Measure the power consumption of an output device.
Practically we were searching up all about different devices that we can use for this practice. Power consumption measured in watt (usually in milliwatt, mW) is the correct term for low power applications but all too often the current consumption measured in ampere (usually milliamperes, mA) is used instead. As the power is just the operating voltage multiplied by the current, this is trivial for fixed voltage operations but becomes more tricky to estimate when using batteries that discharge and the voltage changes over time and loading conditions. It is usually the energy consumption measured in Joules (usually in micro joules, µJ) that determines how much energy is actually drained from the battery to complete a specific task. The energy consumption will be the integral of the power consumption over the time needed to perform the operation. Again, with static signals this would be a simple multiplication of power consumption and the time but with varying signals this will demand more complex analysis. link with more information
More details before the practice. I was checking information about displays because I would like to get some information about the input devices in this case flex sensors. The idea is to propose some kind of reading where I can represent degrees of flexibility in every single finger.The LiquidCrystal library allows you to control LCD displays that are compatible with the Hitachi HD44780 driver. There are many of them out there, and you can usually tell them by the 16-pin interface. This example sketch prints "Hello World!" to the LCD and shows the time in seconds since the Arduino was reset. The LCDs have a parallel interface, meaning that the microcontroller has to manipulate several interface pins at once to control the display. The interface consists of the following pins:
We started the practice with Tinkercad, but first .

Connecting measurement tools.

Individual assignment: Add an output device to a microcontroller board you've designed, and program it to do something.
Afterward, I couldn´t continue with this design because I didn´t verify the microcontroller ATTINY 1614 I used, then I invest hours practicing with Eagle and it was a good experience, but with this new knowledge, I could apply it in the development of the final project.
