Design an Arduino Uno based 24VDC motor control circuit. The motor should start with the presence of a 5V signal, however it will have its own power supply. The circuit will be designed and simulated with MultiSIM. Include the following:
Engineering calculations to justify component selection.
Screenshot of the circuit constructed with MultiSIM (or equivalent circuit simulator)
Screenshot of the circuit simulation running and the measurements of the input voltage and voltage on each lead of the DC motor.
Include a discussion of the importance of electrical isolation when interfacing microcontrollers to higher voltage inductive circuits (motors). Include detail of how electrical isolation can be achieved to protect the microcontroller and motor.
Write a program to count the number of elements in an array whose bits 3, 4, and 7 are zeros. The array has N 8-bit elements and is stored in memory locations starting from $1000
Discuss how delay is generated (1) using only one register, and (2) using a pair of registers . explain the method to calculate the delay time. Describe the interface connections of a 7 -segment display, which can display alphabets as well as dig..
Consider the casual LTI system where the output relates to the input by the following differential equation: dy(t)/dt + 2y(t) = x(t) a) Determine the frequency response H(jw).
The owner wants to an addition to the building in the above question which will have a large kitchen and dining area. It will add an overall 120 kW of kitchen loads (pf = 0.95 lag). What is the new profile of the total building load in terms of P,..
1. Obtain a minimal hazard free SOP expression for f(A,B,C,D)=fm(0,1,5,6,8,11,13,14,15),d(2,3,10). 2.Implement f(A,B,C,D)=åm(0,4,5,7,10,13,14,15),d(1,2,9) using a minimal number of 1-of-2 MUXs and NOT gates (if needed).
The address field of the instruction (stored at W + 1) is designated by the symbol Y. The operand used during the execution of the instruction is stored at the effective address symbolized by Z. An index register contains the value X.
The output of a voltage follower is to be within .02% of the ideal value. What is the minimum op amp open loop gain that is required
A rectagular waveform has a 50% duty cycle (hight for 1/2 a cycle and low for 1/2 a cycle). It goes between two voltage levels of -3 V (low) and +8 V (high), and has a period of 100 μs. determine the average voltage of this waveform and the RMS vol..
plot the output voltage for problem, when the supply voltage op-amp is (+ or -) 20V. however, the voltage gain is defined as Av = (Vout / Vin). and the output of the amplifier is limited by its voltage supply.
A network connected between terminlas a and b consists of two parallel combinations that are in series. The first parallel combination is composed of a 10 OHM resistor and a 19 OHM resistor.
Draw the phasor diagrams associated with under-excited and over-excited synchronous motors and show the power factor of operation associated with each.
H(s) = ( 100 (s + 20) (s + 50) ) divided by ( ( s +8 ) ( s + 300 ) ( s + 5000 ) ) Determine the Bode magnitude and phase responses forH(s). Label all slopes and dB values.
