pretty cool!
Here are some Arduino sketches I have been working on:
1. ping and servo with if clause
#include <Servo.h>
Servo myServo; // Create Servo object to control the servo
int mspeed = 1500;
const int pingPin = 7;
void setup() {
myServo.attach(9);
Serial.begin(9600);
}
void loop(){
Serial.println(readSensor());
if(readSensor() < 20)
moveMotor(readSensor());
//Serial.print ("close =");
delay(200);
//else if(readSensor() > 1) num = 3;
if (readSensor() > 150)
//Serial.println(readSensor());
myServo.writeMicroseconds(1500);
//Serial.print ("far =");
delay(200);
}
long readSensor(){
long duration, inches, cm;
pinMode(pingPin, OUTPUT);
digitalWrite(pingPin, LOW);
delayMicroseconds(2);
digitalWrite(pingPin, HIGH);
delayMicroseconds(5);
digitalWrite(pingPin, LOW);
pinMode(pingPin, INPUT);
duration = pulseIn(pingPin, HIGH);
inches = microsecondsToInches(duration);
cm = microsecondsToCentimeters(duration);
// Serial.print(inches);
// Serial.print("in, ");
Serial.print("SensorVal = ");
Serial.println(cm);
// Serial.println();
return cm;
delay(20);
}
void moveMotor(long SensorVal){
long MotorVal=map(SensorVal, 0, 32, 1700, 1500);
Serial.print("MotorVal = ");
Serial.println(MotorVal);
myServo.writeMicroseconds(MotorVal);
delay(20); //time for the servo to move
}
long microsecondsToInches(long microseconds){
return microseconds / 74 / 2;
}
long microsecondsToCentimeters(long microseconds){
return microseconds / 29 / 2;
}
2. ping sensor with continuous rotation servo
#include <Servo.h>
Servo rmotor;
int num;
int mspeed = 1500;
const int pingPin = 7;
void setup() {
rmotor.attach(10);
Serial.begin(9600);
}
void loop(){
// Serial.println();
// Serial.println(readSensor());
if(readSensor() < 20)
moveMotor(readSensor());
Serial.print ("close");
//else if(readSensor() > 1) num = 3;
if (readSensor() > 150)
rmotor.writeMicroseconds(1500);
Serial.print ("far");
//writeLED();
//break;
//case 3://PR is far
//Serial.print ("far");
//rmotor.writeMicroseconds(1500);
//digitalWrite(LEDpin, LOW);
delay(100);
}
long readSensor(){
long duration, inches, cm;
pinMode(pingPin, OUTPUT);
digitalWrite(pingPin, LOW);
delayMicroseconds(2);
digitalWrite(pingPin, HIGH);
delayMicroseconds(5);
digitalWrite(pingPin, LOW);
pinMode(pingPin, INPUT);
duration = pulseIn(pingPin, HIGH);
inches = microsecondsToInches(duration);
cm = microsecondsToCentimeters(duration);
// Serial.print(inches);
// Serial.print("in, ");
Serial.println (" SensorVal = ");
Serial.print(cm);
// Serial.println();
return cm;
delay(100);
}
void moveMotor(long SensorVal){
long MotorVal=map(SensorVal, 0, 329, 1600, 1500);
Serial.println (" MotorVal = ");
Serial.print(MotorVal);
rmotor.writeMicroseconds(MotorVal);
delay(100); //time for the servo to move
}
long microsecondsToInches(long microseconds){
return microseconds / 74 / 2;
}
long microsecondsToCentimeters(long microseconds){
return microseconds / 29 / 2;
}
3.my knock
/* Knock Sensor
This sketch reads a piezo element to detect a knocking sound.
It reads an analog pin and compares the result to a set threshold.
If the result is greater than the threshold, it writes
"knock" to the serial port, and toggles the LED on pin 13.
The circuit:
* + connection of the piezo attached to analog in 0
* - connection of the piezo attached to ground
* 1-megohm resistor attached from analog in 0 to ground

// these constants won't change:
const int ledPin = 13; // led connected to digital pin 13
const int knockSensor = A0; // the piezo is connected to analog pin 0
const int threshold = 5; // threshold value to decide when the detected sound is a knock or not
// these variables will change:
int sensorReading = 0; // variable to store the value read from the sensor pin
int ledState = LOW; // variable used to store the last LED status, to toggle the light
void setup() {
pinMode(ledPin, OUTPUT); // declare the ledPin as as OUTPUT
Serial.begin(9600); // use the serial port
}
void loop() {
// read the sensor and store it in the variable sensorReading:
sensorReading = analogRead(knockSensor);
// if the sensor reading is greater than the threshold:
if (sensorReading >= threshold) {
// toggle the status of the ledPin:
ledState = !ledState;
// update the LED pin itself:
digitalWrite(ledPin, ledState);
// send the string "Knock!" back to the computer, followed by newline
Serial.println(sensorReading);
}
delay(50); // delay to avoid overloading the serial port buffer
}
