Crumble Resources: Automation Ideas

(0)
This open-ended project combines Design & Technology and Computing. How can we make our lives easier through automation? Using the Crumble Controller, children can investigate ideas, come up with solutions and make them! LO: To create automation using inputs and outputs Success criteria: All children will design an automatic device Mastery: children will consider how their device will work, and get a basic device Greater Depth: children will have a completely working device, with the most efficient code. Difficulty: Beginner+ For this project you will need: One Crumble with USB lead; A computer with the Crumble software installed; A battery box with batteries (not rechargeable); A selection of Crumbs (components); Croc-leads. You will also need a selection of craft materials and resources. To see some examples, visit: https://redfernelectronics.co.uk/projects/creating-automation-project/
Crumble Resources: Reaction Timer

Crumble Resources: Reaction Timer

(0)
Contains the information needed to make a reaction timer, using the Crumble Controller. LO: To use selection and variables within a program Success criteria: All children will have created the sequential lights, controlled by a switch; Mastery: children will have a reaction timer that ‘shows’ the player’s score; Greater Depth: children have refined their programs so that they are more efficient, and included a ‘next step’ so that the reaction timer counts down until the next go. *Difficulty: Intermediate * For this project you will need: One Crumble with USB lead; A computer with the Crumble software installed; A battery box with batteries (not rechargeable!); A Sparkle Baton; A push switch; Seven croc-leads. Links to the curriculum: Computing: Design, write and debug programs that accomplish specific goals, including controlling or simulating physical systems; Solve problems by decomposing them into smaller parts; Use sequence, selection and repetition in programs; work with variables and various forms of input and output. Design and technology (if designing a ‘product’): Apply their understanding of computing to program, monitor and control their products.

Crumble Resources: Countdown Clock

(0)
Contains the resources needed to make a countdown clock, using the Crumble Controller and a servo. It’s a great lesson for understanding how a servo works, and using an input to control an output. It also brings cross-curricular links with maths and possibly D&T. LO: To use sequence, selection and repetition Success criteria: All children will create a visual 30 second timer Mastery: children will control their timer using a push-to-make switch Greater depth: children will add in buzzer beeps, which increase in frequency near the end of the timer Difficulty: Intermediate For this project you will need: One Crumble with USB lead; A computer with the Crumble software installed; One battery pack with batteries (not rechargeable); One servo (and Crumbliser); One buzzer; One push-to-make switch; Nine croc-leads. To make the clock you will need: Card and pens or Printed template; Scissors; Tape; Glue; Two split-pins/paper fasteners. Links to the curriculum (KS2): Computing: Design, write and debug programs that accomplish specific goals, including controlling or simulating physical systems; Solve problems by decomposing them into smaller parts; Use sequence and repetition in programs; work with various forms of input and output. Design and technology: Apply their understanding of computing to program, monitor and control their products. Maths: Know the number of seconds in a minute (year 3); Recognise angles as a property of a shape or a description of a turn (year 3); Draw given angles and measure them in degrees (if drawing a clock face)(year 5); To see step-by-step instructions, visit here

Crumble Resources: Lighthouse Project

(0)
Contains the resources needed to produce a Crumble Controlled lighthouse. It’s a great cross-curricular lesson, with the potential for a lot of research into lighthouse, and how the pattern of lights is unique. LO: To use an input to control an output Success criteria: All children will create a light sequence for a lighthouse; Mastery: children will use a toggle switch to control when the light shines; Greater depth: children will use an LDR to sense when the lighthouse should become active. For this project you will need: One Crumble with USB lead; A computer with the Crumble software installed; One battery pack with batteries (not rechargeable); One Sparkle; One toggle switch or one light-dependent resistor; Seven croc-leads. For the lighthouse build you will need: Card; A clear plastic cup; Tin foil; Scissors/craft knife; Glue/tape; Coloured pens/pencils or paint. Links to the curriculum (KS2): Computing: Design, write and debug programs that accomplish specific goals, including controlling or simulating physical systems; Solve problems by decomposing them into smaller parts; Use sequence, selection and repetition in programs; work with various forms of input and output. Design and technology (if making own models): Apply their understanding of computing to program, monitor and control their products. Potential geography link: Use fieldwork to present the human features in the local area using a range of methods, including digital technologies.

Crumble Resources: Police Lights Project

(0)
The resources needed to make a Police car using the Crumble Controller. This makes a nice starting project, as it is simple to achieve. By adding motors and wheels, you could really go to town making your own vehicle - perfect for a KS2 D&T project. Difficulty Rating: Beginner For this project you will need: One Crumble with USB lead; A computer with the Crumble software installed; One battery pack with batteries (not rechargeable); Two sparkles; Eight croc-leads. If making the police car model, you will also need: Printed template; Scissors; Coloured pens/pencils; Glue; Masking tape. Links to the curriculum (KS2): Computing: Design, write and debug programs that accomplish specific goals, including controlling or simulating physical systems; Solve problems by decomposing them into smaller parts; Use sequence and repetition in programs; work with various forms of input and output. Design and Technology (if making own models): Apply their understanding of computing to program, monitor and control their products. To see step-by-step instructions, visit here

Getting Started with the Crumble

(0)
In this video, Joseph, creator of the Crumble Controller, explains the contents of the Starter Kit and how to use Sparkles (addressable RGB LEDs). The Crumble is an easy to use programmable microcontroller, aimed at getting children (and adults!) into programming and Design and Technology. With its four inputs and outputs, along with a built in motor driver for two motors, this small board packs a punch. It’s easy to get started, connecting switches, motors, buzzers, LEDs etc. and is programmable using our free block-based software, inspired by Scratch.
