Are you excited about Halloween? Are your Halloween decorations ready yet? If not, they sure will be after this course.
In this project, you'll build a spooky LED lamp. And you can choose between three different circuits:
- A simple circuit using LEDs and resistors that is always on (Difficulty: Easy)
- LEDs with flame-like effects using Arduino (Difficulty: Medium)
- LEDs with flame-like effects using ATtiny85 (Difficulty: Medium+)
You can use a real pumpkin, a 3D printed one, or a spooky mummy using a simple jar. In general, you'll have many options to mix housing with electronics to match your skill level!
Parts List for Always-On Lamp
- 9V Battery
- 3 x LED
- 3 x Resistor (1 kΩ)
- Breadboard or protoboard for soldering
Parts List for Flickering Flame Lamp with Arduino
- Arduino
- 3 x 220 Ω Resistors
- 3 x LED
Parts List for Flickering Flame Lamp with ATtiny85
- Attiny85
- Battery 9V
- 7805 Voltage Regulator
- 1 µF Capacitor
- 0.1 µF Capacitor
- 3 x 220 Ω Resistors
- 3 x LED
- Breadboard or protoboard for soldering
For this one, you also need an Arduino Uno for programming the ATtiny85 unless you have a dedicated programmer.
