PSCAD继电保护仿真模型 (PSCAD simulation examples Collection)

数字量-模拟量转换器，可以实现单片机处理的数字量信号转换成模拟量电压电流信号输出(Digital analog converter)

说明：  基于51单片机的循迹避障小车。采用红外传感器实现循迹和避障 。功能比较简单(Tracking obstacle avoidance)

stm32通过计数器测频率，很好的资料，希望帮到大家。(Stm32 through the counter measurement frequency, good information, hope to help you.)

说明：  FX2N -32MT schematic

平台为arduino uno r3，采集温湿度，气压、海拔、土壤湿度信息在5110屏幕上显示，并通过nrf24l01传到另外一个arduino采集板上，然后通过串口传给pc机。传感器有ds18b20，dht11，土壤湿度传感器，bmp085，显示屏为5110，一对nrf24l01。library文件夹下为所需的各种库。(The platform for Arduino uno R3, collecting temperature and humidity, air pressure, altitude, soil moisture information displayed in the 5110 screen, and through the nRF24L01 to another Arduino acquisition board, then transferred to the PC through the serial port. The sensor has DS18B20, DHT11, soil humidity sensor, bmp085, display screen is 5110, a pair of nrf24l01.Library folder is required for various libraries.)

基于AVR单片机的电阻测试仪，带有LED数码管显示，内有CVAVR 的C编译器和烧写软件，还有程序流程图和源码电路。(Based on AVR microcontroller resistance tester with LED digital tube display, there CVAVR C-compiler and writing software, as well as program flow chart and source circuits.)

基于430的DC_DC变化，采用PID控制，调节PWM的输出占公比，从而反馈调节输出电压(Based on 430 DC_DC change, using PID control, adjust the PWM output accounted common ratio, thus regulating the output voltage feedback)

说明：  51单片机中的开发板上的LED跑马灯程序，很简单但是很实用适合新手/。(The program of LED horse-running lamp on the development board of 51 single-chip computer is very simple but practical for beginners/ novices.)
