Check out this diy timer project for your gym made with Arduino!
This project is a good beginner Arduino project. I wanted a digital timer in my gym that counted up from 00 to 60 seconds and reset. Since I had a spare Arduino Nano and a dual 7-segment display (rescued from a guitar effect pedal) I decided to build my own instead of driving to Wal-Mart.
If you are not interested in the details and just want to see the result, check out the video below. If you watch more than the first 10-15 seconds then you should seriously consider getting hobby. 😉
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
