Introduction: This tutorial will show how to detect the fullness of a trash can by using two force sensitive resistor (FSR), and a RGB LED will change its color according to the changes. Basically, FSR is a resistor which can change its resistance depending on how much pressure it receives, and it is very sensitive […]

Writing and Reading Data to an SD Card
Occasionally, it is necessary to store and recall more data than can fit on a standard Arduino board. With the addition of an SD data logger shield, we can store more data, but still access when needed. In this tutorial, you will sense light intensity through a photo sensor and store the readings every second […]
This tutorial tells about how to light an RGB LED in accordance with a PIR motion sensor. The RGB LED can display a vast array of colors. By following this tutorial, you can realize the scenario that if the PIR detects nobody around, the LED will be on in a smooth and colorful pattern. When […]
Introduction The idea for this tutorial came about as a way to prototype a solution to a common urban problem: overflowing dumpsters. City streets departments usually pick up trash on a fixed schedule that does not take into account how much trash there is, and residents dump trash whenever their household bins are full. What […]
Hello Arduino world! At the end of this tutorial you will be able to use a piezo element to activate lights on an LED strip. Before we begin, let’s better understand what is occurring with piezoelectric sensors. Piezoelectric sensors utilize the idea that everything gives off vibrations and shocks when it moves, and therefore, this […]

Weighing Sensor Tutorial _ Draft
For our “Safe Bike Path” project, weighing sensors are necessary to test if there is any car running or turning over the bike path. In our prototype, we are going to use the load sensor as follow: The maximum weight will be 50 kg /110 lb. We went through some existing tutorials and found that […]
In this tutorial, I will demonstrate how to control an Addressable LED Strip using any arduino sensor. The examples I will show below will use a potentiometer and a photo cell. Needed parts include: An Arduino A breadboard An addressable LED strip Any sensor About 8 wires External power supply (if using a long portion […]

LCD Screen Tutorial
Hello everyone, in this tutorial I will cover how to program and wire an arduino LCD Screen. Essentially how this works is the arduino prints to the LCD, similar to how it would print to the serial monitor, except this is a more easy to see visual. So, First a parts list. You will […]

Creating a non-invasive current sensor
In this tutorial, we will be setting up a non-invasive current sensor to measure current flow. Material List One Arduino Uno One Soderless Breadboard One 10uF capacitor Two 10k Ω resistors One 33 Ω resistor One Non-Invasive Current Sensor rated at 100A Wire Stripper or 3.5 mm audio jack Optional: 9V battery connected to Arduino […]
In this tutorial, I will cover programming one Arduino board to act as a “controller” and send a signal to another board, triggering the second Arduino to respond by changing the color of the RGB light. This project is a helpful overview of how inputs on one board can trigger outputs on other boards. Communication […]
