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. 😉
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
