Multiple Switches with Single PIC Input

There are many techniques to implement multiple switches into PIC microcontroller.This technique requires only one ADC pin to detect voltage level when each switch for each state is pressed and each switch is associated with a voltage. For example : If we need to connect 16 switches with 10 bit PIC.

Build your own LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and "Zero Out" function to make sure the readings are as accurate as possible ... [more]
