First, I have to mention that I am an artist and not an electronist. So my knowledge is limited in some directions of electronics.
I need a very basic (with minimum of components), very short range (~3 meters), (Like a remote control) emitor and it's receiver.
-It should not be with visible light since the entire panel is in direct light already both from natural and artificial light.
-I don't have IR Led's in stock. So it has to be with a coil of some sort.
-Ideally built with components that you have in stock ,the usual ones, and not very new or fancy that I have to wait 2 to 8 months to arrive.
A - Basic as to command a transistor that will command - a relay @5V /40mA /128R for the coil.
B - Basic as to command a transistor that will command - 5V to input pin5 for a LM3914.
Im not decided yet, and I might try both until I will decide which I will leave it as final.
This is just another module, for a bigger project im into.
Thank you for your immense help so far and happy holidays and happy new year 2021 !!!
