However, IoT Cloud is less preferable than Firebase, because with IoT Cloud you can't store data and have to use their GUI. </li> </p> <h3>Assignment: </h3> <p> Work with a partner or in a small group. Control a microcontroller remotely, using WiFi or radio. </p> <h3> Examples: </h3> <p> <a href='https://ctian5136.github.io/ps70/html/weeks/week9.html'>Cindy, Lane and Bobby's Rubberband Shooter</a><br> <a href='https://rebeccabrand.github.io/ps-70-fall-22/week-9.html'>Rebecca's IOT Syringe</a><br> <a href='https://michelleyl78.github.io/PHYS_S-12/09_class/09_class.html'>Michelle's Firebase alarm clock (with API clock)</a><br> <a href='https://wujibi123.github.io/PHYS_S-12/09_Networking/index.html'>Dan's multi-sensor database</a><br> <a href='https://tomkinsc.github.io/harvard-ps70/2020-04-14/'>Chris's Smart Freezer</a><br> </p> <h3> Labs: </h3> <p> Work on networking assignment.
