INPUT FOR LOADS
A=load1
B=load2
C=load3
S=ALL OFF (LOAD1=OFF,LOAD2=OFF,LOAD3=OFF)
N=ALL ON (LOAD1=100%, LOAD2=100%,
LOAD3=100%)
Example
A100= load1 at 100% dimmer level.
A026=load1 at 26% dimmer level.
B065=load2 at 65% dimmer level.
C089=load3 at 89% dimmer level.

CONNECTING WITH PIC PROJECT BOARD
CONNECTION DIAGRAM
WORKING
- Make the connections as shown in diagram
- Connect PC and USB to TTL through USB cable
- Connect TX pin of Dimmer to RX of USB to TTL
- Connect RX pin of Dimmer to TX of USB to TTL
- Connect bulb to the Load 1
- Connect AC IN of Dimmer to power supply

NOTE: Since this module working with live 230V AC, while experimenting
user has to take proper safety precautions.
