Electrical Output and Bluetooth

I think sensor boards need to have an electrical output. Then, you would be able to control the voltage coming out of it and connect things like light bulbs or electric motors.

Also, sensor boards should be able to connect via Bluetooth. This would be good for many reasons:

1 No more long cables,

2 longer range,

3 going with the electrical output idea, you could make little robots that could drive around controlled by your computer, and report back the sensor values.


I hope the Scratch Team will consider these ideas.   smile  smile

Re: Electrical Output and Bluetooth

The problem with electrical output is that somebody could overload the system and start a fire quite easily - especially somebody who doesn't know what they're doing. And Bluetooth would hike the price of these boards up extraneously (my new favourite word!). They're good ideas and could potentially be very helpful, but I don't think they're practical.

What do you mean? It wouldn't put out a lot of electricity at all, maybe 1 to 2 volts, just enough to run an electric motor or something.

Also, Bluetooth isn't all that expensive, and it would revolutionize the sensor board (okay maybe not) but it would really help.

Well, I guess your first argument is reasonable.

The problem with Bluetooth is, well, is it really necessary?

That's a good point, but yes, for some of my projects, it would be really nice to have Bluetooth for it. And think of the possibilities! you could have your sensor board in another room and still monitor it's sensors.

^^ Scratch Boards are powered through a USB port.
^^USB ports are limited to 5 volts

Re: Electrical Output and Bluetooth

How about ZigBee?
ZigBee module is more cheaper than Bluetooth and popular at physical computing.
There are many applications of robotics and sensing using ZigBee.

I guess we can extend PicoBoard emulator on Arduino with ZigBee.

Your right the scratch sensor board is already good enough

I don't think so, honestly I don't think it's worth the price. I hardly ever use mine and even when I do, It feels limited.

I know the price $60,$70 its still worth it

I know. It took forever for me to get mine, and a few days after I started using it, it seemed kind of limited.

Did you get the slow shipping? probably. thats what im using and i hope that it will ship from 2-4 weeks and not longer.

LOW VOLTAGE!! You don't need much electricity to control an electric motor...
