chip, a heater, a fan, and a Bluetooth interface module. Draw the block diagram to show
how the system may be configured.
6. Repeat Exercise 5 by assuming that we wish to control and monitor the temperature with
our mobile phone and Wi-Fi by sending and receiving data through the Cloud. Assume
that we already have a local Wi-Fi router and a Wi-Fi interface module for our
microcontroller.
7. In Exercise 6, explain the advantage of monitoring/controlling our oven through
the Cloud.
8. Explain how the system block diagram in Exercise 5 should change if we wish to monitor
the oven temperature via SMS messages received on our mobile phone.
