I am new to Arduino.
I have started my small projects and trying to learn more in the COVID time.
I did buy 10 small DC motor which I guess suffice the purpose: https://www.amazon.de/gp/product/B07FM8J9WP.
At first, I wanted to simply connect it to my 11.1V battery through the Mosfet module(https://www.amazon.de/gp/product/B07VRCXGFY) and control the V-in to DC motor by the PWM pin(P9), but I realized even with the analogWrite(9, 5) still my output voltage is around 5V(again used Mosfet module).
Does the MOSFET module have a problem? It is weird, right?
Then I thought perhaps I can feed it with the 5V pin of Arduino, which I have tried but saw smoke coming out of it. Later checked the Arduino and I guess the Mosfet behind the Arduino looks like it burned.
Also, I was thinking to use the 5V output of the L298N for these DC motors. Is it a good idea?
- Battery: 11.1V 1500mh
- Arduino Nano
- The project: trying to build a robot vacuum cleaner. The chassis is built manually with Plexy, Wood, Plastic and etc.
- For the robot wheel, I am also using 2 gear motor with wheel, and L298N H bridge. It was simple to use.
