Introduction Liquid flow meters measure water flow and water volume. In this tutorial, I compare the flow rates of two flow meters and produce a signal when the two do not match. Parts Arduino Uno (x1) Liquid Flow Meters – Plastic 1/2″ NPS Threaded (x2) (https://www.adafruit.com/product/828) LED (x1) Breadboard (x1) Jumper wires (x9) Liquid Flow […]

In this tutorial we will learn how to use one arduino UNO’s, one arduino NANO and two NRF24L01 Transceivers to send CTA messages from a safe needle kit vending machine to a monitoring facility. What it does: The button is used as a quick remote response for seeking help with troubleshoots at the vending machine […]
Purpose: This tutorial will show you how to use the Arduino to program an ESP8266 WiFi Module. This module can be used to connect your Arduino to the internet. Parts: Arduino Uno Breadboard ESP8266 WiFi Module ESP8266 ESP-01 Breadboard Adaptor 8 jumper wires Notes: This circuit requires 3.3V for power. However, it is ideal if […]
Purpose This tutorial will teach you how to use the pulse-oximeter to detect blood oxygen level. Once the blood oxygen is detected, we wil know whether the driver is in danger of opioid misuse. Parts For this tutorial, you will need the Arduino Uno Kit and the MAX30102 Pulse Oximeter & Heart-Rate Sensor. To be […]
This tutorial will teach you how to code for circumstances where a condition needs to be set before further action can be taken: in this case, we are preventing a car from starting until an oximeter sensor in a glove registers a blood oxygen saturation in the drivers hand. However, due to the limitations set […]
This tutorial will show how to detect the fullness of a trash can by using an IR breakbeam sensor, and a RGB LED will change its color according to the changes. Parts list : Arduino Uno IR Breakbeam Sensor Wires (of various lengths and ends) An LED light bulb 3 330 ohm resistor Infrared (IR) […]
In this tutorial, we will learn how to use button, DC Motor, LED and Piezo buzzer with the Arduino board to prototype an opioid-impaired driving guard system for vehicles. This system is part of our Driver Guard SOS project, I am working on this project with my group mates Gil and Jacey, who each is working […]
This tutorial shows you how to display written messages on an 8×8 LED Matrix. Emitting such messages is part of a larger project to respond to an opioid overdose through sensor responses. In this case, the LED matrix will display the message: “SOS Call 9-1-1” to bystanders should an individual be in danger of an […]
Buttons and LEDs are basic parts that can be easily programmed with Arduino, but this humble hardware can be critical for creating prototypes that interact with users in a certain way. Colors, flashes of light, and even vibrations can change the way that a user interacts with your prototype. This tutorial aims to provide a […]
Overview Nowadays people rely on cell phones, so emergency landlines in public spaces are hard to find. For situations when a connection is needed, it can be a tough decision which communication technology to deploy. The popular GSM (Global Systems for Mobile Communication) boards are becoming harder to integrate as 2G and 3G are becoming […]
