The motor in the following circuit is driven from a buffer that is controlled by an Arduino. Complete the design of the circuit so that the buffer (which is more than adequate to drive the motor\'s current and voltage requirements) will not be negatively affected from effects of controlling the motor.

Solution

By using temperature sensor LM35 with an arduino kit to control a motor and change its speed with respect to the temperature read by the micro-controller(arduino kit).The temperature sensor LM35 is connected with the arduino with an analog input pin A0 (the temperature is an analog signal), while the motor is connected with a PWM (Pulse Width Modulation) pin 6 which controls the speed of the motor with respect to the output temperature using a function map in the arduino IDE(Integrated development Environment).
