Please see inside, because how you make the EV3 work is you place code under the define block because if you didn’t know whatever you place on the Define block it carries to the block that block thats defining it but first you got to put the EV3 in the backpack so you can use it taking it out and if you don’t know how to use the backpack, there is something at the bottom that says backpack and you drag the EV3 to the backpack
How I got this idea is there is something when coding and you press the thing that has a block and a plus on it and something would say saying Lego, EV3 but I don’t have Bluetooth but make sure you are using broadcast
