DIY Car Digital Thermometer with ATtiny85, Shift Register, TMP36, and LCD screen

This is a working proof of concept. With winter coming I want to know just how cold my car is and just how hot in the summer. I now need to solder it all to a PCB. I was thinking of adding a red LED that it will glow in my windshield when it reaches a comfortable temp. So I can see it from my house when I preheat my car in the winter.
