Hello Kitty stickers to renovate the dormitory, compared with this is simply weak! Based on the 51 single-chip platform, the smart home control system can realize the opening and closing of lighting, TV, curtains and other equipment in the dormitory, and supports wireless and wired access. As a geek, can this satisfy your smart home dream?
This miniature quadcopter uses STM32F103T8U6 (STM 32F103T8U6 data sheet) + MPU6050 (MPU6050 data sheet), open source programs and PCB diagrams, and has a host computer to share with everyone.
The accessories provide the aircraft schematic and PCB, flight source, test program, PC software, and related chip data.
Using STC89C52 single-chip microcomputer, P0 port 8 data bits control two motors in two, a total of four motors; use LM2575 output positive 5v power supply, there are two usb interfaces on the main control board, one serial port debugging interface; the accessory provides the upper computer Android program, lower-end machine MCU source program, compiled successfully file.
A set of quadrotor UAV controller system was implemented using the STM32 development board and the expansion board design drawn by AlTIum Designer board design software. At the same time, a set of PC and mobile APP ground station control software was written and added to GPS. Inertial navigation allows the aircraft to achieve smooth high-speed flight under the control of the ground station or remote control, and can achieve airborne stability. The aircraft can achieve autonomous cruising according to the path planned by the ground station, and can carry the aerial photography task with the camera equipment.
The air mouse is an input device that operates the screen cursor like a traditional mouse, but does not need to be placed on any plane, and can be used directly by shaking or moving in the air. Freedom and convenience is its characteristic. For example, it can be used as a briefing pen in the office field, so that the person doing the PPT demonstration no longer needs to sit at the conference table to play with the computer, and can remotely control the functions of mouse operation and page turning.
Are you tired of traditional fixed-wing aircraft models? Try this mini quadcopter! This aircraft is realized with STM32F103CB. It has been successfully produced some time ago, the accessories are completely available, remove the gorgeous shell and let the PCB fly!
This is a 3D package library that has been slowly accumulated. It is relatively complete, and most of the components are available. The total size is 30M. The contents are: full range of resistors, capacitors, inductors, diodes (inline and patch), TQF, Sop,sot,ssop,TSSOP,DIP,QFN,LQFP,plcc chip,TO-220,228,252,260 series,headphone interface,USB interface,full series pin header,FFC interface,memory card,sim card holder,crystal oscillator .
Using the handle to control the aircraft is a past tense. Today we will introduce a simple and convenient WIFI technology control aircraft. As long as you have an Android mobile phone, you can have a good Android AP and install it directly. I hope everyone can use the aircraft. Interested.
(PCB diagram, mechanical structure, circuit design)
This hexapod robot uses STM32F103RET6 as the core controller, SolidWorks as the mechanical structure modeling platform, and AlTIum Designer as the electronic circuit design software. It has completed the following functions: 1. Two walking modes; 2. Bluetooth wireless remote control 3, ultrasonic obstacle avoidance; 4, voice signal activation; 5, battery power detection.
Summer is here and the fans are starting to work. But if you have a smart-controlled fan, you can alleviate the summer irritability. This design has three smart points: through the temperature detection to the instant test, and then automatically adjust the fan blade speed; the infrared sensor feels the presence of people, automatically shut down when no one; assembly Bluetooth module, you can use the phone to control. With these three points, this is no longer an ordinary fan. The author also provided a video to first feel how the fan works.
This portable wearable device is based on the concept of high reliability and low power consumption, filtering and shaping the collected data, and finally achieving accurate step counting; using various wake-up mechanisms to reduce power consumption. This design is a multi-function pedometer, using KL25Z as the main controller, the acceleration sensor MMA8451Q is selected, the system design is based on uC/OS-II, and the interface design is based on uC/GUI.
It is said that bringing children is a very headache. Although I have not had the chance to experience it myself, I can feel the same (sadly..... I can only feel the same for a long time), this smart baby stroller seems to be participating. The game that won the first prize in the competition has been put into production after being changed. The future is not limited. The smart stroller is too powerful and difficult to produce, so it is a good choice for learning.
This parking lot management system is recommended to prevent the parking phenomenon. This system is based on the STC89C52RC single-chip parking management system. It uses the RC522 RF module, DC gear motor drive, 12864 LCD module, and involves the use of RF technology. The method of detecting the rotation angle of the motor by using a potentiometer is realized.
This is a good set of materials that are very suitable as a graduation design material. Of course, it can also be used as a complete set of materials for electronic enthusiasts. Based on 51 single-chip microcomputer, the intelligent power control function of the target device is realized, which is stable, safe and efficient. The annex contains all the PCB source files, electrical schematic source files, program source code, design & production and other complete materials. Detailed information, refusal to know a little, with detailed ideas, design, production tutorials, to help you, you still need to hesitate?
How to help you challenge the rhythm master, you will know after reading this production. Using STM32, through the detection, Schmitt trigger circuit and other circuits, the tiny capacitance change amount is converted into an electrical signal, and then transmitted to the host computer through Bluetooth. Have video, all production materials! From now on, fruit is more than just fruit. . . . . .
