When developing for embedded systems, having knowledge about electronics gives much more freedom on what we can create. Instead of using only shields or demonstration boards, we can develop custom solutions for our needs, allowing for a greater efficiency and a lower cost.
This post explains some very basic principles about electronics, namely DC voltage sources and resistors. I’ll try to make some posts about more basic electronics every once in a while, in order to complement the other posts about embedded systems.

This post describes a prototype of a smart medication dispenser, created with an Arduino as the controlling unit. The hardware platform and the software to support all the functionalities were created from scratch. Some of the functionalities include the possibility to connect the dispenser to a smartphone using HC-06 bluetooth module, or to communicate with a remote server through the internet, using ESP8266 Wi-Fi module.

Following the previous post on how to structure data, this one describes an application specific approach, based on the concept of commands and built on top of the previous structure.

In the development of embedded systems applications, transferring serial data without any high level structuring is a bad practice. Although this is a quick way of testing, it’s not good idea to just send bytes of information and expect that everything will work fine, in a final application.
