Human infrared module is very simple, is the normal three-pin (vcc,gnd,data), the data is high, low level, that is, there are only two results: High level for the active body is detected, low level for no active human detection. It is important to

I wrote it here, but it hasn't been tested yet. 1. Move the two ends of the led to the center and return to the two sides. 1 // adr301.ino 2 3 byte ledPin[] = {4, 5, 6, 7, 8, 9, 10, 11, 12, 13}; 4 int ledDelay(65); 5 int direction = 1; 6 int

The board we got two days ago. The first test is 18b20, but the value cannot be read. At first, I directly connected the analog port. Later I realized that this was not a simulated sensor, but a number. It is switched to a digital port. analog

  Connect as shown in the following figure:   The resistor size of the photosensitive resistor is inversely proportional to the brightness. By measuring the voltage of the resistor, you can know the resistor size of the photosensitive resistor to

In the past SCM programming process, probably most people are more familiar with the MCU WiFi module and the server to establish a socket connection. However, it may be a better option to establish an HTTP connection when we are confronted with the

After a reincarnation, hardware development and hardware entrepreneurship were pushed to the front-end of history. For low-end and elementary hardware enthusiasts, open-source hardware with the core of Arduino and 81 single-chip development boards is becoming increasingly popular. More and more people are involved, and related hardware and peripheral modules are getting cheaper. In addition, with the creation of various maker spaces, a hardware module

data to the channel, and the other device can receive the data in the channel. Of course, for the establishment of this channel connection is a certain condition, that is, the Bluetooth set up to be able to connect the at mode0x0:softwareserial LibraryThe existing Arduino hardware supports pin 0 and 1 (connected to the computer via USB) for serial communication. The serial is carried out via a hardware called UART (chip built-in). This hardware allow

SummaryWhile learning about the radio, I learned that Arduino was a good choice for my next Raspberry Pi as a skill not yet mature technology. So spent 200 yuan to buy 3 pieces of Arduino Development Board (2*NANO1*UNO) and other sensors, but also see the 315M Super-regeneration module, because play radio know 315M is the car remote control, anti-theft gate, road and bridge system, such as the most commonly
