#	Part	Qty	What it does
1	Main Control Board	1×	MCU-based PCB running firmware to sequence motor, heater, and pump timing.
2	Mode Button	1×	Momentary switch selecting standard soy milk, smoothie, or soup mode.
3	Start Button	1×	Momentary switch beginning the selected program cycle.
4	LCD Display	1×	2-line 16-character LCD showing mode and elapsed time.
5	Led Indicator	2×	Status lights
6	Relay	3×	Electromechanical switch in which a small coil current closes or opens contacts rated for a much larger load, isolating control circuits from what they switch.
7	Microcontroller	1×	Single-chip microcontroller combining a processor core, flash memory, RAM, and peripherals such as timers, ADCs, and serial ports to run the device's control firmware.
