Most - if not all - STM32 MCUs have a number of on-chip ADCs which can be used to measure analogue voltages.
For this example, we are going to be using a so-called Black Pill board. The Black Pill board is using a STM32F411 and according to the datasheet that MCU has got one 12-bit ADC with up to 16 channels.
