Home TV, air-conditioning appliances are infrared remote control, This experiment is to see the principle of its reception and emission. So two blocks of Arduino Uno are required to receive launch separately. The reception of the Arduino Uno Infrared remote control (in this article) Next, Arduino Uno Infrared remote control receiving and transmitting signal exp

ReasonThere are a number of tutorials on the network that allow the Arduino 5V level to be converted to 3.3V levels, and to communicate with the chips working in 3.3V. But if you want to drive a chip above 5V, you can't find the tutorial. So today I'm going to introduce a way to get Arduino's output port to drive an electronic component that needs 5~12v input. The following is an example of 12V.Effect The ability to achieve one-way (from

2.1 Obtaining schematics and PCB boardsLearning Arduino necessarily need to have an Arduino board, either buy or make their own, because the Arduino website provides each type of schematic and PCB, so the production is very convenient. The following is the production of our Arduino UNO Compatibility board Sagoo Uno. We

Raspberry Pi power supply to the Aruduino, through the PL2303 chip USB to TTL serial communication. The temperature of the greenhouse is detected and heated if it is below 19 degrees. The switch heating of the ceramic heating lamp is turned on by the serial control Arduino,arduino control relay. The code for Arduino is as follows: void Setup () { Pinmode (3, OU

First, preface:In the above, the author systematically expounds the two driving modes of 1602, and simply mentions the Liquidcrystal Library of Arduino. In this article, the following two questions are explored in more depth: how can I minimize the 1602-to-Arduino port footprint? How should the Liquidcrystal library learn? Under the Arduino LCD1602 Comprehensive

The article once introduced how to use the RF module to implement wireless control over Arduino. Its principle is very similar to that of remote control, which can implement RF wireless remote control with four buttons. HoweverThis solution is not suitable for data transmission scenarios. For example, you need to transmit the value of the light sensor collected by Arduino to the PC end wirelessly. Technical

Wireless remote control uses high-frequency radio waves to control the model. For example, the 6-channel 2.4 GHz Remote Control of wfly, a set of more than 200 pieces, with automatic frequency hopping anti-interference capability, theoretically, we can allow hundreds of people to remotely control their models at the same site without interfering with each other. In addition, the remote control distance is also quite advantageous. The power of the 2.4 GHz remote control system is only less than 1
