solve this as the question needs and all parts

a. The photoresistor in the circuit to the right has a resistance of 15k when it is exposed to the light. What will be the reading of A1 (i.e, the value of x ). b. An LED will be connected to pin 9 of Arduino Uno board. As the exposed light on the photoresistor, the brightness of the LED changes as per the following codes. I/ Code 2 for Question 1 b. void setup0 f pinMode(9,OUTPUT); ) void loop 0\{ int B=analogRead(A1); int W=map(B,800,130,240,63) 3 What should be the reading at Al to produce a brightness of the LED equivalent to 200 ? What should the LED's brightness be if the reading at A1 is 470 ? And write the code to assign this brightness value to the LED
