To measure the voltage, you need an ADC. Which is called Analog to Digital converter. In arduino, for instance uno has 10 bit ADC, that means you can measure whatever you want as a 10 bit resolution that also means your scale is between 0 to pow(2,10). If you have […]

Here, the basic idea of the elevator system that you can find. Using arduino to create an elevator is so easy. Only you need an algorithm which controls stepper, servo and buttons. Before understand the code, I need to say I can not explain the structure of the elevator. You […]
