Hello everyone, I'm a small-story.Remember the previous section click the Open linkToday we talk about sensors.Today, we talk about light and ultrasound.Send a picture first:The light sense has three interfaces, namely:UCC, out, GND.The ultrasound

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

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

Using JavaScript to manipulate hardware has long been a rarity. So as an electronic professional origin of Fe, I also intend to try to use JS to drive Arduino; To operate these underlying hardware, there must be some tools, and the tools I'm introducing here are mainly Cylonjs and Gort. Cylonjs is actually a operation "machine" JS framework, the official website of the introduction is such: Cylon.js is a JavaScript framework for robotics, physical

development. Although our open-source list usually focuses on software, this list also contains some open-source hardware, most of which are offered to IOT enthusiasts at a low price. As usual, If you think some projects should appear on our list, please don't hesitate to give us some advice and write these projects in the comments section below. Development Tools 1.

6th Section MotorTo say Bluetooth car which module is most important, most people will think it is a motor.Previously said, in order to prevent the Development Board by the current breakdown, the control motor to add a piece of expansion board.Therefore, the control motor, only the expansion board programming, and do not need to program the motor.In addition, the expansion board manufacturers will provide code to control the motor through the expansion board.In summary, for the developer, the mo

the internet of things and standards has largely emerged in the open source community. We will introduce some of the more interesting open source networking projects that are currently being actively developed. Although our list of open source projects is usually focused on software, it also introduces a large number of open source hardware, and amateurs can buy many of them at low prices. As always, if you think other items should be on the list, you are welcome to exchange messages. developme
