slightly faster. The best known of this new line of chips (among hobbyists, at least) is the ATmega4809, used on the Arduino Uno WiFi Rev.2 and Nano Every. However, there is also an extensive line of tinyAVR parts based on this new architecture, ranging from 8-pin to 24 pin ...
模拟IO口读函数,从指定的模拟接口读取值,Arduino对该模拟值进行10-bit的数字转换,这个方法将输入的0-5电压值转换为 0到1023间的整数值。pin表示为0～5(Arduino Diecimila为0～5,Arduino nano为0～7)。即“analogRead(接口名称)”,比如可以读模拟传感器(10位AD,0～5V表示为0～1023)。
int analogRead(pin) 模拟IO口读函数,pin表示为0～5(Arduino Diecimila为0～5,Arduino nano为0～7)。比如可以读模拟传感器(10位AD,0～5V表示为0～1023)。 analogWrite(pin, value) - PWM 数字IO口PWM输出函数,Arduino数字IO口标注了PWM的IO口可使用该函数,pin表示3, 5, 6, 9, 10, 11,value表示为0～25...

代码主要使用了TIMER1定时器。需要计算发送到电机的脉冲频率。用的Arduino NANO 主频是26MHz, 普通42步进电机的步距角是1.8度,转一圈都要200个脉冲,A4988芯片最大可使用的细分是16细分,如果用16细分,转一圈都要20016=3200个脉冲。我的目标是每三分钟转100转,需要的脉冲频率是1003200/(3*60)=1777.77Hz ...
Instead of messing with the wiring, [Marco] took the non-invasive approach and is using a DIY coil to detect the magnetic field of the espresso machine’s pump and start a shot timer. An LM358-based op-amp magnifies the current induced by the machine and feeds it to an Arduino Nano,...
