Find IP Address via Morse Code

Have you ever connected your Raspberry Pi to a new Ethernet cable but don't have a monitor to see its new IP address? Or maybe you don't want to connect a monitor, keyboard, and mouse to search for the IP address when you don't plan on using any of the three? Morse Code This project will run a Python script on startup that grabs the IP address of your Raspberry Pi and outputs it to a GPIO port through Morse ...

Making the LED Installation at Visit Trondheim

NICE and Bjørke Arkitektur had this awesome idea on how to create a really mesmerizing entrance at Trondheim’s new tourist information, named Visit Trondheim. It should among other things include a moss coated interactive LED installation. As you may know, LEDs is something we really like working with here at Norwegian Creations. And luckily for us, Bjørke and NICE knew this, so they let us take part of thi ...

Raspberry Pi 2 IoT: Thingspeak & DHT22 Sensor

Introduction This project uses a Raspberry Pi 2 to collect temperature and humidity data from a DHT22 sensor, which is then uploaded to the ThingSpeak Internet of Things platform to be displayed in real-time. This write-up is primarily intended to serve as documentation for the project, but may also be of use as a tutorial for others. It assumes a beginner skill level and that you are running the Raspberry ...

Windows 10 IoT Plant Monitoring System

Project Intro This project is aimed to create a plant monitoring and watering system. The main task is to control the servo, relay and collect the soil humidity data from the plants. Huge amount of the sensors use analog signal as output but the Raspberry Pi doesn’t have an analog-to-digital converter. To solve this problem, I used an outer ADC module and an Arduino gateway because they have built in ADC. W ...

Home Control with a Raspberry Pi and Z-Wave

Intro In a previous post, I showed you an Arduino based controller to manage the lighting system in the house. Such a device is useful for handling the basic 'electrical' stuff such as lights, doorbells, gates, knobs and buttons. For other home automation/control desires, you often need to put special purpose devices in difficult locations, such as roller-shutters near the windows, RGB-controllers in the ce ...

Conexant 2-Mic Hands-Free Alexa on RaspberryPi

Overview This guide provides step-by-step instructions for setting up an Alexa prototype using a Conexant AudioSmart 2-Mic Development Kit for Amazon AVS and a Raspberry Pi. It demonstrates how to access and test AVS using the Conexant development kit, our Java sample app (running on the Raspberry Pi), a Node.js server for authorization (running on the Raspberry Pi), and a third-party wake word engine that ...

Pi to Azure to Alexa

Overview This project is about surfacing information from a Raspberry Pi through an Microsoft Azure infrastructure to an Amazon Alexa Skill. This could be an architecture that would support telemetry data collection over time by automating the collection, transport and storage of data from a Raspberry Pi. Maybe the most obvious example of a system like this would be a weather station that cyclically collect ...

Day & Night Home Security Solution

This project is started to catch the person who roams near my house. I don't know my house is perfectly safer than other house. We need to protect by ourselves to keep family. Basically CCTV is able to capture the image when some one comes and goes like black box in the car. But there are required to work during the day. How to detect the people during the night? Are you going to turn on the light? I don't ...

Temp. and Humidity Sensor with a CR2032 for over 1 year!

Intro This article will discuss and demonstrate how to build a remote Temperature and Humidity sensor based on a Whisper Node and a DHT11 (worst sensor ever, I know)., capable of running for well over a year on a single CR2032 coin-cell. The remote node will be configured to transmit data every 60 seconds to another Whisper Node, acting as a gateway/base station and located 100 meters away. The data will be ...

Candy Counting Robot with the Raspberry Pi

In this project, we took the tried-and-true robot costume and gave it some life with the Raspberry Pi, GrovePi, and a handful of Grove sensors. The costume is a standard robot costume, but with a candy-counting machine attached that talks! When a piece of candy is placed in the robot, it flashes its LEDs, thanks the candy donor for the piece of candy, and announces the candy count. We use the Raspberry Pi f ...
