
Stepper myStepper(stepsPerRevolution, 8, 10, 9, 11);
const int buttonPin = 2;-
Kazi ya Setup:
void setup() {
myStepper.setSpeed(10);
pinMode(buttonPin, INPUT_PULLUP);
Serial.begin(9600);
}-
Inatumia
INPUT_PULLUPkurahisisha wiring (hakuna kipinga cha nje kinachohitajika).
-
Kazi ya Loop:
void loop() {
if (digitalRead(buttonPin) == LOW) {
myStepper.step(stepsPerRevolution);
delay(1000); // Zuia kuchochea mara mbili kwa bahati mbaya
}
}-
Inagundua kubonyeza kwa kitufe (hali ya LOW kutokana na mantiki ya pull-up)
-
Inazungusha motor mzunguko mmoja kamili mbele kwa kila kubonyeza

* Lesson 107-3: Controlling a stepper motor using 3 push buttons.
We have 3 push buttons: one for clockwise (CW), the second for counter-clockwise (CCW), and one for stopping the motor.
In this lesson, we learn how to use a mini stepper motor 28BYJ-48 for our project. I am presenting 8 projects
so you can use it in almost any application. In the video, I have explained the code, shown the full wiring diagram, and
how to connect the wires, push buttons, and breadboard.
Project 1: Running motor
Project 2: Controlling stepper motor from Serial Monitor
Project 3: Controlling stepper motor using push button STPB-1 (this code)
Project 4: Controlling using push button STPB-2 keep pressing
Project 5: One Revolution using push button STPB-3
Project 6: Push button: Any Angle and speed STPB-4
Project 7: Using multiple buttons to control any angle: STPB-5 angle, speed and direction
Project 8: Controlling stepper motor using potentiometer
