Having problems with Arduino Motor Shield

Hardware
1

Hi guys!
I am using Arduino Motor Shield. No energy flows to 2 of the DC motors pins. If I make only those pins to work, no voltage gets there. Tested with a multimeter. But when making the other 2 pins to work, both pins are getting enough voltage. Need help...

show schematic and sketch

Should i send you the pic of the circuit?

Above are the pic and the code

Motor 1 and motor 4 are working, but motor 2 and motor 3 ain't even getting any voltage (checked by a multimeter), even when uploaded code in the arduino for only those pins to work

6

what board are you using?

7
8

I'm using Arduino uno

9

You are using 4 motors. Take a look at page 8 here. It shows how many pins the shield uses with all the motors active. Doesn't leave much, not even SPI.

10

I have read it. I am using no such pins that are being used by the shield

11

do you have another/second board to test?

12

Digital pin 11 and 12 are the Uno SPI. Can't use #include <SPI.h>

Digital pin 11: DC Motor #1 / Stepper #1 (activation/speed control)
Digital pin 4, 7, 8 and 12 are used to drive the DC/Stepper motors via the 74HC595
serial-to-parallel latch

13

that's a lot of motors!
are you using a 4A power supply?

14

Sorry, I don't

15

I used d2 instead of d11 for rf modules, using this code:

RH_ASK driver(2000, 2);

16

I increased the power supply to the shield and the problem solved. Sorry for doing such a silly mistake. :sweat_smile:

Thank you all for helping... :smiling_face:

But now I have one more problem, please help if you can. Here is the post:
