Just what part "doesn't work"? Can you tell us what you are trying and what is happening?

What motor are you using and what are you powering it with?

4 1.5v alkaline batteries is too high a voltage. The Crickit has an electronic fuse that shuts it down if the voltage goes above 5.5V.

See this page for a discussion of powering the Crickit: https://learn.adafruit.com/adafruit-cri ... ng-crickit
In particular, for AA battery packs, use a 3-battery pack if you're using 1.5V alkalines (3*1.v = 4.5V). Only use a 4-battery pack if you're using NiMH, which are only 1.2V.
https://learn.adafruit.com/adafruit-cri ... -packs-4-7

Quoting also from that page:
The Cricket has two LEDs to let you know how the power supply is doing. If you see the green LED next to the smiley face, you're good to go. If you see the red LED next to the warning triangle, the voltage is too high, too low or too much current is being drawn.

Boss if you focus in my picture that I have sent the light was green which mean the power is good
Also I ordered 1.2 batteries and also it does not work
Don’t talk. Let us cut to the chase are you going to replace or not

"Please be positive and constructive with your questions and comments."

Here's a zoomed-in crop of one of your pictures, with the fuse LED's showing. The triangle ("power trouble") red LED is illuminated, which is why I suspected a power issue. The smiley face green LED is off.

The Crickit processor and the micro:bit are not affected by the fuse, so the micro:bit will work and you'll see LED's at the bottom of the board working, but the motor control part of the board will not be working.

Once a power-pack of 4 1.5V alkaline batteries gets run down somewhat, and the voltages drop, its total voltage may start to be low enough to work.

Please try your friend's setup with the identical battery pack, and swap micro:bits too if necessary to check your board and theirs. See what the fuse LED's are saying.
