Due to the bootloader, it can download programs directly through USB. The image of the ATmega328 is shown in Fig. 17.5. It is designed to transmit the detected signals to the Arduino controller to process, and the Arduino uno controller sends those signals out again (Kumar et al., 2016)...

In the image above, you can see the entirepin mappingof the Arduino Uno, the port numbers are in the yellow fields next to the pins. (image credit) Since every bit of the byte represents one pin, it is easier to write the values inbinary notation. You can do this by adding a capit...

我们在 Arduino UNO 中有 1023 字节的内存,其中我们有 1018 字节来存储数据,我们已经在 30 天内获取了 5 个用户出勤数据。每次出席都会记录时间和日期,因此这将成为 7 字节的数据。 所以所需的总内存是 5307=1050,所以这里我们需要更多的32字节 但是如果我们要使用 4 个用户,那么我们需要 ...
