Introduction Our group’s project focuses on improving pedestrian crossing safety for the vulnerable populations. A traffic intersection prototype needs to be built for the setting. Therefore, in this tutorial, we will use simple electronic parts to set up a typical traffic intersection including traffic lights and pedestrian crossing signals. Parts List In order to accomplish this project, you will need: […]
Introduction In this tutorial, we will learn how to use the 1) Ultrasonic Sensor 2) Servo and 3) LCD Screen with the Arduino Board to prototype a toll-gate for vehicles. This system is part of a larger train system I am working on with my group mates Leo and Neil, who each has also written […]
Introduction Our group’s project, SmartLight, aims to detect the presence of pedestrians on crosswalks and notify drivers about the presence of pedestrians through customized LEDs around both vehicle traffic lights and crosswalk traffic lights. Hence, there are two things to consider at the very initial stage: 1) How to detect the presence of people? 2) […]
Adafruit has an awesome tutorial on properly wiring and testing your Fona808; you can find it (here). If you want a description of the chip components and required accessories, you can find that (here). This tutorial is based on wiring to an arduino, so make sure you look at the correct tutorial (i.e., not the […]

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 […]
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 […]
