Can you build your own infra red timer ?

Is it possible to make a home made infra red timer from electric store supplies and enough electricity knowledge ?

I mean… If an infra can set up an alarm… why can’t it set up a stop watch ?

Of course you could. If you get stuck you could always contact Dr Emmett Brown :stuck_out_tongue:

Of course you can. But is it sensible to do so? How much time, labor, and parts will it take to effectively duplicate what you can buy?
