Arduino Nano helps secure your bicycle
Check out the TapLock system, which uses an Arduino Nano 33 BLE Sense to help secure your bike.
It’s featured on the Arduino blog – see here – but comes originally from hackster.io.
With the Arduino detecting tap patterns via an onboard accelerometer, in theory you could lock or unlock the device either via Bluetooth or taps on its enclosure. Note, however, the locking mechnaism has not yet been implmented, but the creators envisage using the Nano’s GPIO pins to electronically activate a locking mechanism.
“Because taps are not necessarily directional, the TapLock’s creators took an average of each accelerometer axis and charted the time between the peaks. After collecting a large sample of data, they used Edge Impulse to process the data and then train a model with an accuracy of 96.4%. This allows the owner to have some wiggle room when trying to lock or unlock the bike.”

Maker and YouTube William Sun Petrus has converted an old 1920’s typewriter, check out the tutorial below to learn how you can transform a Remington portable typewriter into a MIDI controller using a little Arduino programming and hardware with great results.
“William Sun Petrus has done the impossible… well, the improbable and turned his 1920’s Remington Compact Typewriter into a MIDI controller! Armed with a typewriter, an Arduino Nano and some standalone programs – he’s made it possible use the hammer contacts with the “live plate”, which will send a signal to the Arduino which will, in turn, send MIDI. He’s created a tutorial and run down of the setup to show its inner workings as well as an extended cut of the original video. The Arduino code is also hosted on his GitHub page, if you’d like to finally put to use the 1920s Remington compact typewriter you have lying around. “
