how to make this device? Answered
hi, i want to make a device, please tell me how... there is something that looks like a tv remote . it has 9 buttons on it. And there are 9 light bulbs. when i press each button, each of the 9 light bulbs should light up. for example, when i press button 1, light bulb 1 should light up. when i press button 2 , bulb 2 should light up, button 3 turns on bulb 3, and so on. this needs to be wireless. i have done some research and i have found that i need something called an RF transmitter and RF receiver. I just need some hints on how to make this device. i hope it is clear what i want , english is not my first language, if its not clear let me know and i will clarify.
