Connect Arduino to Raspberry Pi

There are few ways to connect Serial Gateway (Arduino) to Raspberry pi, the easiest one is to connect Serial Gateway (Arduino) via USB port to raspberry pi. This is be easiest way and saves hassle of all wiring on other hand we can use serial pins on raspberry pi to connect to Arduino which is little bit difficult but we are here to build everything our self so let’s build pcb board with all components connected and get this job done neatly right on the rpi.

Hardware Parts List

1 x Arduino Mini Pro 16Hz 5v
3 x 10uf Capacitor
1 x NRF24l01 pa lna Module
1 x Logic Level Converter – Bi-Directional


Lets connect Raspberry pi to Arduino through bi-directional logic level converter, remember we are using Aruduino nano pro 5v version and make sure you connect pins correctly otherwise you can damage your rpi
