What we need to buy:
-Arduino Mega (ORDERED)
-LEDs (ORDERED 30)
-Battery -- Jen is looking into which one (order end of week 2)
-MOSFETs -- we have part number (order end of week 2)
-Resistors (order end of week 2)
-Voltage Regulators -- we have part number for 9V regulator (order end of week 2)
(Reason for ordering end of week 2 is so that we can test the circuit with Steve's equipment before we purchase anything)
What we need to look into/research:
-PWM base frequency and if we need to change it (Nick)
-Burst Duty Cycle (received more information from Pei about this later in the day)
-LED's arrangement in series vs. arranging them in parallel
-How to achieve the desired max power output of 100mW and how to measure that (borrow Pei's optical power meter)
What we need to do now:
-Individual Component Analysis
-Move our progress from google docs onto this website
-Test 3 LED array (Meeting on Monday from 12-1pm and possibly again from 5-7pm if needed)
-Write code -- Noor & Nick will work on on Sunday
- 50 Hz (with 75% duty cycle) on 6Hz
