To give it a kick start I downloaded the library USB_Host_Shield_20. I'll be waiting for your reply.I bought a board last week. I hope the pics are enought for you have an idea about what I am doing.
I hace always use it for testing, and this circuit worked before with this power supply. PD: The external supply is an AC adapter to DC 9v and 0.85A. In the same schema I connect the external supply to the Arduino, and it doesn't work!Īnd connecting the external supply directly to the motor shield, doesn't work at all:
In this way it works, but the power from the PC is not enought to feed the motor shield and DC motors (ignore the power jumper I forgot it only for the photo). Pluggin the motor shield to the Arduino (power and pins): Now the conection to the motor shield with the wires:
In these 2 ways, it works perectly (Note in the second pic, the external supply is conected to the motor shield): Well, I don't have a HD camera but I did it.Īnd an Arduino MEGA 2560(it doesn't need a pic)
PD: Sorry for my very very bad english Gocht Posts: 12 Joined: Sat 5:38 am But before change this values I connected de motor shield away from Arduino, using wires to connect it (I read the documentation and I am using 4 DC motor, so in the FAQ link it says motor shield uses pins: 3,4,5,6,7,8,11,12 and power), but it does not work! I try to make it run FORWARD and suddenly the motors stop and I can not understand why. I think the motor shield and USB host shield are using the same pins on the Arduino, I have been checking the library and I found the declarations of the pins on Arduino. i'm using an Arduino MEGA 2560, and during the first test it worked perfectly! (when I use just the Arduino and the motor shield) but now I need to use a USB Host Shield too, then I got some arratic functions. I have got a motor shield for Arduino, it's compatible with Arduino UNO and Arduino MEGA.
