Arduino-based Anatomy of the Talking Body Design for Children's Education

With the talking body anatomy tool for arduino-based children's education, children can interact directly so that the learning atmosphere is more fun. The design of this tool uses an IC555-based touch switch arranged in a matrix. An Arduino microcontroller is used to control all processes. The sound output uses an SD Card that can record sound for 120 seconds. Electricity leakage on the human body, which has a small current, can be used to trigger IC555 properly. Using an SD Card to record many messages is relatively easy because the addressing is used in parallel. Adding a digital circuit to expand the port can work well, because both have TTL voltage levels. SD Card sound recording equipment has good performance as a sound chip. Operation is relatively easy due to the parallel data communication addressing system and requires few additional external components.
