使用7段显示器和555定时器的两位计数器Two Digit Counter
➀ 本文介绍了一个使用7段显示器和555定时器构建两位计数器的DIY项目。
➁ 计数器每收到一个时钟脉冲就从00增加到99,并在达到99后重置,分别控制个位和十位数字。
➂ 该项目解释了电路设计和工作原理,涉及如LM555定时器、CD4033十年计数器和7段显示器等组件。
➀ This article introduces a DIY project for building a two-digit counter using a 7-segment display and a 555 timer.
➁ The counter increments from 00 to 99 with each clock pulse and resets after reaching 99, featuring separate control for units and tens digits.
➂ The project explains the circuit design and working principle, involving components like LM555 timer, CD4033 decade counters, and 7-segment displays.
