when i try to run the arduino through the usb cable connected to a wall usb adaptor it wont work properly but when i connect it back up to my computer it works fine anyone know why?
Please give a proper description of "wont work properly" !!
What kind of wall adapter? 12V or a USB charger or ... ?
Connected to what? Barrel or Vin or ... ?
What's all connected to your Arduino?
Bad cable or bad "wall USB adaptor".
What sort of adaptor? If it's a charger, some will cut off if there is too little current draw because they think what they're charging is full. That's more commonly a problem with power banks than mains chargers but it can happen.
