Grades 3-5

TechASketch-mountainscape

Project Description

A classic drawing toy meets the 21st century! In this project, students assemble a handheld digital drawing project — complete with programmable LCD display, buttons, and knobs — to create their own unique artist palette. Students explore the science of displays, coordinate systems, plotting basic shapes, and creating brushes, while applying these learnings through a customizable, one-of-a-kind drawing experience.

Key Concepts

X-Y coordinates, display, pixels, algorithm, coding, debugging, loop, program, pseudocode, syntax, printed circuit board (PCB), knobs, buttons, microcontroller, USB, traces, bolts, spaces, lock washers, cap nuts, screen, primary colors, pixel, RGB colors, arguments, potentiometers, variables, analog pins, serial print, buttons, toggle, pullup input, conditional statements, accelerometer, X-Y-Z dimensions, tilt, serial print, logic statements, text, text box, transparency, variables

Essential Question

How can we use electronics and coding to create a color digital drawing device?
