hello

Sazan, the only additional thing you need is a power supply - and a motor. You'll have to provide the 5-18 volts to the controller board from separate power.

thank you for answer

the motor I have has the attached datasheet. Is it good to use it with ardunio? or I have to change it .

thank you.

really I want to change the input voltage and read the output voltage. I want to convert the rpm speed to voltage. could you please instruct me in  steps how to connect the motor and read its input voltage and output voltage

in your opinion. what should I do. Really I need help lam lost

From the photo of your motor shield, it seems that you have the Adafruit Motor/Stepper/Servo Shield for Arduino kit - v1.2 - or a clone.

https://www.adafruit.com/products/81

They have a tutorial: https://learn.adafruit.com/adafruit-motor-shield

Follow the steps on the left side of that page. Start from the begin. Once you reach the 'Use It' section, follow the library install, Power Usage and Using DC motors parts of the tutorial.

really thank you very much

ok so the motor will not work at full power. I will connect the motor to signal generator. The motor will rotate, the ardunio connected to the computer power only. By using photo sensor I can find the rpm (speed).

but still I did not find a way how to read the signal generator input voltage to dc motor by ardunio , Is the any way to prevent ardunio damage.

sazan , you should not have to use a signal generator. The Arduino and Motor shield will generate the signal for the motor.

Can you make and upload a drawing of how you are going to connect the motor to the shield, and how you are going to connect your external power supply to the shield?

My advise is to really follow the adafruit guide step by step, without skipping a single point.

It contains everything: electrical connections, library install, sketch to test the motor.

Try to finish the tutorial and don't give up until you have it working. Your motor should run forwards for a second, run backwards one second, and stop for one second.

When you are at that point, you can think about next steps.

ok thank you.

Sazan, I have a suspect.

If you had spent all the time that you spent writing and expecting something to copy and paste seriously studying the problem, probably your project was already working.

Iam working on labview and iam not going to copy past. Why you say that
