Transistor / MOSFET tutorial How to use an N channel MOSFET to turn anything on and off. Also, remember to put a 100k resistor between gate and ground if you want your FET to stay off by default!

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!) |
