Bluetooth for Arduino vs Shift

Do you want to control via bluetooth the Arduino project you built? Let your iPhone or iPad be a remote control for any micro-controller with a bluetooth module. Run the app, search for your bluetooth module and connect. Once you are connected you will be able to send your own commands to your Arduino board using the keyboard or some fancy buttons

Start your HIIT workout in 3 taps. No setup friction. No clutter. Just a clean, fast interval timer built for people who actually train. Shift is a purpose-built HIIT timer designed for speed. Set your work intervals, rest periods, and rounds — then go. No account required. No ads. No bloated feature set. WHAT SHIFT DOES: — Custom interval configuration: work time, rest time, rounds, sets — Tabata, EMOM, and custom HIIT protocols — Clear audio cues and haptic feedback so you never miss a transition — Visual countdown optimized for glanceability mid-workout — Minimal UI that stays out of your way BUILT FOR: — Home workouts with no equipment — Gym training between sets — CrossFit-style timed circuits — Tabata protocols — Any interval-based training WHY SHIFT: Most timer apps are either too simple (just a stopwatch) or too complex (10 screens before you start). Shift sits in the sweet spot — fully configurable but fast to start. Designed by Credes, a product studio that ships tools people actually use. Start training. Not configuring.
