Mr Bit Downloads for Kitronik Discovery Kit Experiments
The Kitronik Discovery Kit for the BBC micro:bit is ideal for beginners who have
no experience of connecting or controlling external components. The simple breadboard,
together with a range of LEDs, a piezo sounder, resistors and jumper wires, makes
it easy to build simple circuits with no previous skill. With Mr Bit files you quickly
discover how a simple program makes the micro:bit become a powerful controller. The
An LED (Light-
In this experiment when button A is pressed, pulses are are produced at a fixed frequency which make the piezo sounder emit a simple steady tone. When button B is pressed, a series of stored frequencies is used to sound as a tune. The Mr Bit control system contains a music editor which can be seen in Design mode.
The program in the Mr Bit control module contains a sequence of three instructions which continue in a ‘loop’ until you switch off the battery. Each instruction lights up a different colour LED for a short time.
Three coloured LEDs give an indication of the temperature sensor in the micro:bit: green is low and red is high. The program shows how the Mr Bit control module for each LED detects a different temperature.
To adjust the temperature, click on its box.
The Traffic control program lights the red, yellow and green LEDs in the UK traffic light sequence when button A gets pressed. When the Red LED is on, the stick image becomes animated and the buzzer bleeps.
