Original version: The graphics adopt the graphics of mondraker boss.
Reasons for Modification: After seeing Mondraker’s project, I couldn’t wait to build the board and buy components. When I bought the components, I found that the ceramic filament was really expensive (not to refute Mondraker’s project). 5 cents each, and the chip SGL8022W used by the boss is not available in Lichuang Mall (the majority of white* parties are directly unhappy), Taobao is still relatively expensive, and the tantalum capacitor costs about 10 yuan, although it is added It can still light up without adding tantalum capacitor. . . But the most important thing is that after I soldered it, I tried it with great expectations. Suddenly the tantalum capacitor started to smoke, which scared me to death! ! ! , (I rarely use tantalum capacitors, I am a novice) after a long experience. . . . It's finally fine. I put it in my pocket. Unexpectedly, the light broke. The frequency of the break was very fast. It costs 5 cents and 50 cents. Moreover, as a pendant, it is easier to break the light. After my collapse, I suddenly sprouted I thought of changing it. So it was born at zero cost! ! !
Advantages: Compared with the big one, this one uses ordinary LED lights, and the light will not break even if you sit on your butt. And the most important thing is zero cost (old users know how to make money*, novices are better, just register for 300,000* in Lichuang Mall* and place an order according to the product number below)
resistors and capacitors and type-c is the lowest price: () Here is the product number, just search it in Lichuang Mall.
The first model (C165948) is 1.5 yuan each. If you want to make one, choose this one!
The second model (C2927038) costs 3.3 yuan for 10 pieces. If you want to make more, choose this one! !
see below. . . . Almost all are 2.5 yuan for 50 pieces, and some are 100 pieces.
If you don’t use it for free, the total is only about 10 yuan. In addition, if you buy an extra chip, you can make one more. If you make 10 pieces, it is equivalent to 20 yuan to make 10 pieces, which is two. One yuan apiece, very nice!
............ .............
Colors can be freely combined, but please pay attention to the specifications. Different specifications will not light up. You will know this after trying it a few times! Recommended by veterans
with more patches.
Teppanyaki: fast and convenient, but easy to brown, affecting the appearance.
Manual welding: slow and troublesome, but the welding effect is beautiful.
It is recommended for novices to use manual welding to practice their welding skills and gain a sense of accomplishment.
Of course, if you want to be lazy, you can also buy it directly from Xianyu.

Introduction: A Bluetooth transport car based on ESP32. Reproduction of Station B's "Blank Innovation Studio"
A Bluetooth transport car based on ESP32. Reproduction of Station B's "Blank Innovation Studio"
premise description: He has made upgrades and transformations in his project. The specific transformations are as follows: he wants to add a camera, design a large body (used to hold various things), and add ultrasound Obstacle avoidance module can realize automatic transportation by slightly modifying the program. Modify the APP that controls the car (the original APP actually has ads. As someone who doesn’t like to watch ads, how could I allow ads to exist, so I made my own one without ads, hahahaha. Don’t worry, the APP will be optimized in the future. ) However, the current version 1.0 of the transport trolley only allows the modification of APP (because it really cannot accept advertisements). The APPs with advertisements and without advertisements are placed in the URL at the bottom. You will know by comparing them. Later, I will slowly learn 3D modeling and Android (Android) and add various modules to achieve more functions.
Price: Because it uses 32, it is not very cheap, but it is not very expensive either
. 1. The main control ESP32 is 11.5 yuan. Link (https://m.tb.cn/h.fErfnpE?sm=50d5ef?tk=7GQm2LRXWav)
2. Universal wheels: 4 wheels for 23 yuan (very cheap, okay) buy No. 3, which is the largest 68mm , very scalable. Link (https://m.tb.cn/h.fwKnf2X?sm=e6c907?tk=nZCg2LRd1pA)
3. Geared motor: 5 for only 11 yuan, keep one extra as a spare, it’s really delicious, some Xixi, link (https ://mobile.yangkeduo.com/goods1.html?goods_id=306345357662&page_from=101&pxq_secret_key=VDQEX PKH4FQFZZASQORG4O3UFHOBYGEXA6HMA6QKQHMMZYPLGCPA&share_uin=3HT3LPSFHMY5BPOIY3EXAOYPUY_GEXDA&re fer_share_id=977b1b1242e741d9b9c4589196b6095c&refer_share_uid=8811505793335&refer_share_uin=3HT3LPSFHMY5BPOIY3EXAOYPUY_GEXDA&refer_share_channel=copy_link&refer_share_form=text) Xixi link is relatively long, no problem.
4. Novices on various components recommend placing orders immediately. Needless to say, veterans, there is a table below: it only costs about more than 30 yuan.
5. 3D printing only costs 5 or 6 yuan. You can choose Taobao (compare three stores) or choose Lichuang 3D Monkey Printing,
so the total cost is about 60 yuan.

简介：本项目是基于国民技术N32G430C8L7的智能控制设备设计。
* 1、项目功能介绍
本项目是基于国民技术N32G430C8L7的智能控制设备设计，功能是能够语音识别或手机控制设备，语音识别控制通过语音识别模块识别指令，进而控制相关的设备；手机控制是通过蓝牙模块与板子进行通信，从而实现手机对设备工作进行控制。
*2、方案介绍
2.1系统方案结构
本方案设计的架构如图2.1所示，主要分为LED灯模块、语音识别模块、蓝牙模块、舵机、光线检测模块、主控制器N32G430C8L7等组成，旨在使用离线语音识别或手机控制智能设备，模拟智能家居系统。

4.1电源部分
根据国民技术提供的手册可知主控制器N32G430C8L7需要 2.4V 至 3.6V 的工作电压(VDD)，VDD 为外部电源。因此本设计的电源部分通过 USB 口供 5V 电源，再使用稳压芯片 AMS1117-3.3V 将供电电压 5V 转换成 3.3V 电压。SW1 为电源的开关；C1、C2 是输入电容，作用是对输入电源进行滤波；C3、C4 是输出电容，作用是抑制自激振荡。LED 灯为电源指示灯。电源部分的电路原理图如图所示。
图4.1.1 电源电路
4.2LED模块电路
LED模块是由四个LED灯（照明灯、红灯、蓝灯、绿灯）和限流电阻组成。LED灯的阳极接上拉电阻，阴极接IO，分别接PA4、PA5、PA6、PA7。当IO口输出低电平时，LED亮；输出高电平时，LED灯熄灭。电路如图所示。
图4.2.1 LED模块电路
4.3BOOT选择电路、复位电路、下载调试接口电路

Introduction: The project mainly involves serial communication between the 8266 minimum system and the zigbee minimum system. Zigbee assumes the coordinator function and sends the collected sub-device data to the 8266 through the serial port. The 8266 reports to the HA platform through local wifi to support a large number of third-party devices - the manufacturer is commercial There are restrictions on their own gateways due to profit reasons. Generally, private brand gateways can only access their own brand of Zigbee devices. So far, the project has supported a total of 1,402 devices from 207 different vendors. Among them, most of the zigbee products from domestic manufacturers such as Lumi and Tuya are covered. This project refers to the secondary modification made by Yaoshenz2m. For the 8266 firmware programming steps, please refer to: https://bbs.iobroker.cn/t/topic/3347/4 (the Zigbee firmware tutorial is incorrect). The first step to get it is to complete the welding. The first step of the 8266 programming program is to download the following programming tool
