Re: IS THERE A SOUND SENSOR IN APP INVENTOR 2?

[TimAI2]

Why not use the pedometer/accelerometer ? If the user is wearing the device....

[SteveJG]

You might use  the Sound extension  http://appinventor.mit.edu/extensions/   for capturing a noise.   Your user must either whistle or grunt after each pushup probably.  You will have to experiment.

Cannot wear the device?  If the user does not have his/her Android in his/her pocket or hands, how can you use the pedometer and accelerometer etc. (the pedometer is a special case of the accelerometer); both use the hardware in the device to elicit a response.

Hi Sauroo

I'm not sure if I can wear the device

You can literally wear the device on your arm using a smart phone fore arm/upper arm strap - like a watch strap, little bit bigger and intended for people jogging etc. Check out eBay for example.

Regarding jumping jacks,

maybe there is a distinctive wave form

that can be sensed by gravitational/inertial/centrifugal force / time

on a wrist-mounted phone?

[Abraham Getzler]

is there a way to use a gravitational/inertial/centrifugal force sensor in app inventor?

That's the accelerometer sensor.

I would start at
