Instructions to connect Wemos to MicroBlocks

To connect the Wemos device to the the MicroBlocks platfrom, it must first be flashed with the right firmware using esptool.

Follow the instructions on the bottom of this page using the vm.ino.nodemcu.bin file found in this repo.

Once the firmware is on the board, you should be able to plug it in, and it will automatically connect to microblocks when the app is open
