Welcome to the Arduino Based Project which consists of Passive Buzzer which differs from Active Buzzer in some measures. Its functionality is being described here.
The Passive Buzzer is the slightly shorter one, with the electronics exposed on the bottom. You have to send it an AC "sound signal" via the Arduino. The Arduino needs to generate the "tone". Can create music. It takes processor-time to generate the sound so other processes might slow down. Notice it does not matter which leg you use for positive or negative. The pin can be connected to a passive piezo buzzer or other speaker to play tones.
Only one tone can be generated at a time. If a tone is already playing on a different pin, the call to tone () will have no effect. If the tone is playing on the same pin, the call will set its frequency. After downloading the program, the buzzer experiment is completed.

Welcome to the Arduino Based RGB LED Project. White light can be produced by mixing different colored lights together
the most common method is to use the primary colors red, green and blue (RGB). As this mechanism involves the blending and diffusion of different colors, this approach is little used for the production of white lighting due to the tendency of it to have a slight tint or hue. Nevertheless, this method is particularly interesting for effect applications because of the flexibility of mixing different colors.
In principle, most perceivable colors can be produced by mixing different amounts of three primary colors, and this makes it possible to produce precise dynamic color control as well. Utilizing the DMX control protocol, it is actually possible to achieve a color palette of over 16 million shades!
Each color scale it is possible to select 256 levels or shades of that color. If you have three primary colors and each one can have 256 different shades, then by mixing them together you can mathematically generate 16.7 million different colors. 255 x 255 x 255 = 16,581,375. RGB LED controllers work on a much simpler principle. They alter the power on each of the three channels (red, green and blue) to create a specific color mix. Directly copy the code into Arduino IDE, and click upload .wait a few seconds, you can see a full-color LED.

Welcome to the Arduino Based LDR Project which is based on the photoelectric effect of the semiconductor. Its basic working principle is that if the incident light is intense, its resistance reduces; if the incident light is weak, the resistance increases. Photo varistor is commonly applied in the measurement of light, light control and photovoltaic conversion (convert the change of light into the change of electricity). Photo varistor is an element that changes its resistance as light strength changes. So we will need to read the analog values. We can refer to the PWM experiment, replacing the potentiometer with photo varistor. When there is a change in light strength, there will be corresponding change on the LED. After the connection, let's begin the program compilation process. The program is similar to the one of PWM. After downloading the program, you can change the light strength around the photo varistor and see corresponding brightness change of the LED. Photo varistors have various applications in our everyday life. You can make other interesting interactive projects base on this one.

Welcome to the Arduino Based Project which consists of 10K Potentiometer. Here, we will convert the resistance value of the potentiometer to analog ones and display it on the screen. We use the analog interface 0. The A/D acquisition of Arduino 328 is in 10 bits, so the value it reads is among 0 to 1023.
First, we need to set the baud rate in void setup (). Displaying the value is communication between Arduino and PC, so the baud rate of the Arduino should match the one in the PC's software set up. Otherwise, the display will be messy codes or no display at all. In the lower right corner of Arduino software monitor window, there is a button for baud rate set up. The set up here needs to match one in the program. The statement in the program is Serial.begin(); enclosed is the baud rate value, followed by statement for displaying. You can use Serial.print() or Serial.println () statement. The sample program uses built-in LED connected to pin 13. Each time the device reads a value, LED blinks.
When you rotate potentiometer knob, you can see displayed value changes. The reading of analog value is a very common function since most sensors output analog value.

In an LED code, we took 1000 ms as the delay between HIGH & LOW, means an LED remains 1 second HIGH & 1 second LOW. In this example, Arduino takes the voltage form the center leg of pot & converts it to digital form (0 - 5 to 0 - 1023). So, when we rotate the nob of the pot to 0V, we are actually decreasing the time between HIGH & LOW & when we rotate the nob of the pot to 5V, we are actually increasing the time between HIGH & LOW. A simple but effective way to control the blinking speed of an LED.
