Write a sketch for the Arduino Uno such that it will generate the PWM output on pin 9 with respect to the voltage read on AN5(see the illustration below). The Arduino Uno will be using an external voltage source of 5V as its reference voltage for the ADC. AN5 Pin9 1.25V 100% 2.5 V 50% 3.75V 25% 5.0 V 0% Output waveform

Step 1
First, we need to set up the ADC (Analog to Digital Converter) to read the voltage on AN5. We will use the built-in ADC of the Arduino Uno. Show more…

Design an opamp circuit to perform the following operation: 5A(t) + 2 on the analog signal A(t). Assume that the opamp is powered using a 3.3V power supply. Also, assume that A(t) can take any value in the range: -0.1V to 0.2V. You can use only one opamp and any number of resistors.

Sketch the diagram of a circuit that contains a $5-\Omega$ resistor, a $10-V$ voltage source, and a voltage-controlled voltage source having a gain constant of $0.5 \mathrm{V} / \mathrm{V}$, Assume that the voltage across the resistor is the control voltage for the controlled source. Place all three elements in series. Several answers are possible, depending on the polarities chosen for the sources and the control voltage.
Draw the circuit diagram of an op-amp voltage follower. What value is its voltage gain? Input impedance? Output impedance?
