h1. Construction of a BATmonitor

{{>toc}}

Present mini-project will develop a Battery monitor using an Arduino Uno R3 and the uCANca tools.

To build a testable circuit, we will implement a solution like this one:

After we have played with the potentiomenter, the idea is to switch the input to monitor the battery level of a robot or toy controlled by the Arduino.

h2. Project creation

We will create a project called BatMonitor in uCANca.

And add ourselves as team member (as contributor).

Add the main function of the system: Monitor the battery voltage value.

Add the secondary function of the system: Discretize battery voltage values into different battery ranges.

Add a diagnostics function on battery: Warn (and register) battery low levels.

And another diagnostic function for battery high:  Warn (and register) battery high levels.

As summary:

To make the system more testable, we will introduce a function that uses the LED to inform of the current situation of the system:
