first of all, here we go, i post in english this time
lately i’ve been experimenting stuffs, like i’ve allways done actually.. everytime i wake up
this time i wanna tell you guys about my experiment on Infra Red Remote. I kinda create my own remote control, just for fun. I got this idea when i was asleep in my compartment then i realize that the light in my room was too bright.. somehow i want to turn it off…. but, i was very lazy to step on the cold floor and walk to reach the lamp switch on the wall. then i started to think of what possible solution to the problem i had.
first thing would be having nanny or someone to help me reaching the switch, or if i had these super telekinetic ability.. i could just think of the switch to be turned off. but unfortunately i didnt have both the solutions. in a flash of a second.. i got the thought of.. a remote control which allow me to just move my fingers a bit and just enough to reach the switch and do the turning off of the lamp.
so after a while thinking, i could use my skill of electronics and embedded system programming to solve my problem. the solution come up. i can use either radio frequency or infra red to do the wireless data transferring my needs of turning of the switch into the switch. of course with limited money i had in hand my solution have to be cheap and affordable by me yet interesting to be done. lucky for me.. as i walked around electronic shops i found an interesting InfraRed Sensor that have been very good… well made with all the ability to band pass filter the infra red signal only for a certain band of modulation frequency.. and its very very cheap.. so i decided to use this instead of RF for economical reason.. and beside it’s just enough for my needs. i need to control my lamp not from very far distance.. just 2-4 meters
and so the experiments took places.
and this is the picture of my remotely controlled lamp.
my remote control can adapt to any remote control signal from a general remote control from any brand/manufacturer as long as work with the modulation frequency of my receiver. i placed a”learn” switch for the receiver module to learn signal from remote transmitter (remember, could be any remote transmitter-from any kind of device, television set, radio/tape/CD/DV.. etc 🙂 ) as long as it operates on the modulation frequency of my receiver then my remote switch will work!
so now i can sleep tight when i forgot to switch off the lamp i just pick up my remote aim it at the lamp and put a click.. and the lamp just follow my order :)…. remotely! wirelessly!
i am now very happy
i wonder, have i actually explain it well.. at least i’ve tried…
ok.. that’s all for now.
here’s a video i recorded using my cellphone during my system test
