Arduino Tone Frequencies to Produce Specific Musical Notes

The arduino connected to a passive buzzer can actually be used to create simple music. In order to do this, we need to know the frequencies associated with specific notes. The code below can be used to directly write musical notes to the arduino tone command. This will be covered in an upcoming lesson. Enjoy!

 

Arduino Program to Average and Sort Grades

In this video lesson we show how to create a program that will input a list of grades, sort them into descending order, average them, and then find the high and low grades. This is a classic first year college programming assignment. We take you through it step by step. For you convenience, we include the code below.

 

Arduino Uno R4 WiFi LESSON 36: Finding Average of an Array of Numbers on Arduino


 

Below is the code we develop in the video above. It inputs an array of grades, it averages the grades, and then finds the High and Low Grades.

 

Arduino Uno R4 WiFi LESSON 35: Understanding and Using Arrays in Projects


 

In this video lesson we introduce the concept of Arduino Arrays, and illustrate by writing a simple program which inputs and prints a list of grades. The code from the  video above is presented below for your convenience.

 

Using the Arduino Uno R4 Wifi to Measure Temperature and Humidity With the DHT11

In this video lesson we show you how to measure temperature and humidity using the DHT11 sensor. For your convenience, we include the code below which we develop in the above video. Enjoy!
