Begin with a breadboard, wire, an RGB LED and some resistors. Using the forward voltages given in the RGB LED datasheet, calculate the correct current-limiting resistors needed to light each color of the LED (assuming VDD = +5V). Using a power supply, test that each color of the RGB LED is working correctly with these resistors.
Next attach a NI USB-6008 (or USB-6009) to the computer. And attach breadboard wires to the analog outputs AO0 to AO1, a wire to a digital output and another wire to a common ground
Create a new VI that creates a flashing control, where the LED will have a 50% duty cycle. The user should be able to set the frequency between 0 and 10Hz.
Create a PWM controller for intensity. Hint: use a for loop with a case structure inside. And use a wait timer to control the speed. Allow the user to adjust the frequency and duty cycle.
Create a new VI with a "lighthouse" control to the front panel. When the user selects "lighthouse" the light intensity rises to a cusp and then falls in a similar way (see the short video posted on D2L.) Note that the rise and fall in intensity is not linear. What trig functions should be used?
A circular coil of 200 turns of radius a=60mm, total resistance R=2 ohm, and no self inductance is rotated about a vertical diameter with uniform angular velocity =200 rad/s in a horizontal magnetic flux B of 0.25 Tesla.
Draw the power supply current as a function of the input voltage for a CMOS inverter. What is the current when the input is at VOH. What transistor causes this. What is the current when the input is at VOL.
a sample of 0 385 gram of cus was formed by heating a mixture containing 0.318 gram of copper and 1.00 gram of sulfure according to the reaction , Cu + S ---> CuS. A) is copper or sulfer the limiting reactant B) calculate the theoretical and the pe..
Write a script that determines whether an amino acid is going to bind to a certain molecule. It is know that the first region (1-5) of the molecule binds strongly to amino acids A, C, I, L, Y and E, and weakly to W, S, M, G, and K.
A three-phase, 2000-kVA, 12-kV, 1800-rpm synchronous generator has a synchronous reactance of 20 ohms per phase and negligible armature resistance.a. The field current is adjusted to obtain the rated terminal voltage at open circuit.
A load consists of a resistance R in parallel with a capacitor of reactance X. The load is fed from a single phase supply through a line of impedance 8.4 + j11.2 ohms. The rms voltage at the load terminal is 1200 at 0 degress V rms,
First draw the transmit con-stellation and the receive constellation with ideal phase tracking and sampling. Note:they are obviously the same constellations. Now, assume that receiver synchronization is off by a phase angle.
Assume that life on Mars requires cell potential to be +100mV, and the extracellular concentrations of the three major species are following (mmol/L): Na+ : 145; K+ : 4; Cl- : 120. Choose one species and assume that other two permeabilities are ze..
An AC signal has a peak value of 100 V and a frequency of 60 Hz. If the voltage crosses zero in a rising direction at t=0 seconds, what is the instantaneous voltage at t = 0.004167
A parallel-plate capacitor is charged to a potential V0, charge Q0 and then disconnected from the battery. The separation of the plates is then halved. What happens to (a) the charge on the plates
Find out the birthday (month and day but not year) of a randomly chosen person. What is the sample space of the experiment. How many outcomes are in the event that the person is born in July
Design a current divider that will provide a 1/3-2/3 current splitting ratio. Use resistance in kilo ohm range. Redesign the current divider so that the resistors are less than 100 ohms but maintain the same 1/3-2/3 splitting ratio.
