The idea
The idea of this week is an extension to the last week assignment, building a parking sensor whuch read signals from multiple input components and control multiplemultiple output actions

Using Arduino IDE, program the Arduino UNO to implement the actions needed
TINKER CAD circuit
ultrasonic sensor + Temp. sensor
Smart devise that sense the distance to help the car to park easily and maintain the temp. of the car motor
In ultrasonic part, when you are going to crash, the sensor start to send signals to the buzzer to help you stop and park easily
at the same time the RGB emit red light to tell you to stop
the second part use a temp. sensor to maintain the temp. of the motor, so you have to take care if the blue light AND the buzzer turned on.
You are Always safe, when the GREEN light is on.

Overcoming Challenges
Overcoming Challenges
After displaying the temp. sensor, the blue light remain and does not return back to the blank color (green)
but after i completed the if statement with "else" the blue light turned of after the effect of heat ended.

How can you use the skills and knowledge that you've acquired this week in your final project?
How can you use the skills and knowledge that you've acquired this week in your final project?
Start using Arduino C code to write a full code for the first is a really exciting experience, I learned how to implement the functions using writing instead of BLOCKS, which makes me get deeper with the Arduino concepts to use it on my final project
