2° Passo

Nova atualização V 1.1

Nessa atualização do software do Arduíno incluímos uma escala de porcentagem em numero e barras e mudamos a forma de reação do LED pois na versão 1.0 o LED ficava mais forte com a intensidade da luz ambiente bem clara o que deveria ser ao contrario, nessa versão V 1.1 arrumamos isso.

Código comentado

Essa nova atribuição no software mudou a forma de manipular o LED agora quanto menor a intensidade de luz do ambiente maior o LED vai clarear, isso por conta de uma simples mudança na função MAP:

- LED vai clarear com mais luz ambiente

  outputLed = map(sensorValue, 0, 1023, 0, 255);    

- LED vai clarear com menos luz ambiente

  outputLed = map(sensorValue, 0, 1023, 255, 0);  

Todo o código na função Loop  entre o  " switch (programas){"  e o  " break;} "   é para criar no LCD uma barra visual de porcentagem.

Vídeo 

Reparem a escala numérica e em barras da porcentagem e o led variando a intensidade apartir do PWM.

Ola galera, segue abaixo alguns videos pra vocês poderem acompanhar como anda o projeto.

Datasheet LDR

Ola galera.

No post de hoje trago o datasheet do sensor de luz que estamos utilizando, o LDR, lembrando que o motivo da sua escolha foi o seu custo beneficio que é excelente, e ao fato de apresentar uma sensibilidade semelhante ao espectro visível, sendo assim o mais indicado para o controle de intensidade de iluminação.

1° Passo

Ola galera.

Resolvemos fazer um passo a passo do nosso projeto para ficar fácil de todos entenderem, pois bem esse vai ser o nosso primeiro passo a passo e hoje o foco sera a parte física do projeto onde sera apresentado todo o embasamento pratico do circuito sem entrar em muito detalhes teóricos a grande parte teórica ficara para nosso segundo tutorial.

Nosso projeto até o momento constitui de realizar testes de aquisição e manipulação de dados, já que o projeto final tem como finalidade controlar a intensidade luminosa de um ambiente através de uma lampada sendo regulada através de um processo automático que sera realizado pelo nosso Arduíno através da aquisição de dados de um sensor LDR.

Lista de material

- Arduino UNO

- Sensor de luminosidade LDR

 - Protoboard para realizar os teste

- Resistores para começar a regular a sensibilidade do LDR

- Led para teste 

- Alguns fios para ligação no proto

Segue fotos da montagem pratica:

Segue o programa v 1.0:

#include <LiquidCrystal.h>

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

int sensorPin = A0;    

int sensorValue = 0; 

int outputValue = 0;  

int led = 9; 

void setup() {

  lcd.begin(16, 2);

  pinMode(led, OUTPUT);

}

void loop() {

  lcd.setCursor(0, 0);

  lcd.print("LDR");

  sensorValue = analogRead(sensorPin);   

  outputValue = map(sensorValue, 0, 350, 0, 100);    

  lcd.setCursor(6, 0);

  lcd.print(sensorValue);

  lcd.setCursor(0, 1);

  lcd.print(outputValue);

  analogWrite(led, sensorValue);

  delay(100);

  lcd.clear();

} 

Código comentado:

Nesse ponto adicionamos a biblioteca do LCD e atribuímos os pinos de comunicação

 * LCD RS pino 12

 * LCD pino 11

 * LCD D4 pino 5

 * LCD D5 pino 4

 * LCD D6 pino 3

 * LCD D7 pino 2

 * LCD R/W pino GND

#include <LiquidCrystal.h>

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

Adicionamos o pino A0 como entrada do nosso LDR e o pino 9 como saída de PWM para nosso LED e suas variáveis para manipulação de dados.

int sensorPin = A0;    

int sensorValue = 0; 

int outputValue = 0;  

int led = 9; 

Pegamos o sinal de entrada pela porta analógica A0 e salvamos na variavel " sensorValue"

  sensorValue = analogRead(sensorPin);   

Construímos um "map" entre os valores de 0 a 350 de entrada ele fara uma regra de 3 e processara em dados de 0 a 100 e vai imprimir no LCD.

  outputValue = map(sensorValue, 0, 350, 0, 100);    

  lcd.setCursor(6, 0);

  lcd.print(sensorValue);

Com os dados em sensorValue iremos controlar a intensidade do LED através de PWM

  analogWrite(led, sensorValue);

  delay(100);

Segue as fotos do nosso circuito:

OBS: Esse é o nosso primeiro teste vários fatores serão melhorados, no próximo passo a passo iremos regular a sensibilidade e fazer a mostragem dos dados em escala de porcentagem.
