discovery board stm32

Experiment 1: ADC module function
The ADC module converts the analog voltage signal into a digital signal that the CPU can process. The STM32F103RCT6 development board is used with an ADC module and a potentiometer to collect voltage. When the potentiometer is rotated, the voltage changes accordingly, and the ADC module displays the changed voltage in the form of a waveform and turns it into a digital signal that we can understand.

Experiment 2: Temperature and Humidity Module Function
The Humiture APP can be used to display detected temperature and humidity data. The stm32f103 minimum development board is connected to a DS18B20 temperature sensor or a DHT11 temperature and humidity sensor, which can detect temperature and humidity data. Temperature and humidity sensor to be purchased separately

Experiment 3: RTC clock function
The Clock APP uses the RTC function of the stm32f103 minimum development board. You need to put a button battery into the battery holder on the STM32F103RCT6 development board. The RTC clock of the STM32F103RCT6 development board will continue to run after the main power supply is cut off. Turn on the Clock next time. You will see the update time in the APP. (The battery holder is below the LCD screen, the battery model is: CR1220)

Experiment 4: Mobile phone communication function
PHONE is a phone dialing application. The STM32F103 development board schematic (STM32F103RCT6 ) can be used with an external GSM module (requires access to a SIM card) to realize the mobile phone communication function. The wiring method is shown in the figure below (the GSM module needs to be purchased separately, click to view)
