Trying to help granddaughter
I hope I’m posting this in the right place, forgive me if not.
I am studying Arduino and bought the Elegoo Super Starter Kit to help me along the way.
I have a granddaughter with high-end autism, they used to call it Asperger's. It makes her very anxious, and she’s having trouble in high school as part of it.
May I ask for a little advice from you kind people?
I would like to build a “Useless Box” to try to distract her over active mind sometimes.
I have been studying the many boxes on here and YouTube and I think I know what I want.
What I would like to do is put a vibrating motor in the head of the doll and have it shake vigorously “in frustration” at a point or two in the cycle.
I’m pretty sure I can do it with an ATtiny85 type board, I only need 3 pins really. Two PWM for the servos and one digital for the vib motor. I know to run the servos and motor off a 9V battery. I have started to read some info on just using the chip by itself to run this thing. Once it’s programmed, that will be it. Your thoughts?
Now, if you don’t mind, some more questions.
Unlike so many posters on the forum, I want my motor to shake. I’ve seen many motors on Alibaba and such that might work. Any of you use a counter- weight vibrating motor? Which one would you recommend?
Can I simply cycle it on and off again with a simple switch command without the use of a shield to control the motor? I don’t need, or want really, speed control.
Is it the usual case for the board to power up from the USB, when it is available, and switch to the 9V when it’s not? The idea is to make the box portable.
Thank you for your time
