I want to measure the ratio of the capacitance of two capacitors. For example, C1=100uF, C2=22uF, and the output voltage value must be 100/22=4.55V. The capacitance range is 1uF~220uF, and it is imple
Microcontroller programming software has many applications in actual projects. Each microcontroller programming software and even different versions of microcontroller programming software have their
