I moved my domain to UpCloud (on the other side of the world) from Vultr (Sydney) and could not be happier with the performance.The routing for connection is in mess because there have to many connection between the wires. This is what I ended up with (click for big). After the schematic view shows there is no wrong on the each part of the circuit, then I will proceed on my wiring. The schematic view on the above is connection between RFID, Raspberry Pi, LCD Screen, buzzer and LED. The figure above show my first attempt to make the project more readable and its how Fritzing diagram shows on breadboard view. Then, using breadboard view, the circuit also can be export to schematic and PCB layout. First, just choose the core part for input and output. I think that trying to integrate equipment into Fritzing would be easy and fast result to make sure the connection is right or not. I choose fritzing because I can create a test specification via GPIO port using Raspberry Pi.

If there had no problem with all the connection, I will proceed to combine it with female wire and jumper. As you can see from my previous blog, the circuit have been construct based on this connection. Here, i want to testing between 16×2 LCD screen with Raspberry Pi.
