Hi,

I need help simulating my project in Proteus, problem is, I have never used it before.
This is what I have so far. However, feel free to suggest ideas that will make the circuit simpler and or more reliable.

This system will generate an alarm when a baby has been left unattended in the car.

There will be pressure sensors on both, the driver''s seat, and the baby''s car seat.

As soon as the driver is no longer making contact with the sensors two things will happen. First, a warning alarm will activate while, a counter will start counting. Once the counter reaches 60 secs (approximately) the warning alarm will turn itself off, and the main alarm will sound off.

Now, the remote part.
Once the driver is no longer making contact with the pressure sensors a link will be established between the two transceivers. One stationary say, car seat, and the other, a remote unit (key fob). Once the parent or guardian goes beyond a set range (approx. 10-15 feet?) the key fob will beep, along with the main alarm. The only way to reset the system is to remove the baby from the car seat, which will "kill" the link, or to seat back in the driver''s seat.
I can''t think of any more details that you could possibly need, but if you do, send me a message and I''ll answer within 5-10 minutes.

For this, I will use two Arduino UNO with ATMEGA328P-PU, each with its own transceiver "NRF24L01"
However the transceivers are not listed in the library, so any equivalent will do. Don''t know if a wireless transmission can be simulated in ISIS, if anything, just wire it
