Finalized list of parts, ordered white diffused LED, researched ultrasonic sensors

Finished block diagram

Researched power consumption of average modern street lamp

March 2nd, 2017

Tested Diffused LED lights

Discussed logic gate requirements 

Karnaugh maps & SOP to NAND gate simplification

March 9th, 2017

Diffused white LED lights too large

Decided against ultrasonic sensors, will use buttons as pressure sensor substitute

Order soldering iron & solder
