Today, I will set up the Arduino and AtTiny into the Arcadia.
Since AtTiny is sensitive to heat, it is not soldered directly, use a dedicated socket.
Also, the wiring of this project are not many, I did not use a circuit board, I soldered wires directly into the socket.
I installed the Arduino to the space under the bridge first, then set up AtTiny on top of the Arduino.
In order to avoid a short circuit, AtTiny was surrounded by plastic board.
And finally, by connecting the Arduino to the PC using a dedicated board, then download the program.
Red part next to the Arduino is the board that connects to a PC.
Next is to complete the base, make sure that it works by connecting with Arcadia.
