This is a through-hole version of the popular SparkFun Electronics Simon Says kit. The kit lets you make your own Simon Says game, where you have to copy a pattern that gets more and more difficult until you fail to copy it correctly. This version comes with an ATmega328 processor that is pre-programmed with the Simon Says code (the source code is provided below if you want to re-write it!). All components are through-hole, making this kit great for beginners. When building this kit, you'll have a chance to solder a 28-pin microprocessor, LEDs, battery clips and more.

After you have successfully assembled the kit, you will have a greater knowledge of through-hole soldering and the tools, techniques, and terminology required to populate your own PCB prototype. You will have a development platform with 5 outputs (LEDs and buzzer), 5 inputs (buttons), and serial for debugging. And, of course, you'll have your very own Simon game! Checkout the great assembly instructions. The kit even includes batteries! Assembly time varies, but for a true beginner with no soldering experience, the kit can take 20-40 minutes to assemble.

Kit Includes:

1x ATmega328 - pre-programmed with Simon firmware

1x Buzzer

2x 0.1μF Cap

1x 10K Resistor

4x LEDs (blue, yellow, red, green)

2x Slide Switch

4x Battery Clips

2x AA Batteries

1x Button pad

1x Bezel

4x Standoffs and screws

1x Assembly instructions.

Note: This ATmega328 comes pre-programmed with the Simon code as well as the STK500 serial bootloader. This serial bootloader will allow you to re-program the Simon game using the Arduino development environment if you want to change the code for your own. There is not direct support under the Arduino IDE but the 'LilyPad Arduino w/ ATmega328' should allow you to reprogram the board using Arduino. You will need a serial to USB converter such as the Breakout Board for FT232RL USB to Serial to program the reprogram the board from the Arduino environment.

The Terminal Breakout board for the BBC microbit does exactly what it says on the tin. It breaks out all of the signal and power pins on the microbit to user friendly terminal blocks. No more untangling M/M or M/F jumper cables from the hastily tidied collection stashed in the corner of your drawer. Just cut a length of wire from one of your more tidy spools, strip off a bit of shielding and screw it into place in the appropriate terminal block. And, if you need to move your project for any reason, having the wires screwed in place means that you can do it without having to deal with the jumper connections that didn't survive the move. Build your circuit only once!

It features a terminal block breakout point for each BBC micro:bit IO pin, a switch-controlled input power terminal block, two output power terminal blocks (fed through power from the switched input) and Link compatible connections for other BBC micro:bit accessory boards. Power is provided via the input terminal block. The board has no voltage regulator, or overvoltage protection, so the supply voltage. MUST NOT exceed the rated supply of 3.3V for the BBC micro:bit.

Note: If the micro:bit is powered via its USB connector, there will be no power at the 3.3V terminal block output connections – this is to provide some overcurrent protection for the micro:bit. To use the Terminal Breakout board, the BBC micro:bit needs to be firmly inserted into the edge connector in the centre of the board. The BBC micro:bit can face in either direction and all the terminal blocks will be fully functional.

Features:

It breaks out all of the signal and power pins on the microbit to user friendly terminal blocks.

Build permanent circuits that you move without worrying about jumper wires becoming detatched.

It features a switch controlled power block and two output power terminal blocks.

There is also built in overcurrent protection what using the USB connection to transfer data to the microbit.

The microbit connects to the board via an edge connector that the microbit slots directly into, either way around.

The board complies to the Link Standard that all Kitronik branded microbit accessories conform to.

Dimensions:

Length: 80mm.

Width: 50mm.

The Monk Makes Air Quality Kit for micro:bit is based around the Monk Makes Air Quality Sensor. This add-on for the microbit measures the quality of the air in a room - how stale the air is. The outputs of the Air Quality Sensor board are analogue: one for temperature and one for eCO2 (estimated carbon dioxide). These outputs can be read by a micro:bit and either displayed, for instance, as an air quality meter or logged over a period of time for all sorts of interesting experiments.

As well as the Air Quality Sensor itself, the kit also includes a set of alligator clip leads to connect it to the micro:bit and also a Speaker for micro:bit that can be connected to provide a warning of low air quality. A full-colour 24-page booklet of instructions is also included.

To measure both temperature and air quality, the Air Quality Sensor requires four connections to the micro:bit: GND and 3V (to supply it with power) and two of the other micro:bit rings for the temperature and eCO2 readings. It does not matter which colours you use for the leads, but it is a good idea to stick to black for GND, red for 3V and any other colours for the other two leads. This just makes it less likely that you will accidentally connect power the wrong way around – although if you do make that mistake, don't worry, it won't damage the board.

Micro:bit breakout board is a kind of breakout board for micro:bit. It can lead out GPIO port, serial port, IIC port, and SPI port on the micro:bit board. The biggest feature of Octopus:bit is that it can switch electric levels for some GPIO ports, which makes micro:bit available to be adapted to 5V sensors.

FEATURES

Input voltage: 3.3V（powered by the edge connector of micro:bit）

Extend all the GPIO ports(P0~P16, P19~P20).

Beneath each I/O port, there are pins for VCC and GND. These pins are differentiated by different colors, which enable you to connect your extension module easily. The spread of pins is fully compatible with the Octopus series products.

With a voltage boosting module, you can shift the working voltage of P8, P9, and P11~P16 between 3.3V and 5V through the voltage switch.

Lead out the serial port, I2C port, and SPI port, among which I2C can connect 3 channels of I2C devices and SPI can connect 2 channels of SPI devices.

Available for direct serial port communication between two breakout boards.

APPLICATION It is suitable for all conditions that require micro:bit GPIO such as programming education, smart device creation, and so on.

The Grove Ultrasonic Distance Sensor is an ultrasonic transducer that utilizes ultrasonic waves to measures distance. It can measure from 3cm to 350cm with the accuracy up to 2mm. It is a perfect ultrasonic module for distance measurement, proximity sensors, and ultrasonic detector.

This module has an ultrasonic transmitter and an ultrasonic receiver so you can consider it as an ultrasonic transceiver. Similar to sonar, when the 40KHz ultrasonic wave generated by the transmitter encounters the object, the sound wave will be reflected back, and the receiver can receive the reflected ultrasonic wave. It calculates the time from the transmission to the reception, and then multiplies it by the speed of the sound in the air(340 m/s) to calculate the distance from the sensor to the object.

Compared with traditional ultrasonic module, the HC-SR04, the Grove Ultrasonic Distance Sensor integrates a single-chip microcomputer, and the transmitting signal and the receiving signal share one pin by time division multiplexing, so only one I/O pin is occupied. Another difference is that HC-SR04 only supports 5v voltage, while Grove - Ultrasonic Distance Sensor supports 5v and 3.3v. As we know, the Raspberry pi I/O only supports 3.3v. Therefore, Grove - Ultrasonic Distance Sensor can be directly connected to the I/O of the Raspberry Pi, but HC-SR04 needs to use a voltage conversion circuit.

Features:

3.3V/5V compatible, wide voltage level: 3.2V ∼ 5.2V.

Only 3 pins needed, save I/O resources.

Wide measurement range of 3cm ∼ 350cm.

Easy to use, grove connector, plug and play.

Possible Applications:

Distance measurement.

Ultrasonic detector.

Proximity alarm.

Smart car/buggy/robot.
