Code Arduino mpe vidéo ya capteur ya tilt

Projet oyo emonaki ndenge ya kosala senseur ya kotengama (tilt sensor) na Arduino. Senseur oyo ekoki kosalelama na bisika ebele epai koyeba mbongwana ya etindo ya eloko ezali motuya mingi. Tala makanisi mosusu awa:

• Robotiki: Kota senseur ya kotengama na loboko ya robot mpo na koyeba esika mpe etindo na yango.
• Sistemi ya libateli: Salela yango lokola commutateur ya kotengama mpo na alarme ya libateli, mpo na kopesa elembo soki eloko etengami.
• Kotalela ya Industrie: Kotalela kotengama ya masini to biloko mpo na koyeba mikakatano to kozanga libateli.
• Ba Controleur ya Masano: Kota yango na controleur ya masano mpo na ba entrée oyo etali kotengama.

Projet oyo esalelaka module ya senseur ya kotengama, microcontrôleur Arduino, mpe ba composants moke mpo na kosala sistemi ya koyeba kotengama. Senseur yango ebimisaka signal ya se (LOW) soki etengami, oyo Arduino esosolaka mpo na kopelisa LED mpe buzzer (na vidéo na 00:18).

Matériel/Ba Composants

Matériel oyo esengeli mpo na projet oyo ezali: (na vidéo na 00:49)

• Arduino Uno (to oyo ekokani na yango)
• Module ya Senseur ya Kotengama
• Buzzer
• LED
• Résistance ya 220Ω (mpo na LED)
• Ba Fils ya Jumper

Mokambi ya Kotia Ba Fils

Kotia ba fils ezali pete. Tala vidéo mpo na mokambi ya kotala. (na vidéo na 02:36) Ba connexions ya minene ezali:

• Senseur ya Kotengama VCC na Arduino 5V
• Senseur ya Kotengama GND na Arduino GND
• Senseur ya Kotengama DO na pin 2 ya Arduino
• Lokolo ya LED ya + na pin 8 ya Arduino na nzela ya résistance ya 220Ω
• Lokolo ya LED ya - na GND ya Arduino
• Lokolo ya Buzzer ya + na pin 8 ya Arduino
• Lokolo ya Buzzer ya - na GND ya Arduino

Bokambi ya Code

Code ya Arduino esalemi mpo na kotanga mbimbi ya senseur ya kotengama mpe kokamba LED mpe buzzer na ndenge oyo esengeli. (na vidéo na 04:30)

#define TILT 2 // pin 2 mpo na senseur ya kotengama
#define LED 8 // pin 8 mpo na LED mpe buzzer

Ba constantes TILT mpe LED balobaka ba pins ya Arduino oyo esangani na senseur ya kotengama mpe ba composants ya kobimisa, na ndenge ya kolandana. Okoki kobongola ba numéro ya ba pins oyo mpo na kokokana na kotia ba fils na yo. Logique ya ntina ezali na fonction loop(): (na vidéo na 05:36)

int TILT_SENSED = digitalRead(TILT);
if(TILT_SENSED == LOW) {
  digitalWrite(LED, HIGH);
  Serial.println("Tilt detected");
} else {
  digitalWrite(LED, LOW);
  Serial.println("Normal");
}

Code yango etangaka état ya senseur ya kotengama na kosalela digitalRead(). Soki senseur etengami (LOW), LED mpe buzzer bapelisamaka (HIGH); soki te, bafungwamaka (LOW).

Fonction delay(200); (na vidéo na 07:16) ekambaka mbala ya kotanga ya senseur. Bongola valeur oyo mpo na kobongola mbala ya kotalela senseur.

Projet/Démonstration ya Miso

Vidéo yango emonaka ndenge senseur ya kotengama esalaka. (na vidéo na 07:34) Soki esaleli etengami na etindo oyo eponami, LED epelaka, mpe buzzer elobaka, kolakisa ete kotengama emonami. Sensibilité ya senseur ekoki kobongolama na potentiomètre (na vidéo na 07:50), mpo na koyokisa yango na ndenge oyo esengeli.

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.
