I am trying to control a 12V DC motor using a Particle Argon, powered by a 3.7V LiPo. To get 12V I am using this step up regulator, and to control the motor I am using this DC motor controller. I am also using the Particle Argon as my microcontroller with a typical 3.7V LiPo battery
I am able to control the motor at a lower voltage by dropping the duty cycle at the PWM pin, but when running (particular when changing direction or starting the motor), the Particle Argon resets.
I am assuming that the current surge required when powering the motor is causing the voltage at the microcontroller to momentary drop, thus resetting it. Any thoughts? Is there a better approach to accomplish this? Maybe a capacitor anywhere is the circuit to solve this problem?
Any insight would be GREATLY appreciated.
