(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...
Please answer the problem below for all parts. Please show all work and write clearly. Thanks. The circuit below is a temperature range indicator using a Window Comparator circuit. Discuss when you would use this type of analog circuit and when you would use a microcontroller based circuit like that of Lab 4 shown below. A window comparator usually employs 2 comparators with one output indicating the input is somewhere between two limits. In these examples, a third comparator is...

6. LED Alarm Circuit One day, you come back to your dorm to find that your favorite candy has been stolen. Determined to catch the perpetrator red-handed, you decide to put the candy inside a kitchen drawer. Using the following circuit design, you would like to turn on a light-emitting diode (LED) "alarm" if the kitchen drawer is opened. Rli LED 2.5V LED Note Rphoto is a photoresistor, which acts like a typical resistor but changes resistance based on the...
