• 1x PCB
• 1x 1kΩ (Brown, Black, Red, Gold) resistor
• 2x 47Ω (Yellow, Violet, Black, Gold) resistor
• 1x 0.1µF ceramic capacitor
• 1x 10µF electrolytic capacitor
• 2x 1N4001 diode
• 1x 32kHz crystal
• 1x Attiny25 microcontroller
• 1x 8-pin IC socket
• 2x Stripped wire pieces
• 1x 2xAAA battery holder with on/off switch
• 1x wall-clock

NOTE: The kit comes with a low-cost wall clock. If you intend to instead use and modify another clock mechanism, we recommend that you first use the included clock as practice to make sure that you do not damage a more expensive clock mechanism.
