For this lamp: replace an existing 50W halogen lamp with two different colors of LED.

Project hardware “requirements”:

• MSP430 micro
• Rotary encoder
• 2 LED color bins selected by MOSFET, 2 LED in series per color
• TPS92200 LED Driver

Project software “requirements”:

• PWM 5-95% set by encoder
• Soft ON/OFF using encoder button
• Long press of encoder button selects between LED Colors
• Remember last brightness setting (soft off)
• Default 50% PWM after power failure
