The Arduino teaching apparatus communicates with an infrared human body induction module through Arduino and controls the turning on/off of the LED lamp based on information captured by the module, and the circuit is shown in the graph. The infrared human body induction module and the LED lamp ...
都还是从 UNO板子上开始玩，而这些板子的共性，就是都是用了 DIP（直插）28 脚封转的主芯片。

You will type text on Serial Monitor and then clickSendbutton. Arduino reads data and process it. To read data, we need to use the following Arduino code: Set baud rate and begin Serial port Serial.begin(baudrate); Check whether data is available or not ...
If NL&CR are not selected, the Arduino will still send the data but the Bluetooth Terminal program will not display it until it receives a carriage return / newline. Next step. Turning an LED on and off. Turning a LED On and Off by Bluetooth ...

介绍 旋转或编码器是一个角度测量装置. 他用作精确测量电机的旋转角度或者用来控制控制轮子（可以无限旋转，而电位器只能旋转到特定位置）。其中有一些还安装了一个可以在轴上按的按钮，就像音乐播放器的控制按钮。Some of them are also equipped with a pushbutton when you press on the axis (like the ones ...
I followed the MOSFET circuit, used the code as well but it is not working. The 24v solenoid valve is not turning ON/OFF when I pressed the button switch. What do you think is the problem? I am using a 24v power supply for the solenoid valve. The solenoid valve is working if I di...
Warning:Never turn on the internal reference while applying an external voltage to the reference pin. Before turning on the internal reference check that there is no external voltage applied. If there is it is likely you will blow something up (see the ADC block diagram below). ...
