在使用delay()或者delayMicroseconds()的时候,很多事情都干不成了,所以换成普通的自制软件延时可以腾出timer0功能做些别的事情。 在做Arduino项目定时器计数器的不够用的情况下,例如:小车有四个独立直流电机,用timer1和timer2来控制 4 路 PWM 波输出,于是就只剩下timer0了。 但是timer0被利用在了delay()和delayM...

In this Arduino Tutorial we will learn how to use the DS3231 Real Time Clock Module. The DS3231 is a low-cost, highly accurate Real Time Clock which can maintain hours, minutes and seconds, as well as, day, month and year information. Also, it has automa
