First attempt: bluetooh module

The first time we tried to connect by bluetooth two projects, we have a lot of difficulties with the module RN4871.

We put the wrong voltage, used the wrong FTDI cable, and then the chip didn't worked.

Three times we didn't get the chip to work. Three times, we burnt the chip or didn't get any signal from them 😖.

So, for this time, we have to quit and keep going forward 👋

Second attempt: serial / One-Wire

So, we connected two projects, one board from Electronic Production from Patricia Samudio's assignments and one input board from Alejandro Tejera's assignments.

Patricia's board was the “push button” from the electronic production week, and Alejandro's the Ds18b20 sensor board.

We plug them with the ISPs, and uploaded the arduino sketch of the sensor. And then, we started to read the signal in the serial monitor.
