Can anybody tell me how to configure an SD card, wifi-shield, and the serial monitor to all work simultaneously??? I'm trying to capture an image using motion detection and, afterwards, save the array of 100 images to the SD card. Afterwards, I...
Everything that happens on a micro-controller has to be known. This includes dealing with memory. Many people (myself included) have developed a wonderful set of code that can dynamically use and free memory through the standard malloc and free funct...
User interfaces can take up a lot of memory. That is why, while developing the Arduino User Interface I focused on developing a way to store things in Program Memory instead. It turns out that storing -- and then using -- program memory objects can b...
One of my first big micro-controller projects was called the Neonatal Closed Loop Oxygen System. When babies are born prematurely, they have to be fed very specific amounts of oxygen. Too little oxygen and they suffocate, too much oxygen and they can...
This is a quick post to show how easy it is to connect a DHT22 temp and Humidity sensor to an Arduino and have it output its reading on a web page that can easily be accessible from anywhere on the internetWith a little more work you can pretty up th...
For many years Morse code was a large part of the mandatory licensing examination in both Canada and the US. In order to get a basic license to transmit on amateur bands, a prospective amateur would have to commit him or hers...
This is the third post in the blog post series celebrating Arduino day 2014.. This post is about a low-cost mobile lab experiment kit put together by the talented folks at Minseg. This is an excellent example of the contribution Arduino has made...
This is the second blog post in a series of posts celebrating 10 years of Arduino! This series highlights how Arduino has powered a number of innovations in the field of education and engineering. Robotic arms are used extensively for num...
Happy Arduino day!!! Do you remember racing a car in a video game, bumping into your opponent, your joystick happens to vibrate and you could feel the collision? This is the science of haptics. Haptic devices provide users a sense of physical in...

Hey everyone.Just joined up here.I have all sorts of interests. I am building a diy cnc machine, a self steering kontiki, automated christmas display and salt water marine tank which includes lots of automation.I was recommended to this forum as it h...
NightShade Electronics is proud to present the energyShield! The energyShield is an Arduino shield designed with one simple purpose in mind: to help innovators everywhere power their projects without being tied to a wire. Watch the video H...
Attached is my first attempt at C language programming for my new Arduino UNO R3.I am unable to understand the VERIFIER's error messages. Any help would be really appreciatedBeauNew Member Robot ver. 1.0int Duration=0; // Define a timed va...
Hello, my name is Beau Palmer. Married with 2 adult children and 3 wonderful grandchildren. Retired telecommunications engineer. Interested in nearly ALL things electronic, electrical and electromechanical. I'll end here. If anyone receives this tran...
1) I understand that the board has 14 outputs on it. I would like to use these to control a board with 14 or 16 relaysNot sure where to look for this any ideas2). I know you can download a software program to control the Uno. Can I use somethin...
Dear element14 members, I am doing a science fair project where I am taking 10 readings from a photo-resistor and trying to take the greatest value to do something else. Is there a simpler code than making a lot of ...
I had a bit of a play with a run time clock module yesterday. It's an I2C device that I got as a cheap import from Hong Kong using the DS1307 chip.Basically once you've got the right libary it's really simple to use, you don't even need to set the ad...
I am trying to search for a code to couple the Centipede to the Arduino Mega2560, using the Cetipede 64 pin to work with a simple programme such as 1 input on the Mega and sequence of timings; int pin2 = 2;int pin3 = 3;int pin4 = 4;int pin5 = 5;...
Here is a video I posted with the description copied below of a simple slideshow project I made. It is rather easy for a beginner to put together and has some potential for adding more complex features. It can be done with any of the display shields ...
In this project using only an Arduino with an Ethernet shield.I’ll be controlling one LED and a servo, but you can apply this method to control a DC motors, buzzers, relays, stepper motors, etc.. Check this Video tutorial below ! (Includes demon...
For small robotic and other projects you can pick up small 28BYJ-48 stepper motors and gearbox with ULN2003ULN2003 driver boards quite cheaply. These motors are used in comercial projects like washing machines etc hence are made in very large quantit...
