Halloween game with moving sensor (12F683)
Halloween is coming up and it's time to do some pranks. Everyone likes Halloween and I'm no exception. Every year me and my wife decorate the house with lots of bugs, spider webs, creepy posters and of course lots of Halloween candy. While making the normal Halloween preparations I came up with the idea of making a circuit that would make some scary noises and also would react to movement. I expect to get some screams and laughs from friends that come to visit us this year. The circuit is basically a sound chip that records and stores sounds in memory and plays them back with a microcontroller and it's triggered by light and motion. The sound chip is from maker Winbond and has a very good sound quality. This circuit has 2 sensors. One motion sensor (Sharp GP2D12) and a light sensor (LDR). The microcontroller monitors both sensors and triggers the sound chip in certain conditions.
Every time the circuit is powered on, the microcontroller stores the distance read by the Sharp sensor and uses this as a reference for the space available for object/people detection. Anything moving in front of the sensor up to that reference activates the first stored sound.
The other 3 sounds are time-triggered only when the light is out. The LDR senses the light intensity and only when placed in darkness will it activate the remaining sounds. Sometimes the sounds are individually played and sometimes combined. There are 4 sound slots available with a maximum length of 6 seconds each.
The PCB has some connectors with jumpers, making it possible to change from record to playback mode and vice versa.
Connector #1, named REC/PLAY, is a 3-pin connector, and jumper connection must be placed to the left side for record mode or to the right side for playback mode.
Also, connector #2, named Jumpers, must have 2 jumpers installed for playback mode. This is responsible for the memory address of the sounds.
When in record mode, some wire jumper connections must be made to change the address of the recordings manually by connecting pin 2 and 3 to VDD or VSS according to the table below:
For VDD and VSS connections, it is possible to use a connector named + -.
Recording: With power off, connect a microphone, move jumper to record mode and connect message pin 2 and pin 3 to VSS.
Turn on the power and prepare the sound you wish to record for #1 sound. Press and keep the S1 push button while recording. Release the button to stop recording. Connect pin 2 to VDD and keep pin 3 to VSS - this will address sound #2. Press and keep the S1 push button while recording. Release the button to stop recording. Connect pin 2 to VSS and pin 3 to VDD - this will address sound #3. Press and keep the S1 push button while recording. Release the button to stop recording. Connect pin 2 to VDD and keep pin 3 to VDD - this will address sound #4. Press and keep the S1 push button while recording. Release the button to stop recording. Turn the power off, disconnect the microphone, restore address jumpers and move jumper to playback mode.

This circuit design serves as an interactive Halloween prop, combining sound playback with motion and light sensing capabilities. The Sharp GP2D12 sensor is utilized for motion detection, providing a distance measurement that informs the microcontroller when to trigger sound playback. The light-dependent resistor (LDR) is integrated to enhance the experience by activating additional sounds in low-light conditions, creating an eerie atmosphere.
The microcontroller, a Microchip 12F683, is programmed to handle the logic for monitoring the sensor inputs and controlling the sound chip, the ISD 2532 from Winbond. The sound chip is capable of recording and storing up to four sounds, each with a duration of up to 6 seconds. The recording process is facilitated through the use of a microphone and a set of jumper connections that allow the user to specify which sound slot is being recorded.
The printed circuit board (PCB) is designed to accommodate all components and provide necessary connections, including jumper configurations for switching between record and playback modes. The inclusion of various resistors and capacitors ensures stable operation and signal integrity throughout the circuit.
The circuit is powered by a 4.8V battery pack, providing sufficient energy for the components while maintaining portability. A push button (S1) is incorporated for manual control during the recording phase, allowing users to easily capture sounds for playback.
Overall, this design encapsulates a creative approach to enhancing Halloween festivities through interactive electronics, ensuring a memorable experience for visitors.Halloween is coming up and it's time to do some pranks.
