Super Noob - PIR Sensor Controlled LED Dot Matrix

I have zero experience with microcontrollers, so sorry in advance.

I am designing a product for a school project (I think I bit off more than I can chew). The product is a mailbox that turns on an 8x8 LED dot matrix control module when a PIR motion sensor is triggered. I would like the LED matrix to stay on until a reset button is pushed. The power source will be a 9V battery. I am using the Arduino UNO.

Can both of these components be used with one microcontroller and power it by using the 9V battery power source? I don't need the light to last long, just enough for a 10 min presentation.

Any help with this topic is much appreciated.

I am willing to pay for help on this project.

Yes it is very simple.

Just get the two bits of hardware working first. Search for using the MAX7219 chip, there are a few libraries that do this. The PIR sensor is even easier, connect to power and ground and the center to a pin. Then use the push button sketch in the examples section of the IDE.

Combine the two functions by using the "if" function.

Thank you sir!
