Acceleration sensitive Led Matrix By TheRagingTowel A led matrix made of two identical 8×7 led modules, ATmega168 and a Freescale's MMA7260QT 3-axis accelerometer. I built this mainly to act as a n-sided D&D cube. for more details see http://itay.bazoo.org/projects/ledmatrix Tags: accelerometer, array, atmega168, avr, d&d, dice, display, diy, electronics, embedded, gadget, led, ledarray, ledmatrix, matrix, tilt 2 Downloads - Last from: http://downthisvideo.com/?url=http://www.youtube.com/watch?v=NWZV98KE_Ec (Your Blog here!) |

Motors and Microcontrollers 101 By nerdkits Curious about connecting a motor to your microcontroller? In this NerdKits video tutorial, we explore motors from an electrical perspective, and see how back EMF, resistive, and inductive considerations lead to the design of a motor control circuit. Finally, we show two demos, one with a motor controlled with a toggled digital output, and the other with pulse width modulation (PWM) to adjust the speed in proportion to the temperature. For more details, source code, and more, see: http://www.nerdkits.com/videos/motors...
