Me TFT LCD Screen 2.2 Inch On mBot

#1

Hi,
I plugged a TFT Screen on my mBot. I program it with Arduino. It’s running correctly.
But only if I plug my robot on the USB plug of the computer.
When the robot is unplug, it’s not start up. no thing happen. It’s look like than there is not enough power with 4 batteries of 1.5 V.
Do you have an idea ?

Silly question, but mBot has a power switch on the board, is it on?

#3

Yes, it’s on.
When I startup the mBot (plug on USB) the TFT screen start up also ( the name of MakeBlock multicolor happen ) and few seconde later, I can read the informations send by the mBot.
Without plugging USB, the Start up message (MakeBlock) not come.

@LHE1071,

I do not have a problem running the TFT on the mBot. However, it is the only thing that I am running. The current draw may be too much, if you are running motors, ultrasonic, line follower, etc. Make sure that the batteries are good.
