I added it to reduce noise and I attached it across the two terminals on the motor.

Hi, I am using a sn754410 to control a motor of 1.5-3v(a standard dc motor). I managed to get it to work with a power supply of 3V, but once I put my 0.1 capacitor, the motor does not do anything. Any suggestions to get it working ?

Oh im sorry, I am not going to put a sensor, im just trying to get two motors running for now. Thanks for the tips though!

okay, but what I meant to ask was that is it necessary to double my power source(double the voltage) to control two motors?

Can you clear up your question, I am having a bit of a hard time understanding what"volts does it drop" means.

Thanks for the diodes warning, I knew it was an odd idea putting diodes in the circuit. Also, what is the "sensor" that you are talking about?
37  Using Arduino / Motors, Mechanics, and Power / Re: Power for 2 motors on: December 27, 2012, 02:04:50 pm
Currents up to 1 A at voltages from 4.5 V to 36 V

Ah, that's great news. Also, what is considered a low current motor? Are standard FA 130 motors low current?

Hi,
I've been recently at work trying to build an autonomous tank with an Arduino. I am using an Sn754410 motor driver IC to control two motors, each 1.5-3V. As a power source for both motors, should I have a voltage of 3v which is good for one motor) or a voltage of 6v(since there are two motors)?

Hi,
My question is wheter it is possible to have 2(two) Sn754410 chips on one breadboard hooked up to a single Arduino UNO. The goal of this is to be able to run 4 motors.(2 motors from each Sn754410). Also, will I need to add more power supply to handle the 3rd and 4th motors?

But my motor driver already has internal diodes in it. Also, do I put a resistor across the motor terminals where the capacitor goes?

Also, does it matter if I use a ceramic or aluminum capacitor. Because I noticed the ends of the aluminum are different size. And finally, is it mandatory for a motor short term?

Hi,
I am trying to build a robot tank with the motor driver Sn 754419ne. So my motor is a 6-12V motor, and I am using a power supply of 6V( 4 AA batteries). So I hear that I should attach a capacitor of 0.1u. My question is what does the capacitor do and how am I supposed to connect it to the motors( Do I connect it to the 2 little terminal on the motor?)
Thanks

Is the installation for the 1.1 version?

Hey, I recently bought an Adafruit Motor Shield 1.1 for my Arduino UNO. Lately, I've been trying to program it but it hasn't been working(because of serial port). However, I want to make sure that I have a very simple program that properly lets a motor spin forward. That's it. Because of so many different types of motor shield programs, its confusing to figure out which one works. So, if it isn't any trouble, can anyone send me a sample sketch for an Adafruit Motor Shield 1.1 that turns on 1 DC motor?
