What exactly is it that you want to measure. Measuring the speed of your transmision is kind of hard but measuring the speed of a bicycle wheel or a robot motor is not that hard? Before I can give an answer I have to knwo exactly what you want. Refereing to the LCD. If you are lucky you can get a leftover one from an old rado or electronic equipment. If not then it will all have to depend of what options you want on it. For example in jameco.com they sell a 1 line 16 character LCD for $13. if you want a 2 line then thats going to cost you extra. If you want graphics like bars and what not then I would recomend you buy one specifically for that purpose and its going to cost you extra. There are even ones that have 4 lines 40 characters per line. I know I'm being kind of vague here but we( I ) need to know what exactly is it you want. If is just for experimentation purposes then buy the cheapest one. a 1 line LCD or the more comon 2 line LCD. |
