Alternatively, we can completely disconnect the circuit board, and connect the speaker and motor to our own microcontroller, to have direct control of the output modalities. The easiest hack would be to utilize the existing “try me” push button, to trigger the bat toy’s existing circuit board. In order to trigger the bat’s movement, we would need to connect to the existing circuit board. The goal is to have the bat toy activate when there is motion detected, or face(s) detected, and this would require use of a camera or some other sensor. Now that we have partially disassembled the bat toy, we can plan how we want to hack it. The circuit board is connected to the speakers with the yellow wires, and the “try me” push button is connected to the circuit board via the white wires. There is a little circuit board with a small microprocessor, which is powered by the battery (via the red and black wires). Opening up the plastic case reveals the bat toy’s “internal organs”. More “surgery” to reveal the bat toy’s “internal organs”. There is also a small speaker that emits the sounds, and 2 wires that connect to the “try me” push button. The bat toy’s “skeleton” is a motorized joint that swings left and right, and bobs up and down.
