Today I would like to present you my touch sensor module prototype for littleBits kit. I needed this little module to create an interaction between littleBits and Bare Conductive paint for my workshop about wearable tech for children. I started considering the example shown here. Then I made some little changes.
For a prototype of this specific touch sensor you will need:
- 100µF/12v capacitor (at least);
- 555 timer IC;
- An LED to test your sensor.
- A breadboard;
- An Arduino to provide power;
- A crocodile clips;
- Bare conductive paint pen.
Here you can find a detail of the breadboard:
(The yellow jumper is the one connected to bare conductive paint via crocodile pin)
In the next few days I will upload the examples of the final version soldered on a micro board that will be embedded into littleBits circuit.
This is how the bit will look like, feel free to download this image:
I hope it will be useful for you!
Stay tuned for further details!
