This temperature activated project kit is also available as a light activated project kit. The output of this board can be used to control other electronic circuits, turning them on automatically when it goes hot or cold.

The board has space for an LED with current limit resistor (both available separately) which will light when the output turns on.

The Darlington pair transistor configuration allows an output current of up to half an amp to be controlled. Operating voltage 3V to 10V (lower voltages allow for better adjustment of the switching point).

This kit uses a single AA battery holder into which the user places a battery. LEDs then illuminate to show the remaining capacity of the battery. The circuit uses a quad operational amplifier to provide a reference voltage and comparators to determine which LEDs should go on. This makes it a great kit for studying operational amplifiers.

Testing of the kit can be performed using an adjustable power supply.

This is a versatile relay board kit that can easily be configured via jumpers and trimmer potentiometers to do a range of tasks.

Most sensor and switches can be connected to the input of the board and the trigger level set for the input device. This can be inverted if required, then there is the option to feed this straight to the relay or a timer of up to 25 minutes can be used. Irrespective of the state of the invert jumper whenever the sense LED goes from off to on the timer restarts.#

The board can run off any voltage from 4.5 to 6 volts.

The output cans switch DC or mains.

This datasheet details what the board does and how to use it along with some worked examples. A more detailed set of information including the build instructions & how to configure the kit can also be downloaded.

The Kitronik Deluxe Rear Bike Light Kit is easy to build kit and is an excellent way to learn about the very popular 555 timer IC. The kit uses four ultra bright LEDs that can be operated in two modes; constant and flashing.

A key design aim of the kit was that it should conform to all relevant British Standard measures. Both the flash rate and brightness conform to British Standards for vehicle road lighting (2005), making it ideal for use as a rear bike light. Alternatively, it can be used as a night safety product or flashing eyes.

During testing we connected the kit to 3 x AAA batteries and ran it continuously. At 80 hours of continuous use the LEDs were still lit at full brightness. After 107 hours, although still lit, the brightness had dropped below the level at which you would want to use them. So, we estimate that with brand new batteries you could comfortably run the light for 2 hours of daily commuting for at least an entire month with the LEDs still at full brightness.

Features:

• An easy to build rear bike light project that conforms to British Standards for vehicle road lighting (2005) for both brightness and flash rate.
• Learn about the very popular 555 timer IC.
• The kit features 4 x bright LEDs.
• It has two operating modes; continuous and flashing.
• Its compact design makes it the ideal choice for designing custom enclosures.
