if (digitalRead(switchPin)) { displayDigit(inch); } else { displayDigit(cm); } until you reach the next if statement if (inch<=alarmRange) {startAlarm();} which simply checks if the current measurement from the sensor is smaller or equal to the value in alarmRange that has been set by the user and if so, calls the startAlarm() function. The displayDigit() function is the same as in Project 39: void displayDigit(float value) { int number = value*100; lc.setDigit(0,4,number/10000,false); // 100s digit lc.setDigit(0,3,(number%10000)/1000,false); // 10s digit lc.setDigit(0,2,(number%1000)/100,true); // first digit lc.setDigit(0,1,(number%100)/10,false); // 10th digit lc.setDigit(0,0,number%10,false); // 100th digit } Next is the first of the two new functions. This one is designed to read the potentiometer and convert its value into inches to set the range of the alarm. The function has no parameters but is of type float as it will be returning a float value in alarmRange. float readPot() Next, you read the analog value from the potPin and store it in potValue: float potValue = analogRead(potPin); You then carry out a calculation on this value to convert the values from 0 to 1023 that is read in from the potentiometer and converts it to the maximum and minimum range of the sensor, i.e. 0 to 254 inches. alarmRange = 254 * (potValue/1024); Then you return that value to the point where the function was called: return alarmRange; The next function is responsible for setting off the alarm sound. This is the startAlarm() function: void startAlarm() { asp.net mvc generate qr code .NET QR - Code Generator for .NET, ASP .

Generate , create QR Code in Visual ASP. Next you have a while loop. You came across the while loop in 3. The loop will run while the statement in the brackets is true. The parameter for the while loop is 1. This simply means that while the value being checked is true, the loop will run. In this case, the value being checked is a constant value of 1, so the loop always runs forever. You will use a return command to exit the loop. while(1) { Now you have a for loop that will sweep up through the frequencies from 800 to 2500Hz: for (int freq=800; freq<2500;freq++) { You play a tone on pin 8, where the piezo sounder is, and play the frequency stored in freq: tone(8, freq); Now you check the buttonPin using digitalRead to see if the button has been pressed or not: if (digitalRead(buttonPin)) { If the button has been pressed, the code inside the brackets is run. This starts with a noTone() command to cease the alarm sound and then a return to exit out of the function and back to the main loop of the program: noTone(8); return; In the next project, you will keep the same circuit, but upload some slightly different code to use the sensor for a different purpose. 1. Create a new user control named ProductDetailsAdmin in the UserControls folder. 2. You need to add controls to the form, as shown in Figure 8-32.
