I have just joined this forum in hope I can receive some guidance on how I can achieve my electronic project. I must warn you that I am a complete novice in the electronics world so if I have joined the wrong forum then please accept my apologies. On paper my requirements appear fairly straight forward but when I come to putting it into practice I haven't got a clue where to start, even down to where and how I can acquire/purchase the relevant components. To help my explanation I have attached a brief diagram to explain my requirements. The aim of my project is to create up to 8 handheld devices which on the press of a momentary switch send a unique keystroke (Alt+8 etc) wirelessly to a receiver which in turn is replicated on a laptop screen. The receiver must have the ability of receiving eight different keystroke signals at the same time. Where do I start or am I living in cloud cuckoo land? Thank you for any assistance anyone can provide Graham
