Thanks for ur reply,
How to connect 9v battery to the microcontroller with regulator? Operating voltage of microcontroller is 3.3v.
Please explain with circuit diagram.
The power is provided using battery. If i powered microcontroller permanently, the battery will last within few hour.
Please tell me how i should design this circuit?
Which 9vbattery is long life for this circuit?
I am working on home automation system project.
In our project RF chip(microchip MRF24J40MB) is connected to the microcontroller atmel(atmega16).
RF chip is used to transmit the command from microcontroller via spi.
This whole unit is powered by battery.
If i press the switch of any bulb or fan...
How to power the RF transmitter while i have to transmit any command?
After transmit power should be OFF.
Next time when i have to send command power should be ON, Otherwise OFF.
power is given by the battery.
Note : RF chip is connected to the Microcontroller and data is send via SPI?
can...
