摘　　要：利用Arduino Uno、DAC0832转换器、1602液晶模块、LMC6484运算放大器元件等制作可调直流稳流电源。系统上电复位时输出电流为0.00 A,通过外部设置的ADD键和DEC键,按照0.01 A的步长调整输出电流,其最大值可达到0.50 A。实测表明,按键操作与输出电流相对应,操作简单,输出电流稳定且精度高,达到了设计要求。In this paper, the Arduino uno, DAC0832 converter, 1602 liquid crystal module, lmc6484 operational amplifier elements are used to make adjustable DC current stabilizing power supply. When the system is powered on and reset, the output current is 0.00 A. The output current is adjusted according to the step of 0.01 A through the external key ADD and DEC, and the maximum output current is 0.50 A. The actual measurement shows that the key operation corresponds to the output current. The operation is simple, and the output current is stable and has high precision, which meets the design requirements.
