ALD Q1 Using light Depending Resistor, LDR with ardauino UNO to chick the light, write the codes? Problem You want to detect changes in light levels. You may want to detect a change when something passes in front of a light detector or to measure the light level-for example, detecting when a room is getting too dark.

Take a look at the attached screenshot. Then, explain in your own words what would happen to the circuit if the below were to be adjusted: a) Frequencyb) Amplitudec) DC Offsetd) Time per Division Then, 2. Explain in words what would happen to the LED in the circuit for each of these adjustments.

Apply 5B: Use a 7-Segment Decoder to Drive a 7-Segment Display 1. Draw the wiring diagram of the 74LS47 device driving the common-anode 7-segment display through 3300 resistors in series, one per segment. 2. Build the circuit based on the wiring diagram. Tie off any control inputs of the 74LS47 device to enable it as a 7-segment decoder. Test all the segments of the display by temporarily connecting LT (pin 3 of 74LS47) to GND. Then connect D, C, B, and A of the 74LS47 device to power or ground rail and cycle through the 16 combinations to verify that the display shows the characters according to the truth table of the 74LS47 device. 3. Now interface the circuit in Apply 5A.4 with the circuit in Apply 5A.2 such that the display only shows the numbers controlled by N3N₂N₁No that are prime. When the numbers are non-prime, the display should be blank. Hint: use a single device with basic gates.
