Technically, it is borderline safe. But the Arduino is rated for 12v max! If there is any kind of power fluctuations, your board will be fried for sure. You can either have separate power supplies or use a heavier and more reliable motor drivers. This one is outdated for heavy usage and it also over heats for bigger motors. It's only for beginners.
The shield is not capable of supplying power to three servos. If you are using only servo motors, remove the shield and use the servos directly. Just supply 5v from external to the power pins of the motor and connect the control pins to the Arduino. That might be the safest way.
That shield uses almost every pin indeed. But you can use A0 to A5 (the analog pins). And pin 2 and 13 are not used by it. If no servo motors are connected, you can also use pin 9 and 10. The analog pins are connected to the holes in the corner. It think it is a row of GND, a row of 5V and a row with A0 to A5. You can use the analog pins as digital pins : pinMode (A0, OUTPUT); The analog part is just an extra, beside that they are like normal digital pins
Is the shield's onboard LED turning on? If not, make sure the battery is plugged in correctly and the power jumper is in the right place. And 9v batteries will usually drain pretty quickly if you power motors with it. I would recommend lithium batteries.
Will a 9V battery power both the arduino and the motor shield? While running 2 motors at a given time? (I'm planning to turn two off, and use the other two afterwards therefore total motor count 4)
Hi There, Thanks a lot for the video. I want to use such a shield with a Arduino Mega. I want to connect 3 12V DC Motors. I want to controll the speed of every motor freely with a own potentiometer from stop to full speed, also I want to change the direction of each motor with a switch. Is that possible to realise? When I use the Mega, are the left I/O s free to use for something else or do I expect for example timing problems. Sorry, if my questions should be clear. I'm more or less new to this kind of arduino stuff. Best greetings.
Did you get and exit status 1 error or the PWM error where it says that the scope is not defined. I'm new to this and I'm using the Arduino R4 WiFi with the L293D v1 motor shield like in the video. What can I do. I also read online that the v1 motor shield doesn't compile and only the v2 does. Is that true? Thank you!
What is the maxi tension for the motors please? Can i use 24VDC motor? Thanks
The shield supports only upto 12V.
Can this motor shield running the 12 v dc motor? I would like to use single power source for arduino and 2 unit 12v dc motor, do you have any advise?

@@techtalkies1 thank you
Good stuff!
Thanks!
is there anyway i can connect a third servo??
The shield is not capable of supplying power to three servos. If you are using only servo motors, remove the shield and use the servos directly. Just supply 5v from external to the power pins of the motor and connect the control pins to the Arduino. That might be the safest way.
Next do on TCS3200 color sensor❤
Sure!
can we still use the spare IO pins?
That shield uses almost every pin indeed.
But you can use A0 to A5 (the analog pins).
And pin 2 and 13 are not used by it.
If no servo motors are connected, you can also use pin 9 and 10.

@@techtalkies1 thank you
Could you share what power supply to reccomend? I am using a 9V battery and cant seem to get my stepper motor to run.

No. A 9v battery will drain really quickly in a circuit like that.

Sorry for not replying sooner. Hope you got your solution.

Are you using the v1 shield?
It might need a different library import
@@techtalkies1yes I'm using the v1 shield. Could you paste the link to the library import that you mentioned or how do I get to it ?
Thank you
Try this old library.
github.com/adafruit/Adafruit-Motor-Shield-library
Ideally, you should get the latest v3 shield of possible. It's a good upgrade.
Nice, but is there a way to still have at least two available Arduino conectors for serial communication?
Sorry for not replying sooner. Hope you got your solution.
