DC motor: 3-6v Servo sg90: 3-7.2v Esp 8266 01: 3.3v
I have 2 Arduino Uno both has their own ac-dc power adapter.
Lets say, 1st Arduino is
Ard1 and 2nd is
Ard1 communicates to a web server (BLYNK) with Esp 01.
Ard1 sends command to
Ard2 to power/move the DC motor/Servo.
So far, it has no problem operating with Servo. But,
Ard1 commands the
Ard2 to power the DC motor.
Right when the DC motor runs(using
digitalWrite(motor,HIGH)) the Esp 01 resets.
analogWrite(motor, 102)though it won't reset instantly, prolong usage randomly resets it anytime.
I also tried to test operating Servo and DC motor simultaneously in
Ard2using Serial commands, without I2C/Esp01. There was no problem at all, both works flawlessly.
