Kodi ya Arduino na video ya kihisi cha kuinamia (tilt sensor)

Mradi huu unaonyesha jinsi ya kutengeneza kihisi cha kuinamia (tilt sensor) rahisi kwa kutumia Arduino. Kihisi hiki kinaweza kutumika katika matumizi mbalimbali ambapo kugundua mabadiliko ya mwelekeo ni muhimu. Hapa kuna mawazo kadhaa:

• Roboti: Jumuisha kihisi cha kuinamia kwenye mkono wa roboti ili kugundua nafasi na mwelekeo wake.
• Mifumo ya Usalama: Tumia kama swichi ya kuinamia kwa kengele ya usalama, ikianzisha tahadhari ikiwa kitu kinahamishwa.
• Ufuatiliaji wa Viwandani: Fuatilia kuinamia kwa mashine au vifaa ili kugundua hitilafu au ukosefu wa utulivu.
• Vidhibiti vya Michezo: Jumuisha kwenye kidhibiti cha michezo maalum kwa ajili ya pembejeo zinazotegemea kuinamia.

Mradi huu unatumia moduli ya kihisi cha kuinamia, microcontroller ya Arduino, na vipengele vichache vya msingi kuunda mfumo wa kugundua kuinamia unaofanya kazi. Kihisi hutoa ishara ya chini (low) kinapoinamia, ambayo Arduino huitafsiri kuwasha LED na buzzer (katika video dakika 00:18).

Vifaa/Vipengele

Vifaa vinavyohitajika kwa mradi huu ni pamoja na: (katika video dakika 00:49)

• Arduino Uno (au inayooana)
• Moduli ya Kihisi cha Kuinamia
• Buzzer
• LED
• Kipingamizi cha 220Ω (cha LED)
• Waya za Kurukia (Jumper Wires)

Mwongozo wa Uunganishaji

Uunganishaji ni rahisi. Rejea video kwa mwongozo wa kuona. (katika video dakika 02:36) Uunganishaji muhimu ni:

• Kihisi cha Kuinamia VCC hadi Arduino 5V
• Kihisi cha Kuinamia GND hadi Arduino GND
• Kihisi cha Kuinamia DO hadi pin 2 ya Arduino
• Mguu chanya wa LED hadi pin 8 ya Arduino kupitia kipingamizi cha 220Ω
• Mguu hasi wa LED hadi Arduino GND
• Mguu chanya wa Buzzer hadi pin 8 ya Arduino
• Mguu hasi wa Buzzer hadi Arduino GND

Maelezo ya Msimbo

Msimbo wa Arduino umeundwa kusoma matokeo ya kihisi cha kuinamia na kudhibiti LED na buzzer ipasavyo. (katika video dakika 04:30)

#define TILT 2 // pin 2 kwa kihisi cha kuinamia
#define LED 8 // pin 8 kwa LED na buzzer

Vipengele vya TILT na LED hufafanua pini za Arduino zilizounganishwa kwenye kihisi cha kuinamia na vipengele vya matokeo, mtawalia. Unaweza kubadilisha nambari hizi za pini ili zilingane na uunganishaji wako. Mantiki kuu iko kwenye kazi ya loop(): (katika video dakika 05:36)

int TILT_SENSED = digitalRead(TILT);
if(TILT_SENSED == LOW) {
  digitalWrite(LED, HIGH);
  Serial.println("Ku-inamia kumegunduliwa");
} else {
  digitalWrite(LED, LOW);
  Serial.println("Kawaida");
}

Msimbo unasoma hali ya kihisi cha kuinamia kwa kutumia digitalRead(). Ikiwa kihisi kimeinamia (LOW), LED na buzzer huwashwa (HIGH); vinginevyo, huzimwa (LOW).

Kazi ya delay(200); (katika video dakika 07:16) hudhibiti mzunguko wa usomaji wa kihisi. Badilisha thamani hii ili kubadilisha mara ngapi kihisi kinachunguzwa.

Mradi/Demonstration ya Moja kwa Moja

Video inaonyesha utendaji wa kihisi cha kuinamia. (katika video dakika 07:34) Kifaa kinapoinamishwa katika mwelekeo uliowekwa, LED huwaka na buzzer hulia, ikionyesha kuwa kuinamia kumegunduliwa. Usikivu wa kihisi unaweza kubadilishwa kwa kutumia potentiometer (katika video dakika 07:50), ikikuruhusu kurekebisha kiwango chake cha kuitikia.

/*
What it does?
This module has 3 pins: VCC (connected to 5V), 
GND (connected to GND of Arduino), and
DO (data out), which is connected to pin 2.
From pin 8 of Arduino, when tilt is detected, you can stop a 
motor, move a servo, or turn an LED on to indicate tilt.
