INTRODUCTION Our project aims to assist some organizations to send or help homeless people to shelters or let them rest in cars when the weather gets extremely cold. The GSM device I use in this tutorial is used for sent text message to van drivers so that they know which grates homeless people have rest […]

Introduction: Our group’s project, Crossing Guard, is aimed at providing safe environment improving for the vulnerable people when crossing the intersection in busy urban areas. An audio noise like “crossing” or “wait” is needed to indicate if it is safe to cross especially for blind people. In this tutorial, we will mainly use Interface SD Card Module […]
Introduction: Since this project is an add-on of current traffic light system and this project consists of two parts that will be installed in different locations in an intersection, we are adding a wireless communication part between two parts. We only need one-way data transmission, which is from the crosswalk to the traffic light […]
Building on SparkFun’s Force Sensitive Resistor code, this tutorial demonstrates one method for enabling a pressure sensor response after a set threshold has been consistently sensed over a period of time. There are many applications for setting pressure response after a set duration has past. One application is distinguishing the difference between a person (who […]
Introduction This tutorial shows how the Smart Light can work together with vehicle and crosswalk traffic light in the dark environment. We use two boards for the final prototype. One board (board 1) will include the photo resistor, crosswalk traffic light system, PIR sensor, transmitter, and SmartLight associated with the crosswalk traffic light system. On […]
Introduction Our project is about helping and locating homeless people under extreme cold weather condition. This tutorial aims to make the RGB light changes its color when the temperature changes. The RGB light is a warning signal for homeless people who sleep on the street. Blue indicates the weather is very cold and may threaten […]
Hello Arduino Users! In this tutorial, we will learn how to light up a RGB LED and power a DC motor using a pH sensor. This tutorial is part of my team’s water quality project. For our project, we will be monitoring sewage outflows using four different water quality sensors (including a pH sensor). We […]
INTRODUCTION This tutorial will allow you to define unique responses to the detection of an RFID tag by an RFID sensor. To demonstrate this, RFID tags will be identified into two categories, and each category will have a different response. A tag that does not fit into either category will also have a response. Group […]
Introduction The goal of our group project is to set up a smart CSO water purification system with a combination of four different types of water quality sensors, a simplified aeration installation, and active carbon. In this tutorial, we will use a turbidity sensor to monitor the quality of water (click here to know more about […]

Force Sensor Peak Detection
This tutorial gives an overview for how to determine the peak force read by a force sensor on an Arduino Uno board. There are many applications for this type of setup, but my particular one is for reading the weights of train cars as they roll over a single sensor. The algorithms shown here can […]
