Topic: Can the slider be used to enter keystrokes? (Read 1 time) previous topic - next topic


Hi Esplorers,

Does anyone know if the slider can be read to send a letter 'A' for example, by moving it from full left to full right and back again? Or is it not precise in that way?

Thank you folks.



I don't see why not but why do you want to do such a thing?

Read the slider voltage and when it makes a transition from below 512 to above 512 send the letter. Remember it is the transition you are looking for not the reading now. Therefore you store the last analogue reading in a variable and the if statement says if the current reading is greater than 512 and the last reading was less than 512 then send your letter.
