4. A CMOS port output is modelled as shown in Figure 3.4(b). It is powered from 5V. The value of RS(high) is estimated to be 120 U and the value of RS(low) 70 U. One port pin will light an LED when it is at Logic 1, and another will light an LED when it is at Logic 0. An LED current of 4 mA is required; for this the LEDs have a forward voltage of 1.8 V. Sketch a circuit showing how each LED is connected and calculate appropriate resistor values.

Goal: To become familiar with using Port A and Port H as input ports H as an input port and port B as an output port, using dragon12-Light boards as well as to improve your programming skills.Project: Write an assembly program and a C program to do the following:When DIP switch #8 is high and #1 is low, turn on all the even numbered LEDs and let them stay on even after the switch #8 is changed to low.When DIP...
Question 4. (a) A full-wave bridge rectifier power supply is powered from the secondary of a transformer which has a rms secondary voltage of 15.6V. The primary of the transformer is connected to a 50Hz, 230VRMS power supply. A 2700uF filter capacitor is used. A current of 1.5 Amp is drawn from the supply. (i) Sketch a schematic diagram of the setup. (ii) Calculate the mean de output voltage. Assume each power diode has a forward voltage drop of 1...
(6) A blue LED with a forward voltage drop of 3.5V is to be energized from a 12 volt battery. To light the blue LED to ful brightness requires a current of 20 mA through the LED. The blue LED has a peak inverse voltage rating of 5 V. i) Draw the circuit dingram of the arrangement you will use to light the LED to full brightness. (ii What is the value of the resistor you will use in your...

I am doing an Arduino Uno project where I made a "Simon says" memory game with 3 neopixel LED strips and 3 - ultrasonics. I have them working independently but I need to combine the code so they work together. Here is what I have: Memory Game #define PLAYER_WAIT_TIME 2000 // The time allowed between button presses - 2s byte sequence[100]; // Storage for the light sequence byte curLen = 0; // Current length of the sequence byte inputCount =...
