[Arduino] 1. Use lcd12864 to display the temperature value read from 18b20

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

Arduino example-optical control + PWM analog output

  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

Arduino-Human Infrared sensor (PIR) module hc-sr501

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

Decoding analysis and simulation of 315MHZ and 433Mhz wireless remote control signals

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

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

Nodejs Simple Implementation Operation Arduino_node.js

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
