Dear Pi users,
I am a teacher, teaching in what used to be a warehouse, that is full of pillars that block my students' view of our projector image. Students are constantly having to move all around just to see what is being presented. One thing that is on each of their desks is a Raspberry Pi 4 connected to a monitor. Is there some way for me to have what I am presenting on the board show up on their screens? The projector is currently hooked up to my Samsung A Tablet via bluetooth. I am trying to think of some outside the box solution to have what I write on the Samsung A Tablet end up being visible not only on the projector board but also on each of the monitors connected to the Raspberry Pi 4's at each of the students' desks.
