dc.description.abstract | A lamp controller and fun by using a microcontroller ATMega 32 have been
designed. This device is consists of a keypad as a controller, LCD displays
messages from the transmitter, the lights and the fan will be controlled and Radio
Frequency used as a data communications with far distance. Software on the
device using the programming language Cod Vision AVR. The working principle
of this tool is to use radio waves to control lights and fans at a distance, at the
transmitter (remote) consists of a 4x4 matrix keypad, microcontroller and 315Mhz
frequency bands. of keypad data will be sent to the transmitter with a wireless
(cordless). Then the data is received and processed receiver then compared with
the data that has been determined in the program as control. In this tool, if the
transmitter in press 1 then the fan will be live at 25%, in press 2 fans live at 50%,
pressured 3 fans live at the speed of 75%, and when pressed four fans will be
living with a rate of 100%. To turn on the lights, pressed the 5 lights will be lit
with the light of 25%, pressed 6 explained 50%, reduced 7 explained 75% and if
pressed 8 lights will flash with a bright maximum of 100%. To turn off the lights
pressed B, turn off fans pressed C and turn off lights and fans pressed 0. | en_US |
