    I am doing a project using pic16f873 microcontroller to control the dc motor by using Lm293 Ic by using bit 1 or 0 to make it turn left or right. The problem i having now is i need a interface as a input (eg, Ird or ultravoice ) but not switch.

    May the masters here can help me by giving me a simple interface input circuit or ideas so that i can finish this project.

    Thx you for reading.
