Arduino-Using Shift Registers With Ultrasonic Sensors

The HC-SR04 Ultrasonic range sensing module is great for sensing distances that can be used as an input for your Arduino projects, but using multiple (more than two) can quickly cost you a lot of pins. This basic Instructable gives you the code and basic instructions to use the 74HC595 8 bit series to parallel shift register so you can connect up to 8 HC-SR04 modules (16 IO pins) while using only 4 Arduino ...

Arduino Weather Station with DHT11 and BMP180

Introduction In the previous tutorial I showed you how to build a weather station using only the DHT11 sensor and I said the readings from this sensor is fairly accurate. In this tutorial, I will be using the DHT11 to measure only the humidity and BMP180 to measure pressure and temperature. That’s because its readings are more accurate than the DHT11 temperature readings. Project Parts I will be adding only ...

Synesthesia Mask

https://youtu.be/9vLSuLL9xLA Inspiration What if I told you that 2+2=Red!?!? What!?! I know this sounds crazy but for people with synesthesia this might be their reality. Synesthesia is defined as "the production of a sense impression relating to one sense or part of the body by stimulation of another sense or part of the body." This is a complicated way of saying that people with synesthesia have blended s ...

IOT SAFE KEEPS LATCHKEY KIDS’ PHONES ON LOCKDOWN

Phones are pretty great. Used as telephones, they can save us from bad situations and let us communicate while roaming freely, for the most part. Used as computers, they often become time-sucking black holes that can twist our sense of self and reality. Assuming they pick up when you call, phones are arguably a good thing for kids to have, especially since you can hardly find a payphone these days. But how ...

Arduino Weather Station using DHT11

Introduction Using a display to view the temperature and humidity of your environment can be possible using the DHT11 or DHT22 sensor with the easy to use Arduino microcontroller platform and that’s the goal of this project. For this project, we will be using the 16×2 LCD display module to display the temperature and humidity readings gathered from the environment using the DHT11 temperature and humidity se ...

Simple Arduino-based Thermometer

Building an Arduino project isn't just about making all the components talk to one another. It's about creating an actual object or prototype out of your small creation, and giving it that extra touch that makes it unique. For this next project, we took some very basic components: a one-wire temperature sensor and a 7-segment LCD. For the extra flavoring, we used SUGRU, a really cool material that works gre ...

Get Sensor Data From Arduino To Smartphone Via Bluetooth

Hariharan Mathavan at allaboutcircuits.com designed a project on using Bluetooth to communicate with an Arduino. Bluetooth is one of the most popular wireless communication technologies because of its low power consumption, low cost and a light stack but provides a good range. In this project, data from a DHT-11 sensor is collected by an Arduino and then transmitted to a smartphone via Bluetooth. Required P ...

Arduino Sunflower – an Electronic Sundancer

Maker is always sensitive to the new and funny things. One day, I watched a video, in which the sunflower moves along with the sun. I had a sudden insight then. Why can't I make a electronic device inmitating this biomechanism. In the following days, I began to carry out my solar tracker project. I selected the crowtail as the microcontroller board, and picked up the componets and accessories in our warehou ...

B-SENSOR: DIY PRESSURE CUSHION

This project examines how interface pressure is a key risk factor in the development of pressure ulcers. Visual feedback of continuous interface pressure between the body and support surface could inform clinicians on repositioning strategies and play a key role in an overall strategy for the prevention and management of pressure ulcers. eTextiles are made using techniques and materials that make it so elec ...
