ElapsedTime - Blocks
Introduction to ElapsedTime
When using our gamepad, we can actively communicate with our robot while our program runs. Our robot waits for our input and acts accordingly until a different command is issued. However, this may not always be the case, such as during the autonomous period of a FTC competition.
Our robot is smart enough to navigate some on its own, however we need to help it along to know what to look for. Eventually, you could work up to your robot being able to navigate using a camera and machine learning or its IMU to sense direction, but for now let's start with one of the built in features of the SDK: ElapsedTime
What do you think of when you think of a timer? A stopwatch? Your phone? Maybe the timer on a microwave or oven? Timers commonly consist of two main categories: count up and count down. You can think about the differences of these two by a comparison like keeping track of how fast a runner did a 100m dash vs. needing to know how much longer our food should cook.
ElapsedTime is a count up timer. Registering the amount of time elapsed from the start of a set event, like the starting of a stopwatch. In this situation, it is the amount of time passed from when the timer is created or reset within the code.
