摘要：Countingthings is a tool that can be used to perform a calculationthat has a display output in seven segments. The circuitis easier to do a calculation of goods that enter or exit.Output can be directly seen displayed by seven segments.The board may make counter Up, Down and Reset counter.Tools of this triple-digit counter goods using voltage of 5volts and is built with some parts of the input (switch upand switch down), oscillators, up / down counter, reset, de-coder output. Based on test results, obtained output inaccordance with the workings of this tool. By moving theswitch Up will mengcounter rise (000-999) and the switchdown will mengcounter down (999-000) to reset the switchby moving the reset and output in the seven segment willreturn on the initial state (000). The downside of this toolis limited only to three-digit calculation, because the toolis only used three seven segments in the output. And be-cause it uses a seven segment display output is quite small.Bibliography (1987-1999) 20101489
