$1.$Investigate ARM MCU technologies used in the Arduino based platforms. Find three separate Arduino platforms that use different ARM MCUs. For example, the Arduino Nano$33$IoT uses the Cortex M$0+$and thus cannot be included in this investigation$\mathrm{.}2.$For each of the three Arduino boards, compare the different ARM MCUs used and that youhave identified based on power consumption, memory size, number of GPIO pins, number and type of timers, and number and type of peripherals supported$\mathrm{.}3.$For each of the $3$investigations$,$ comment on the suitable type of application that the platform could be used for e$.$g$.$low power, sensing$,$or robotics. Give specific exampleapplications with respect to industry problems such as agriculture$\mathrm{.}1.$Investigate ARM MCU technolo
