10. Output devices

This week assignment

group assignment: - Measure the power consumpion of an output device. - Document your work on the group work page and reflect on yourt individual page what you learn, individual assignment. - Add an output device to a microcontroler board that you´ve designed and program it to do something

Research

This weel assignment is about adding some output device to a citrcut that i designed,i did go thrugh some solid state relays, i will most likely use some solid state relays in my final project that wil turn on some led and sound, i didi find two SSR-40DA relays in my work they ar 3-32VDC on the input and have 24-380VAC on the Output i think this relay will fit good in this week assignment, but in the final projegt i will maybe use some other relay that depends on the actual power/voltage need of the components that i will use in the end.

Assignment

In this week i am goin to use the circut board i used in week 09 and add a output for tu solid state relays to it. I will make it to work like that:
1. Motion senser wil give signal to the RP2040
2. Then i will have two 230V lightballs connected to two solid state relays. 3. when first movment is registerd , light one will com on. 4. When second movement is registerd, light 2 will also come on.
5. When thirde movment is registerd both lights wil blink to geather 5 times.
6. When they have blink 5 times the motion sensor counter will reset to zero and the loop will start again.

Code used

I did use code that i had for sensor to turn on one light and change it to turn on one light and have anothor light turnd of if no motinon and if detected motion it eill turn off the light that was on and turn on the light that was offi slso let the program add message on the computer screen that says if motion is detected or not using serial.println command

int sensorPin = 26; // PIR sensor output pin
int ledPin = 27;   // LED pin
int ledpin2 = 28; // LED2 pin
void setup() {
pinMode(ledPin, OUTPUT);
pinMode(ledpin2, OUTPUT);
pinMode(sensorPin, INPUT);
Serial.begin(9600);
}
void loop() {
int sensorState = digitalRead(sensorPin);
if (sensorState == HIGH) {
digitalWrite(ledPin, HIGH); // Turn LED on
digitalWrite(ledpin2, LOW); //turn led2 off
Serial.println("Motion detected!"); // tell if motion is detected
} else {
digitalWrite(ledPin, LOW); // turn led off
digitalWrite(ledpin2, HIGH); // Turn LED2 on
Serial.println("No motion detected!"); // tells if no motin is detected
}
delay(100);
}

## process I started by finding the material and make the code then i tested this all on breadbord before doing anything else.

Then i did make the circut in Kicad, milled it out, solder and tested

Code i used for OLED 1306 display

void setup() {
   Serial.begin(9600);

  // SSD1306_SWITCHCAPVCC = generate display voltage from 3.3V internally
  if(!display.begin(SSD1306_SWITCHCAPVCC, SCREEN_ADDRESS)) {
    Serial.println(F("SSD1306 allocation failed"));
    for(;;); // Don't proceed, loop forever

}
}
void loop() {
  display.clearDisplay();             // Clears display buffer
  display.setTextSize(2);             
  display.setTextColor(SSD1306_WHITE);       
  display.setCursor(0,0);             // Start printing at top-left corner
  display.println(F("Hello ANDRI here is my OLED 1306 display working!")); 
  display.display();                  //displays the text on screen
}
