Instructions

In TinkerCAD, connect a hobby gearmotor to Arduino via L$293$D chip. Connect a $9$V battery to the chip to power the motor. Also connect a distance sensor to the same Arduino. Write an Arduino code that will turn the motor on at full speed if the distance is more than $20$ inches and reverse the motor at half the full speed if the distance is less than $20$ inches.

Take screenshot$($s$)$ that clearly shows the code and the circuit at a readable zoom. level. Include screenshot$($s$)$ and a TinkerCAD link to this system, on the page$1$ of your submission pdf file. $(15$ points$)$

In TinkerCAD, connect a servomotor to Arduino. Also connect a light sefisor $($photoresistor$)$ to the same Arduino. Write an Arduino code that will turn the servo to $90$ degrees if the light $($as measured at an analog input pin$)$ is larger than $500$ and turn the servo to $0$ degrees if less than $500.$
