摘　　要：利用Arduino Uno、DAC0832元件、JHD-2×16-IIC液晶模块、各种运算放大器元件、7805稳压块等实现可调稳压电源。初始化电压为10 V,通过增加或减少按键实现当前输出电压按照0.1 V的步长增加或减少,进行输出电压的调整,输出电压范围为4.5~16.5 V。该系统具有硬件电路简单、操作方便、输出电压范围宽和精度高、输出电压增加或减少步长小、驱动能力强的特点。Using Arduino Uno, DAC0832 element, JHD-2×16-IIC liquid crystal module, various operational amplifier elements, 7805 regulator block to achieve the regulated power supply. The initialization voltage is 10 V. The current output voltage can be increased or decreased according to the step size of 0.1 V by increasing or decreasing the key. The output voltage range is 4.5~16.5 V. The system has the characteristics of simple hardware circuit, convenient operation, wide range and high precision of output voltage, small step of increasing or decreasing output voltage and strong driving ability.
