Batteries not included

LED Lighthouse Solder Practice Kit

This simple flashing LED circuit is great for learning how to solder or to polish up on your soldering skills. It uses a 555 timer in the astable configuration to flash the LEDs continuously. The rate of flashing can be changed by adjusting the variable trimmer potentiometer R2 (f ≈ 0.3Hz-30Hz). It can be powered by a 9V PP3 battery (not supplied).

The kit is supplied with Yellow LEDs by default but you can choose Red, Blue, Green or White LEDs from the drop-down list above.

Non-Contact Metal Detector Kit

Basic metal detector sensor module with buzzer and LED alarm. Will detect metal at a range of up to 60mm, including through soil, cothing, etc. Requires an input voltage of 3-5V DC, which can be supplied to the module via the 2 pin screw terminal (e.g. battery pack, USB, power supply). The sensitivity can be adjusted by the VR1 potentiometer.
