This paper firstly introduces the properties of AVR single chip, the performance of AVR MCU design the control board of the corresponding circuit, and to study its programming method, is convenient for the users to operate, it is applied to the hardware.

Introduction of a Device for Automatic Collection of Potential Data and its Application in Pipeline

The pipeline cathodic protection monitoring was used in potential test of cathodic protection in pipeline. The test period was last 1 or 2 months or longer. the measurement accuracy and reliability of testing data are affected by testing environment and the accuracy of the instrument in some ways, so in order to meet the requirement of cathodic protection potential monitoring, it is necessary to design a cathodic protection potential acquisition system to realize the automatic monitoring of cathodic protection potential, the system was an automatic acquisition pipeline potential device used in buried steel pipeline environment. The internal circuits of the device used single chip design of low power consumption and are high precision DC voltage and AC voltage effective value measurement device all based on AVR MCU, combining hardware with software, the results show that the system realizes the automatic acquisition of buried pipeline potential and completes the indicators in China.

The Design of Fire Proof Leakage Current Circuit Protective Device Based on AVR MCU

Fire proof leakage current circuit protective device is a kind of protect devices. It monitors the leakage current of power supply. When they have some trouble, it shuts down power supply. Beginning from the design, the paper introduces the process of Fire proof leakage current circuit protective device design including software and hardware based on AVR MCU.

Design and Implementation of the Control System for Two-Wheeled Self-Balancing Vehicles

A control-system design for a two-wheeled self-balancing vehicle is discussed in this paper. We have developed a low-cost hardware platform based on AVR MCU, accelerometer sensor and gyroscope sensor, for which the critical circuits, such as sensors and motor driver, are introduced. The control strategy operates by two steps: a) securing the real-time vehicle posture by integrating the data from accelerometer and gyroscope sensors; b) using a closed-loop PID controller to keep the vehicle balanced. This control system is applied to a prototype two-wheeled self-balancing vehicle, whose performance has turned out to be a satisfaction.
