In this tutorial, we are going to create a wireless communication with Arduino using RF transmitter and receiver modules. RF Receiver on the Right and RF Transmitter on the Left The RF Transmitter and Receiver Modules are very small in dimension and have a wide operating voltage range (3V-12V). They operate at 315Mhz and can be […]
This tutorial explains how to control the rotation of two servos based on the combination of input from a PIR motion sensor and a force sensitive resistor. The scenario set up here ithat when the PIR senses a person nearby and the FSR is not sensing pressure at the same time, the servos will spin […]
THE PROGRAM In this tutorial, we will 1) set up a gesture sensor that can detect to which direction an object is heading and 2) respond with a row of LEDs that will light up in a timed sequence if the object is headed toward it. This tutorial was developed as a prototype project for […]
This tutorial will guide you through creating an LED bar graph that responds to data collected by a sensor, and produces a visual representation of the data. The example demonstrated above uses a photo resistor to determine the brightness of the surroundings. A photo resistor is a sensor that responds to changes in light by sensing […]

Using Distance to Activate Light
In this tutorial, I’ll explain how to make a ultrasonic sensor use distance to activate an LED. There are lots of creative uses for this. Read on to explore- For me, this is a part of a larger project to make a bike path that automatically illuminates when being used. Two of these sensors will […]
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 […]
