A potentiometer is also connected, with center pin connected to PA1 analog input (ADC) of STM32F10C8, Left Pin connected to GND and right most pin connected to 3.3V of STM32F103C8. In this tutorial we ...

However, when the microcontroller has an analog-to-digital converter (ADC) peripheral and an analog input pin to spare, then that is all you need. Sounds incredible, right? Yet it is very easy to do.

Relay Digital Input (P1_5, GPIO1 [8]) to Output (P1_6, GPIO1 [9]). In the 5 seconds period after board power up or reset, threshold will be auto-adjusted according to the range of the analog input ...

During the sampling process, the ADC’s analog input pin (trace 1) demands varying amounts of charge, depending on the amplitude of the input signal and the results of the previous conversion.

Libaries, wiring, and example code for various inputs / outputs for Arduino and other microprocessors When you need more inputs/outputs for your Arduino project, the response in some forums is "Use a ...
