LM324 ST's dip motor driving

hi, well i wanted to build a quadricopter or something so i went a took look at prices... Maybe next time :fearful: :sweat_smile: :sweat_smile: :cold_sweat:

but i found out 3 LM324 from my old stuff i want to know are they useful for controlling dc motors??? also.. how should i use theM? are they useful for quadricopter or heli ones!!!! how to use them..?

Have you looked at the LM324 datasheet?

It's always a great starting point.

Totally useless for the purpose.

According to the datasheet, drive capability is strictly limited to less than 20 mA - similar or in practice, less than that of the ATmega chip itself. Can drive a LED.

You will find that it will almost certainly be most economical to build a quadcopter from a kit. Further, if you have some notion of developing the software yourself, you should consider this only after you have built the kit and gained experience with it. There are some "open source" projects ("Arducopter") which form the basis for this.

Just found it on line follower robot! So i can drive a non quadri motor whit it??? If yes any help on how to use it?

Hi,

If you are referring to the LM324, if you look you will see that the line follower does not use the quad opamp chip to directly drive a motor. The opamp is probably used to handle the sensor circuitry. The motors will be controlled by some relatively higher current transistors.

ok:) finding motor drivers or basicly anything in this god damn country!:smiley: so i got a llittle bit happy for a sec tought maybe i can use it!!! even couldn't find transistors !!!!

couldn't find attiny ! :smiley:

thanks anyway! there was 3 of them on the whole robot and nothing else ! 1 for line following head second for light seeking and third for wall avoiding!:smiley:
