Legacy PCB. TBA.
Project 5. Design Sessions. Your final ER prior to Christmas is to include a comprehesive review of your introductions to EAGLE and ViaCAD. Under Heading 2 styles (either EAGLE of ViaCAD) in the order you explored each application, document your three design classes within the section subheadings: Purpose, Procedure, Media and Reflection. You are NOT required to make a video for this Report, but the text and graphic support will be, as I mentioned, comprehensive. Here are the design projects each group was asked to develop,
|7-Segment Tester||HC-SR04 Mounting Bracket|
|H-Bridge Motor Shield||Stepper Motor Mount|
Project 4. MatrixMadeEZ. For his PCB project in Grade 11, Hugo R. (ACES '19) imagined, designed, and developed a handy PCB that future Grade 11s could exploit to hone their LED matrix software animation skills. We're going to incorporate Hugo's terrific little device into an ambitious standalone project. To assist with your time-management pursuits, I'm strongly suggesting you discipline yourself to stick to the timeline below to enable a successful conclusion two weeks from now, on Saturday November 17.
Parts List for Hugo R.'s MatrixMadeEZ PCB,
The 6-pin right-angle male header will allow your device to be mounted vertically in your breadboard, driven by your standalone Arduino. Make Hugo proud.
Project 3. Shift Register - Bargraph. When Tim Morland (ACES '18, Queen's Eng '22) was in Grade 11, he designed the adjacent output PCB based on the 595 Shift Register and a bargraph. Your toolkit contains the SN74HC595 IC, a 16-pin IC Socket, and a 10-LED red bargraph. The remaining parts, a 5-pin right angle male header, 330Ω 8-pin bussed resistor network, and Tim's PCB, will be provided to you.
You are asked to create a unique and interesting prototype that employs Tim's Shift Register-Bargraph output device.
In addition, just as James Lank dipped into his toolbox and incorporated the LCD screen into his previous ASCII & Buttons project because he was intrigued to discover its potential, each of you is required to do the same. Identify a part you have never previously used and combine it with this Shift Register-Bargraph output device in a meaningful way.
Finally, one shortcoming of this device is that there are 10 LEDs in the bargraph but only 8 outputs provided by the onboard '595 shift register. It's kind of like a packs of hot dogs are sold in dozens but the buns, in packs of eight. This is not good but it clearly presents an opportunity for the creative amongst you.
Your mark will be based largely on how creative and how DIFFERENT yours is from everyone else's and how potentially USEFUL your application could be. Give it some deep thought and push yourself hard your efforts could possibly form the basis for a future ISP. I'm looking for trailblazers this weekend, not followers.
Again, for the engineering and for the unique design and creativity.
Project 2. ASCII & Buttons. Time to let the horses run. We've reviewed the Arduino's recognition of the ASCII characters and it's ability to read (properly conditioned) button input. For your second project I want your imagination to take center stage in the pursuit of a creative application involving button presses, ASCII characters, some form of manipulation/processing of the two, and its display.
The -rating of this project is based on for the engineering and for the unique creativity your project will project (how's that for phrasing!). Standard ER sections apply with heightenend awareness of the video constraints now in effect (no music, stable camera and components, no spelling errors in the video titling, and not too many Persian carpet backgrounds)
Since many of you will be pursuing your driver's license in the near future, the focus of this first summary is the design, careful soldering, programming and thorough testing of a Traffic Light. For the assembly aspect of this project you will solder one each of a green, yellow, and red LEDs onto the section of stripboard you have been provided with. NOTE: The stripboard only has three strips. The placement and orientation of the LEDS is tricky and you must give it some DEEP THOUGHT if you're going to be able to program it so it operates correctly. Take care as there are NO replacement parts. A three-pin right-angle header, soldered at one end, will enable your device to be inserted directly into your Arduino's female port pins (see photo) Be sure to document your soldering of the device through media acquisition that you can include in your report. For the testing aspect, you will include media as well as a simple sketch based on our discussions in class. The fully documented sketch should cycle through the LEDs continuously with the green and red remaining on for 3 s and the yellow, 1 s.
In your report, include the sections Purpose, Reference, Procedure, Code, Media, and Reflection Heading 2 (or 3) style. A full Parts Table should appear right-aligned within the Procedure section.
