Acceleration sensitive Led Matrix see http://itay.bazoo.org/projects/ledmatrix 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.

Capacitive Touch Sensor: Learn Electronics with a Spooky Halloween Project Halloween is a great time to put your engineering prowess to work on a fun project. For this special Halloween project, we built a spooky candy bowl that lights up when an unsuspecting trick-or-treater reaches in. Using a microcontroller and some aluminum foil, we can build a capacitive proximity sensor that detects when a person's hand is nearby. For more details, explanations, and source code, please see: http://www.nerdkits.com/videos/halloween_capacitive_touch_sensor/ Tags: analog, atmega168, avr, capacitive, circuit, comparator, decay, dielectric, diy, electric, electronics, exponential, field, halloween, jack-o-lantern, jackolantern, learn, led, microcontroller, nerdkits, permittivity, project, proximity, pwm, rc, sensor, strength, timer, touch 1 Downloads - Last from: (Your Blog here!) |

Motors and Microcontrollers 101 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_and_microcontrollers_101/ Tags: 2n7000, atmega168, avr, back, breakdown, brushed, coil, control, current, dc, digital, electromagnetic, emf, inductance, microcontroller, modulation, mosfet, motor, n-channel, nerdkits, output, pulse, pwm, resistance, sensor, speed, stall, torque, transistor, triode, voltage, width, winding 1 Downloads - Last from: (Your Blog here!) |
