Arduino has become one of the easiest microcontroller platform to develop and therefore it is open source. In this post I’m trying to write down my experiment in using Arduino as 7-segment digital clock display controller driver.
Almost every Andoid application has many activities, a screen that interact with user. On desktop based operating system, this screen is usually called by a “form”. It is very common that it is required to switch between one activity onto another activity in user interaction. In this post I will try to explain how switching between activities and passing variable into it can be done.
