Arduino Tutorial 24: Understanding Passive Buzzers

In this lesson we show you how to incorporate sound into your project using a passive buzzer. Passive Buzzers have the advantage that they are less expensive than active buzzers, and you can more precisely control the tone. This lesson will show you how to hook up the buzzer, and then how to code the arduino to produce different tones.

If you want to follow along at home, an official Arduino Uno R3 is available HERE. In this new series of lessons, I will be using the sensor and other components found in this KIT.

In this new tutorial series we will take you step by step through creating a 9-axis IMU capable of monitoring an object’s orientation in 3 dimensional space. In this first lesson we introduce you to IMU and 9-axis sensor basics, and outline the gear we will be using in these lessons. To play along at home, you will need an Arduino Nano, and an Adafruit BNO055 Inertial Measurement Sensor.

Arduino Tutorial 23: Changing Tone of an Active Buzzer

In this lesson we show how you do have some ability to adjust the tone on the Active Buzzer to make a sound or alarm that is a little more interesting. If you want to make notes or play simple songs you should use the passive buzzer, but the active buzzer can be adjusted somewhat.

The video above takes you through the hookup and the steps. Also, the code used in the example above is:

Arduino Tutorial 22: Understanding and Using Active Buzzers to Add Sound to Your Project

In this lesson we show you how to add sound to your Arduino project using a buzzer, The kit contains two buzzers, an active buzzer and a passive buzzer. The active buzzer is the easiest to use, as you just need to apply 5 volts to it to get it to go off. In this lesson we show you how simple it is to use the active buzzer with Arduino. In future lessons we will show you how to use the passive buzzer.

The advantage of the active buzzer is that it is easier to use. Just apply 5 volts, and it goes off. The advantage of the passive buzzer is that it is cheaper, and allows you more control of the tone, or pitch of the sound produced.  If you want to follow along at home, an official Arduino Uno R3 is available HERE. In this new series of lessons, I will be using the sensor and other components found in this KIT.

Arduino Tutorial 21: Understanding and Mixing Primary Colors with an RGB LED

In lesson 20 we showed you how to connect up an RGB LED, and how to program it to get the primary colors, based on input from the user. In this lesson we look at mixing colors and getting a wide array of colors from the LED by mixing the R, G, and B channels. As examples, we use RGB mixing to create Cyan, Magenta, and Yellow. These are just examples, and any of the in between colors can also be mixed.

If you want to follow along at home, an official Arduino Uno R3 is available HERE. In this new series of lessons, I will be using the sensor and other components found in this KIT. 

The video shows how to connect the circuit, and also takes you step by step through the code. If you need extra help, the code is included below.
