Chapter 4 Fast Fourier Transform (FFT) (FFT) 4. 1 Introduction Fast Fourier Transform (FFT) is not a new transform, but a fast algorithm of Discrete Fourier Transform (DFT). The calculation of DFT is
Because the voltage of AD is 0 to 15V after passing through AD595, and the sampling voltage of low-power AD chip is generally in the range of 0 to 5V. So I need to find a way to reduce the voltage to
[align=left] A few years ago, I bought a GY-31 color sensor module, which uses the TCS3200 chip. This time, the topic is to use this color sensor module to make a color card password lock. Today, let'
