Arduino is a free hardware platform, based on a board with a microcontroller and a development environment (software), designed to facilitate the use of electronics in multidisciplinary projects. . Its clock sources are used for watch-dog and power-up timing, but it can also be used as a clock source for the operation of the entire microcontroller. 89c51 microcontroller digital clock - Project circuit diagram. The optimal clock source for an application depends on many factors including cost, accuracy, and environmental parameters. The timers and counters provide all timing and counting functions inside the microcontroller. In electronics and especially synchronous digital circuits, a clock signal (historically also known as logic beat [1]) is an electronic logic signal ( voltage or current) which oscillates between a high and a low state at a constant frequency and is used like a metronome to synchronize actions of digital circuits. Microcontrollers usually operate at lower speeds, around the 1MHz to 200 MHz range, and need to be designed to consume less power because they are embedded inside other devices that can have greater power consumptions in other areas. .
