When Qbot doesn’t have enough power supply, it will make a sound like” DiDiDi.”
When you hear that, the battery should be taken out and put into a special charger to
charge at least two hours.
Q5: Why does the .sb2 file fail to read?
A: If your Makecode display “Fail to upload,” This prompt means that you do not
select the control panel type. You should choose Qbot in the control panel, or
reconnect the USB port first.
Q6. Why can’t LED light turn on?
A: First, please check whether the Qbot power switch has turned on, and second
check whether Qbot has enough power supply.
