Hello I need help making the code on Arduino as I'm struggling to make the slave code for the Arduino and for the SSD screen

NOTE I can not use the library I am only allowed to use the library and the so can you make the code only using the two libraries allowed please.

Using two Arduinos, one IR module, one IR remote, one 4-digit seven segment display (SSD) create an LED light controller. This system will use two different communication protocols: SPI and IR. Your system must be able to turn on and off four different LEDs. The master Arduino will receive data from the remote using IR. The data will be decoded to turn on a specific LED or turn all of them off. Besides this, the master Arduino will transmit a code to the slave Arduino that will make it display in the SSD the enabled LED. If the LEDs are shut off, the SSD must clear itself as well. For the solution your team must use the libraries provided only.
