Una de las cuestiones que más se nos han atrancado durante este #ProyectoHEIMDALL radica en la División de Obstáculos. 

Para equipar a nuestro casco con un sistema que permita a su portador desplazarse por una estancia con visibilidad nula, estamos prototipando lo que nosotros llamamos el "BATMODE". 

Este modo de funcionamiento está constituido por tres sensores láser VL53L1X de distancia que se conectan a Raspberry Pi a través de GPIOs i2c.

The I2C interface (it’s actually I²C or I-squared-c but nobody wants to type that, hence the nickname) is the end point of an inter-integrated circuit serial bus that doesn’t need high-speed communication. The transmission is synchronous and packet-switched and can host multiple masters and multiple slave devices on the same bus. You’ll find it used anywhere. Simplicity is more important than speed and it’s commonly used for attaching sensors or monitoring equipment.

We have already examined the I2C bus in a fair amount of detail. We have seen how the I2C bus works, and how we can create our own I2C sensors and devices using an Arduino. Today we will take another look at I2C, and this time we’ll be using both an Arduino and Raspberry Pi.
