That video is great/helpful. The other issue I’m having is how to I find a website/resource that I can use to record audio files to link to keyboard commands? I have NO idea where to start with that. I came up with the idea of how to use the Makey Makey, but I don’t have the knowledge or background to know how to go about getting it to come to life, so any help would be appreciated!November 12, 2020 at 8:24 pm #10683
I use a free program called [Voice recorder]([https://play.google.com/store/apps/details?id=com.media.bestrecorder.audiorecorder](https://linkcheck.neilsquire.ca/?url=https%3A%2F%2Fplay.google.com%2Fstore%2Fapps%2Fdetails%3Fid%3Dcom.media.bestrecorder.audiorecorder&id=88aa&rcpt=zeek%40neilsquire.ca&tss=1608063167&msgid=e5e952db-3f11-11eb-aed7-174763e477d7&html=1&h=d30121b0)) on my phone, but you would also need a way to tell the Makey Makey what to do with the sounds when a switch is pressed.
I think(but I’m not an expert) Scratch would work best for this. In the workshop we covered this at 1:27:11. I will DM you the link again so you can watch.November 12, 2020 at 8:24 pm #10684
You can record sounds in Scratch and use keypresses to play them! It might sound hard, but it is actually pretty straight forward! https://makeymakey.com/blogs/how-to-instructions/lesson-five-code-your-key-presses-in-scratchNovember 12, 2020 at 8:24 pm #10685
I can attest to this-it is SUPER easy to record-I played with it over Xmas break!
I noticed that depending on the sound you record it sort of cuts the high and low end(in music for example) but it works well for recording voice.November 12, 2020 at 8:24 pm #10686
THank you! This is what I’ll definitely have to try once I get the electronics part to work…November 12, 2020 at 8:24 pm #10687
Can someone explain why it works like this (alligator clip on conductive tape on cardboard, pressing down on playdoh) but then doesn’t work when the 3D tactile symbol is placed on top of the playdoh and pressed down?![Makey Makey Project 1|375×500](upload://aMd2qw4QdesSG1Igt0WY5EIjo2q.jpeg)November 12, 2020 at 8:24 pm #10688
Doesn’t work like this. Should I try bubble wrap instead of playdoh? I have NO idea what I’m doing wrong! I was also thinking I should maybe do a second piece of cardboard on top of this with cut outs for the tactile 3D shapes. However before I go all crazy I need to figure out the circuit part.

What’s likely happening is that the plastic material (probably PLA) of the tile isn’t very conductive – it doesn’t let enough electricity pass through it.
When the playdough is pressed with the finger, that connects the loop of the circuit: tiny amount of electricity can go from the Makey Makey, through the wire to the alligator clip, into the tin foil, through the playdough, through the finger and then through the body back to the wrist strap and back to the Makey Makey.
When the tile is added, the path is blocked.
There are some suggestions earlier about ways to make the tile more conductive (e.g. changing the material, coating it in something).
Alternatively, you would need to look at making more of a switch that closes the loop through the mechanical action of moving/pressing the tile rather than being part of the circuit.November 12, 2020 at 8:24 pm #10690
I replied in another thread about this, but we have a lot of resources on our blog for making your own switch. We did try to make a switch during our workshop but there was a ton of info that night!
Here is a guide that shows different ways a switch is open and closed with Makey Makey https://makeymakey.com/blogs/how-to-instructions/lesson-eight-crafting-and-designing-switches
Here is a guide for just making cardboard buttons-https://makeymakey.com/blogs/how-to-instructions/makey-your-own-exit-ticket-or-data-tracker and the 3d printed object can be on top in a switch like this. (PLA is not conductive, so putting it on top of the play-doh won’t work. (Unless you did something like bring conductive tape from the object to the top for you to tap. AT that point- you wouldn’t really need the Play-doh anymore!)
@valill sorry for the delayed responses! Last week was crazy for getting back to work and the kids virtual schooling- and all the news!November 12, 2020 at 8:24 pm #10691
I am guessing you are using the playdoh as a means to create physical resistance (to challenge the students muscle/ strength etc)?November 12, 2020 at 8:24 pm #10692
I wanted to let everyone know that thanks to my 14-year-old son’s assistance, my project is now working. He helped me with the audio files in Scratch (which he claims was a very simple coding activity lol). My original idea (as posted here) did not work. So I then I tried to make it with 6 individual cardboard switches (like the ones we made at our workshop in Dec), and that didn’t work either. My son offered me another solution…and of course that one worked. The device doesn’t work exactly like I had planned, but it is working. I’m all ready to go for Tuesday!November 12, 2020 at 8:24 pm #10693
Physical feedback that they pushed the symbol (since they’re for students with visual impairments)November 12, 2020 at 8:24 pm #10694
This didn’t work. I did it as 6 individual switches made exactly like how we did it in December. I used aluminum foil etc. WHen I pressed down on the symbols they didn’t work. I found another solution that works. THanksNovember 12, 2020 at 8:24 pm #10695
