We met with Garth earlier today and were able to transfer data back and forth to eachother through MQTT! We updated the code, to take account of the data being processed into the command, as well as adjusting the collaboration of the sensor pad. Our next goal is to incorporate another sensor pad so we can control speed along with the direction of the puppets. We have also made plans to come together and assemble the environment that the puppets will be in. We would like to invite other students visit our puppet show this weekend if they would like to participate!<\/p>\n\n\n
