Druiven's Arduino electronics starter kit

This is the basic electronics kit I order from Abra. It allows grade 10 and 11 students to complete many different labs and challenges with the Arduino.

The Move Craig Kielburger Secondary School part 1

Work on the new school is proceeding apace. Dan and I had our first look at what will be our new digs on Feb 1. The 2 rooms pictured here replace the V135 Robotics lab facility at Drury. 1107 will be a Computer Lab and 1108 will be a Technology Lab with workbenches and CNC machines.

Calling V135 "Robotics" was a spontaneous gesture so I'm thinking about the name for 1108. The idea of something like a "Hacker Space" appeals to me but may sound too geeky.

Will the Tech. Design lab be the new Library?

We have been building the resources available to our students in our Tech. Design (Robotics) lab this year. Earlier this fall an old CNC lathe (last used 15 years ago) went out to be refurbished. We anticipate its return shortly. In the mean time an old vinyl cutter caught the eye of our students. They make original vector graphics produced by tracing original or bitmap artwork in Corel Draw. The old cutter has been replaced by a new model that is faster and more accurate on small details. Along with a heat press the students will be able to produce custom t-shirts. The students also use a CNC router and a Desktop CNC mill to complete design projects.


As I think about the robotics lab in our new school, Craig Kielburger Secondary, I've been thinking about how neat it would be to add a 3D printer to the mix. That's why this weeks Spark episode really grabbed my attention. Have a listen. Maybe 'Hacker Space' would make a better name for shop?
.... I wonder!

ACSE Arduino Presentation notes

Slide Notes
1 Cover
2 Why Arduino? Demise of OOPic made me look around and start comparing.
Aside OOPic Raptor currently under development.
3 Chart side by side comparison.
- all similar
- all basic von neuman, single step ALU
- some pipelining and more modern characteristics but basically all one instruction per clock tick
- Arduino development board (currently UNO) price very competitive
- sparked international interest due to open source nature
4 Why Microcontrollers are a great fit with curriculum and broad-based philosophy
- can teach basic electronics
- can teach interfacing
- can teach robotics
- opportunity for students to explore and design projects
5 Why Arduino? - cheap, robust, open source,
- started Microcontroller Investigation thread on blog in June 2010
- spent time at home playing and learning
- OOpic and electronics experience helped me
- have introduced OOPic into OISE AQ courses with excellent results
- all candidates able to expand their knowledge and skills using this platform
6 7 8 On line community: Make, Instructables, Arduino.cc
- grade 12 students able to take ideas and projects and apply in the classroom
- examples of Arduino daughter boards manufactered in class
9 Open source, exciting range of 3rd party developers
- 2 examples: 1 driving LCD another driving the Pong game
10 Getting started - plug it in, Load the driver - in drivers folder
- may be difficult depending on admin. restrictions on computer
- Mac, PC or Linux
11 Start the software
- work through learning and playground ideas
- try blink, fading and LED bar graph (if you have one)
- many youTube videos
12 C, J all the same
13 Main Arduino.cc page organization



14 Learning example - uses Fritzing
15 Fritzing.org for great graphics software to go along with Arduino and breadboards
- free software - produces jpg. files like slide 14
16 - a line follower robot built during the 2 week AQ this summer
- one built by Igor Kourinnyi on display
17 - novices able to complete stepper motor driver
- improved confidence and understanding
18 - sources for Hardware:
- Creatron Inc, 255 College St. Toronto, creatroninc.com
- Robotshop.ca
- Abra
- CanaKit
- Deal Extreme (rev 1 with a different USB to serial chip)

What does "Tech Savy" mean to you?

Lots of stuff worth considering in this CBC Spark episode. Sure Junior can type 120 wpm on a smart phone but can he do an effective search for material for his essay?

Robotics - Lesson Plan

Topic: Computer Technology TEJ4M – How to Create a Robot	Notes
Context: Approximately 20 – 25 Instructional Days
Learning Outcomes: A3.1 use technical terminology to accurately describe the specifications for electronic components and computer interfaces; A3.2 describe the function and operation of various input devices, output devices, and electronic circuits used in interface and control systems; A3.5 research and select components based on circuit requirements; B1.3 construct and test connection media for interfacing a computer with an external device; B3.1 use a design process and appropriate software design circuits; B3.3 safely construct electronic circuits for interfacing or robotic applications using appropriate materials, tools, and techniques, including soldering; B3.4 test and troubleshoot electronic circuits, using appropriate methods and test equipment and modify the circuits to meet design requirements if necessary; B5.2 apply programming concepts including subroutines, parameter passing, decision and repetition structures, arrays, and character representation; B5.3 use a design process to create a program that interacts with a real-world device; B5.4 write a low-level program that runs on a real or simulated controller device.

One was for specifications and the other was for programming. Line Sensor Specifications – http://www.robotshop.com/world/sfe-digital-ir-line-sensor-qre1113-2.html Programming - http://bildr.org/2011/06/qre1113-arduino/
Tools Required: Phillips screw driver, soldering iron, pliers, wire cutters, wire strippers, multi meter, super glue, safety glasses, drill press, band saw machine, needle nose pliers, scissor, electrical tape.

Step-by-Step Instructions: Collect all needed parts Modifying HS-311 servo motors for continuous rotation Cut the baseboard to accommodate Arduino UNO board and breadboard for electronic connections Attach brackets to servo motors so they can be attached on the baseboard Drill holes and attach modified servo motors to the underside of the baseboard Attach wheels to the servo motors Attach the “third leg” to the underside of the baseboard so the robot can move smoothly Attach Arduino UNO board with Velcro and breadboard to top of the baseboard (breadboard is preferred at the front of the breadboard) Install battery holder (4 AAs) on the underside of the baseboard with Velcro. Connect (used) AC/DC Power Supply Adapter Plug to the 9v battery pigtail. Connect wires of the servo motors to the Arduino board through the breadboard (Red wire - 5V, Black wire - GND and Yellow wires - pin 9 or pin 10 PWM of the Arduino) Write a program on the Arduino board so it can control rotation of the wheels Design the front board (front loaders) to be attached to the baseboard to accommodate QRE1113 line-sensors Attach two QRE113 line-sensors on the inside bottom of the front loader. One on each side of the front-loader Solder the wires to the line-sensors so they can be connected to the breadboard. The sensors should be about 3 – 5mm from the ground Connect wires from line sensors to the breadboard so they can be monitored and controlled by the Arduino UNO (Vcc – 5V, GND – GND and OUT – pin 3 or pin 5 PWM on the Arduino) Modify the program on the Arduino so it can accept the outputs of the line-sensors, determine outcome and output commands to control the rotation of the wheels Load the program to the Arduino and test the robot using already made board with pattern of black lines

Extension Activity: Addition of two antennas in order to transform the robot in a light seeking vehicle. We can connect 2 antennas to the robot. Each antenna has an LDR at the end connected as the diagram illustrates below. When there is more light hitting the voltage read in the Analog pin increases. The idea is simple. If the difference between the absolute value of the two LDR readings is smaller or equal than a pre-tested value d, then continue moving forward (the value d has to be found through experimentation). Else, if the reading from LDR1 is smaller than the reading from LDR2, then turn right. Else turn left. The pseudo code for the main loop would be the following: if (|LDRVal1 - LDRVal2|<=d) { // continue moving forward } else if (LDRVal1 < LDRVal2) { // turn right } else { // turn left }
