Answer the questions about the Arduino board What is the pow

Answer the questions about the Arduino board. What is the power supply voltage used in the Arduino UNO R3 board? (the schematic file for Arduino at the following link, . Uno Rey3r.schematic.pdf.) Determine the maximum LOW level input/output voltage and minimum HIGH level input/output voltage according to the given electrical characteristics. (You may refer to the data sheet of ATmega328P) Please find the contents of PORTC after execution of each line of the following codes (assume the code is executed in sequence): PORTC = 0 times 73 & 0 times CA; PORTC |=0 times 99: PORTC = -PORTC: PORTC = -(0

Solution

1.

a)5V power supply voltage used in the Arduino UNO R3 board. The board can be supplied with power either from the

DC power jack .Use of voltage should be in some limits and order.
