Luminous Touch Toy

Luminous Touch Toy made with NE555 IC and a piezo-electric sensor, with auto-off functionality.

 

This project use the following electronic components:

• 1 x Integrated circuit NE555
• 1 x Piezo-electric sensor
• 4 x Multi-color LEDs
• 4 x 330 ohm resistors
• 1 x 10k ohm resistors
• 1 x 100k ohm resistor
• 1 x Transistor BC547 NPN
• 1 x Electrolitic capacitor 100uF 10v
• 1 x Switch-button
• 4 x Bateries 1.5v
• Some Empty Pen Tubes

The circuit:

• When pressing the toy surface it moves the empty pen tubes, making some presure on the piezo-electric.
• The piezo-electric generates some voltage on presure, activating the electronic circuit.
• The NE555 IC handles the 12 seconds enabled delay.

Notes:

• KiCad 6.0 schematic & PCB blueprints are also included.
