Controlling DC motor with AVR ATtiny13 PWM and ADC Project

Its interesting to explore what we can do with this tiny 8 pins; 8-bit microcontroller. The ATtiny13 is the smallest and cheapest Atmel AVR 8-bit microcontroller families but yet, its loaded with sophisticated peripherals such as two 8-bit PWM channels and 4 channels 10-bit ADC.

Could you elaborate me what do you mean by controlling the wind turbine generator.

Thanks, but on this demo I used ATTiny13 (8 pins) which have 4 ADC channels (ADC0, ADC1, ADC2 and ADC3) not ATTiny2313 (20 pins) as you said, which is doesn't have the ADC peripheral at all.

or just use a potentiometer

@mrroboto8269 The whole point of PWM is that its a method to interface the motor to the uController. A pot can be used to control pretty much anything, but there is no fun in turning the pot yourself is there? Once you have hooked it up to your uController, you can add all sorts of functionality including implementing a digital control loop. PWM had the added bonus of being a lot more efficient.

@mrroboto8269 nope. controlling fans with a potentiometer doesnt work well. plus with pwm you can remote control them.

Nice.

i like it!

Hey this is a great video. I am doing a project on wind turbine. How can i use atmel chip to control the generator? can you help me here?

Cheers mate

[bobsonenzo]

how did you connect the motors to the pins on attiny? how did you change pwm rate of that blinking led?
