FAQs
Does this kit come with all necessary components?
The kit includes the PCB and electronic components, but you will need to provide your own 2 x AAA batteries and tools for soldering.
Is soldering required?
Yes, the WSAK129 is a DIY kit that requires soldering to assemble the circuit and motor connections.
Can I change how the bug walks?
Yes, the kit features a selector for two different walk styles, allowing you to customize its movement.
What happens if the room is completely dark?
The Microbug is designed to stop moving automatically in total darkness.
What is the recommended age for this kit?
While it depends on the individual's experience, this kit is suitable for hobbyists with basic soldering experience, typically ages 12 and up with adult supervision.
Troubleshooting
The robot does not move when exposed to light.
Check all solder joints for cold connections and ensure the batteries are inserted with the correct polarity.
The robot moves in circles instead of straight.
Verify that both motors are receiving power and adjust the sensitivity settings to balance the light detection input.
LED eyes do not light up.
Ensure the LEDs are oriented correctly; LEDs are polarized and will not function if installed backward.
Pros and Cons
Pros
- Excellent project for learning basic soldering techniques
- Interactive behavior provides instant gratification upon completion
- Customizable movement and sensitivity settings
- Compact and lightweight design
Cons
- Requires manual assembly through soldering
- Batteries not included in the kit
- Small components may be challenging for absolute beginners without supervision
Setup, Compatibility & Care
To set up the Microbug, you will need basic soldering tools including a soldering iron, solder, and wire cutters. Follow the provided schematic to mount components onto the PCB, ensuring the polarities for the LEDs and transistors are correct. Once soldered, insert two 1.5V AAA batteries into the integrated battery holder.
To ensure longevity:
- Periodically clear debris from the motor shafts to prevent mechanical strain.
- Store the unit in a dry environment to prevent oxidation on the exposed circuit board.
- Use fresh alkaline batteries to ensure consistent motor voltage and reliable light detection.
