Unfortunately I've only a few parts for the arduino. Can you suggest me ideas for projects with these parts.
a few LEDs, a piezo element, a few 555 ICs, an LM35 temperature sensor, a few LDRs, IR recivr ICs (TSOP),
I'm thinking of doing the following
- Trying capsense, 2)Make knock detecting door lock and playing tunes with the piezo element, 3)displaying temperature on computer using processing, 4) make processing read twitter feed and send them to arduino for doing physical actions, 5) Connect an old keyboard I have to arduino, 6) Decoding TV remote commands and doing something like lighting LEDs
