In this Arduino limit switch tutorial, we’re going to talk about how to use the limit switch within our Arduino projects. The limit switch is a fantastic tool for use in projects that have motion control and automation. The limit switch can be used to tell the Arduino that a stop point has been reached. […]
The Arduino force sensor is a super neat sensor that you can use in your projects to measure if something is being pressed upon and to what degree. The force sensor is used in many devices that you might not expect. For example the drum pad! When you tap on a drum pad there is […]
Arduino RGB LED configuration! That’s what we’re covering in this tutorial! Most of the time you will be using LEDs that are a single color. Red, green, or blue for example. an RGB LED is basically three LEDs in one that can produce many thousands of colors! Please note this tutorial is not about WS2812b […]
In this tutorial we will cover the basics of the Arduino touch sensor. It’s one of the fundamental input devices available for the platform. I a touch sensor simply put senses when it comes in contact with a human, be it finger, toe, or even your nose. The touch sensor can be substituted in many […]
Learning how to use millis instead of delay is a key principle for learning the Arduino platform. The delay() function will cause all code executing on the Arduino to come to a complete halt and it will stay halted until the delay function has completed its delay time. We often refer to the delay() function […]
In this Arduino tutorial, we’re going to learn the basics of how to fade an LED with a potentiometer. As you turn the knob of the potentiometer the resistance changes. The Arduino will take this readings on the connected analog pin and then software will use a PWM signal at the correct frequency to light […]
In this Arduino Tutorial we’re going to learn how to control a piezo buzzer with a button. Pressing a button on your breadboard will cause the piezo buzzer to sound. In this tutorial we will be using a active piezo buzzer. If you’d like to do this with a passive piezo buzzer you can find […]
A piezo buzzer is a fantastic way to add feedback to users of your projects. In this Arduino piezo buzzer tutorial, we’re going to dive into the different types of piezo buzzers, how they work, how to wire them up to your Arduino, and write a sketch to control them. Before you know it, piezo […]
In this Arduino tutorial, we’re going to learn how to control a relay with a button. This is a very similar tutorial to our button LED control tutorial, but with a relay! The main difference being that a relay will allow you to control something of higher voltage than the Arduino can control directly. RELATED: […]
In this next tutorial on the Arduino platform we’re going to learn how to use a button to toggle an LED On and Off with the press of a momentary push button. This isn’t like turning a switch on and off, rather its controlled by logic in the Arduino’s microcontroller. The Arduino reads the state […]
