Circuit bender Dr. Bleep built this sweet Arduino-compatible drum machine, the Bleep Drum, with four sounds, four selectable sequences, tap tempo, record and playback, and more. Of course it’s open source and eminently hackable.Filed under: Arduino, Electronics, Music
One of the best things about the Ultimate Microcontroller Pack is that there's a multitude of projects you can do without sourcing additional components. This variety makes it a great choice for both beginners and advanced users.
The Monday Jolt is a new column about microcontrollers and electronics that appears in MAKE every Monday morning. Lego Mindstorms NXT is a fantastic educational robotics set that teaches kids and adults skills ranging from engineering to programming. Nevertheless, wouldn’t it be cool to enhance those Lego robots with Arduino [...]
With all the microcontrollers and single board computers on the market, sometimes it's hard to see all your options. That's why we made up this quick reference sheet for the 8 most popular boards we sell in the Maker Shed.
As some of you may know I am in the process of making an R2-D2 like robot.
The base of the robot has two drive wheels and two castor wheels. The drive wheels are powered by continuous rotation servos.
The wiring is as follows:
7.2V Ni-MH 1800mAH battery > Regulated down to 6.6V > Powering the two servos > Grounds connected to Arduino > Signal cables connected to Arduino.
Want to learn about Arduino from the ground up? The Mintduino Game Pack teaches you all about basic electronics, breadboarding and programming piece by piece. When you finish, you'll have a fun, two player game to play with a friend and a firm grasp in the world of microcontrollers. 
Hello all
This is my first post in this forum and I hope you can help me. I just got a Rover 5 ( the 4 wheel edition) and the Dagu 4 channel motor controller.
Everything is connected with my Arduino Mega and I have no problems to control the motors and read the current amp value from the motors. I noticed that the motors are consuming up to 1.6 A and I think this is too much ? The Rover was not touching the ground and the default chain was mounted on the tire ?
Should I try to make the chains more loose ?
hi, im a twelve year old boy who is not an expert AT ALL, but knows the basics
i've made bristlebots, speaker tones, dc motor cars and other stuff
BUT
when i have to program in arduino UNO i just copy other codes from other people
cause... I dont know how to program at all!!!! i think arduino's language is c,and i don't know how to program
anybody knows how to program arduino
and can give me a little tutorial about key words and etcetera like setup, delay, control of dc motors sensor etc...
Amanda Ghassaei built this fun Arduino-powered noisemaker: The glitchbox is a sample-based drum machine used for live audio or MIDI sequencing. The buttons on the front of the instrument play back nine audio samples stored in its memory. A switch on top records and loops sequences of these samples. Once [...]
