小计算器价格便宜,耗电少,体积小,是很好的计算工具。经过简单的改装,配上适当的电路可以用作计数器、运算器和数字打印机,可用于工业生产中运行速度不高的场合。一 小计算器用作计数器1.工作原理计算器清零后,用手按下“+”和“1”键(即计数准备)再按一下“=”号键,此时显示为1,以后每按一次“=”号键,显示结果均系原基础上加1,因此,小计算器可以作为计数器使用。 Small calculator cheaper, less power consumption, small size, is a good computing tool. After a simple conversion, coupled with the appropriate circuit can be used as counters, calculators and digital printers, can be used in industrial production in the run-time is not high occasions. A small calculator is used as the counter 1. Working principle After the calculator is cleared, press the “+” and “1” keys (counting preparation) by hand and then press the “=” Press the “=” key once, the result is all based on the original plus 1, therefore, the calculator can be used as a counter.
