For my first IoT project I wanted to build a Weather Station and send the data to data.sparkfun.com. Small correction, when I decided to open my account in Sparkfun, they were not accepting more connections, so I choose another IoT data collector thingspeak.com. Continuing… The system will be placed on my balcony and will retrieve temperature, […]
Timer interrupts allow you to perform a task at very specifically timed intervals regardless of what else is going on in your code. In this instructable I’ll explain how to setup and execute an interrupt in Clear Timer on Compare Match or CTC Mode. Jump straight to step 2 if you are looking for sample […]
The goal of this project is to build a cheap alternative to measuring CO2 ppm in the air. It’s a nice simple way to see over-time change in ppm using a cheap NDIR carbon sensor and a temperature/pressure sensor to achieve better accuracy. In this project you will need to: – Solder – Wire – […]
I have a solar power installation using an Omnik string inverter. Omnik is a China based manufacturer of PV inverters and they make extremely efficient devices. Optionally, you can install a WiFi module to make it “connected”. I am very content with the device, with two notable exceptions. It “phones home” to a China based […]
In this short tutorial we make an Arduino LCD shield. Updated 18/03/2013 Today we are going to make an Arduino shield with an LCD module. More often than not I have needed to use an LCD shield in one of my projects, or with the Arduino tutorials. Naturally you can buy a pre-made one, however […]
This example shows you how to make a HTTP request using an Ethernet shield. It returns a Google search for the term “Arduino”. The results of this search are viewable as HTML through your Arduino’s serial window. Circuit The Ethernet shield allows you to connect a WizNet Ethernet controller to the Arduino via the SPI […]
LED HEAD TED meet the world. I have always been interested in a bare-bones Arduino but never really saw the point if it was not practically useful, This is my entry into Little Bits contest, I tried to stay true to the ” little bits” theme and use…well little bits that I had lying around […]
I want to make a robo arm with less cost which draw cute pictures. That robot want to make my Daughter happy and it can able to dance. I saw a Cutest drawing robot in Kickstarter. I like it very much and want to make one such robot. So i go through my school life […]
This example is designed to be used with a Processing sketch. Processing is an open source programming environment. The application on the computer reads the sensors on the Esplora board and controls the buzzer and the RGB LED through a graphical interface. The image in the Processing application mirrors the Esplora board, so you’ll see […]
There have recently been a series of web query projects that use the miraculously tiny and affordable ESP8266 micro controllers. Most have involved the output going to a tiny screen with small graphics. The local YMCA in Anchorage just completed a beautiful remodel but lacked funds for decorative elements. I wanted to build them something […]
