The semaphore is one method of communication that can be used for long distances [1]. This method is a way to convey information non-verbally with the help of additional signaling tools. This step is taken because there is a relatively long distance between the information giver and receiver. The message is conveyed using this method with the help of two semaphore flags, colored red and yellow, tied to a pole approximately 60cm long and held by the right and left hands, as shown in Figure In Ind
