Ever come home in the rain to find the door locked and your keys elsewhere? No? Lucky you then! For those who have had such an experience or never wish to, this project will let you open your garage door with nay but a smartphone/tablet/laptop/WiFi-thing and your super secret password! After all, who leaves their […]
Hello again. Today I’d like to show you the Auduino. That’s right, the Auduino is a Lo-fi Granular Synth that works on arduino. It uses some analog pins and a digital pin. I had loads of fun making and playing with it so I’d love to show you how to make it. Sketch created by […]
We built a pseudo Etch-A-Sketch emulator that modifies its appearance based on the user’s environment – the temperature and light conditions. Instead of only drawing horizontal and vertical lines, we can draw curved lines by changing the slope of the current line to be drawn. We use two potentiometers to serve as the knobs of […]
In this critical making project, we will be making a personal iDial, which will give you, the wearer, the ability to reflect on your personal identity in a private space, and then spatially and temporally dislocate your ‘private self’ into public conversation! You might be thinking, ‘this device looks ridiculous’. Well, that’s the point. This […]
Laser Command is a game which I build using a 8×8 matrix LED and an Arduino Mini. This game was developed as a “sample” class project in S10-05833 Gadgets, Sensors and Activity Recognition in HCI. The class is taught by Scott Hudson at Carnegie Mellon University, and I’m doing TA for the class. The name […]
When I was a kid, I loved playing with Estes Rockets, so I decided to get back into the hobby but using all of my maker skizzls. So here’s a really cool Arduino Rocket Launcher launching 3D Printed rockets from my MakerBot Rep2! Enjoy! Fully Open Source for anyone to make! Arduino Code on GitHub […]
We are going to make an Arduino control LED Piranha Plant :] Step 1: What you’ll need Arduino Uno 9 Resisters 9 LEDs – Red, Yellow, Orange is best since they need less amperage PIR sensor 9v battery arduino wall plug (you’ll be cutting the connection so that you can connect it to the battery. 12v […]
“THE CUBE” is a 3D jigsaw puzzle, with the added feature that a puzzle piece vibrates for approximately a second when it is placed in the correct place in the puzzle. We accomplished this by building an electrical design such that a circuit delivering power to a vibration motor was completed each time a puzzle […]
Hello, I’m David and in this instructable I’ll show how I made this hexapod whose name is Hexdrake. Since I was 16 I became interested in electronic and later in robotics. After getting some level and programming skills using arduino I decided to build a robot something more interesting than a simple robot with two […]
Connect the Arduino outputs with 5 volt power to the relay coils. Use a separate 9 or 12 volt battery for powering the motor. Connect the 9 or 12 volt power to the relay contacts and the motor. Be sure to avoid connecting the 9 or 12 volt power to any of the Arduino input […]
