Week 7
Weekly tasks
- Measure the power consumption of an output device (e.g. LED, motor)
- Calibrate the sensor (show the conversion relationship between the measured and indicated value in a graph or table).
- Connect an output device that you have not used yet
- Design a program that connects at least one input and one output device
Used tools
Arduino nano, Arduino IDE, ServoThe work
This week I tried to get to know arduino better and connect Servo to it. Servo was chosed mainly because in my final project I want to use it and to know how it works wont hurt. In my final project the Servo would work when touch sensor is activated. But now I didn't have it so I did simple button.
Arduino IDE script
As before I found some examples of scripts for Servo and modified it a bit. In this case also library Servo.h was used (it is in Arduino IDE natively)
#include
Servo myServo; // Create a Servo object
const int buttonPin = 2; // Button connected to pin D2
int lastButtonState = HIGH;
bool servoPosition = false;
void setup() {
myServo.attach(9); // Servo connected to pin D9
pinMode(buttonPin, INPUT_PULLUP);
myServo.write(0); // Start at 0 degrees
}
void loop() {
int buttonState = digitalRead(buttonPin);
if (buttonState == LOW && lastButtonState == HIGH) { // Button pressed
servoPosition = !servoPosition; // Toggle position
myServo.write(servoPosition ? 180 : 0); // Move servo
delay(300); // Debounce delay
}
lastButtonState = buttonState; // Update last button state
}
Final result
