电池输入：0-5V(max) – 无反极性 恒流负载：37mA 至 540mA(max) – 16 步 – 可由用户修改 ...
最后,通过增加负载,Arduino nano会将负载数据以数字格式提供给DAC,DAC将模拟数据提供给运放,运放根据运放的输入电压控制MOSFET 。 最后,根据流过分流电阻的负载电流,会出现一个电压降,该电压降将被 LM358 的第二通道进一步放大,并由 Arduino nano 得到。这将显示在字符显示屏上。当用户按下减少按钮时,也会发生同样...
If you are on a tight budget you can explore the Chinese alternative Arduino Nano Every which will cost you a max of 5 USD. You will hardly notice any difference between the official Nano Every and the one you got from the Chinese manufacturers. Conclusion The Arduino Nano Every is the up...
Except ESP8266 module all the others can be run by 5V power supply.The ES8266 module need power not more than 3.7V. It is recommended to run it on 3.3V. Though Arduino Nano have 3.3V pin but it can not provide sufficient power ( around 200mA to 300mA) to run the ESP8266 module....

Only protect the expensive electronics such as Nano, IMU and pixels. In this case we can use pretty much any P-MOSFET available as it would only need to supply up to 300mA of current at max. For now I though we could at least protect the main electronics, which will make life a bit...

步进电机是一种将电脉冲转化为角位移的执行机构。当步进电机的驱动器接收到一个脉冲信号，它就驱动步进...
PORTD是一个内置的常数,是指0,1,2,3,4,5,6,7数字引脚的输出状态。如果某一位为1,着对应管脚为HIGH。(此引脚需要先用pinMode()命令设置为输出)因此如果我们这样写,PORTD=B00110001;则引脚2、3、7状态为HIGH。这里有个小陷阱,我们可能同时更改了引脚0、1的状态,引脚0、1是Arduino串行通信端口,因此我们可能...
TheExposure Boxwhich was made from a recycled components box, had it’s top lined with LED strips that are turned “on” or “off” by an Arduino Nano based control system. The control system makes use of time duration, preset by the user via a potentiometer, as the control variable. ...
