III. Theory/ Discussion 1) Arduino IDE consists of 2 functions. What are they? a) else () and loop () b) Setup () and build () c) Setup () and loop () d) Setup () and elseif () 2) When forward biased, LED emits light because of Recombination of carriers and Light produced by collisions. 3) ATmega328p microprocessor is used in arduino UNO. (TRUE/FALSE) (TRUE/FALSE) IV. Circuit Diagram (Before Simulation) Draw the circuit and write the program codes by considering input pin as A2 and output and output pin as 9 for green, 10 for yellow LED & 11 for red LED. Also verify the results if (gas >= 100) red LED should glow, if (gas >= 60) yellow LED should glow, otherwise green LED should glow. V. Connection Diagram and Results after simulation hp

Answer the following questions. Be prolific in your answers.

I have one question left. If ever please answer this three question? *Design a decoder that recognizes the decimal number 23. * Design an encoder circuit to generate the 3-bit binary gray code. Use positive NAND/Negative OR circuit. *What is the decimal equivalent of the state being decoded by the circuit in the figure.

•An ISP is granted a block of addresses starting with 190.100.0.0/16. The ISP needs to distribute these addresses to two groups of customers as follows: •The first group has 64 customers; each needs 128 IP addresses. •The third group has 128 customers; each needs 64 IP addresses. • Write at least the first and last IP addresses for the first two and last two customers in each group.

Suppose that we have an unusual type of FET for which iD=3vGS3+0.1vDS Here, iD is in mA, vGS is in volts, and vDS is in volts. Determine the values of gm and rd for a Q point of VGSQ=1 V and VDSQ = 10 V.

This is a practice question (not a graded assignment) from my Digital Systems lab course. The first part was to create a schematic from 2:4 decoder truth table using only NAND gates. This was done, as you can see, and is correct. Now, we're supposed to write the VHDL code for a module named "2x4_Decoder" that implements the NAND gate schematic using gate terminology and the labels from the schematic, as well as a test bench for it. I'm completely lost. All we've done so far is simple individual gates, nothing with multiple gates or connections (it's our second week in VHDL). If I could see a complete, working example for this, I could probably figure out other implementation configurations. Thank you for your assistance.
