This was implemented using a laser, LDR (light-dependent resistor), 16x2 LCD, LoRa modules and Arduino Nano. The lap timer can be used to find lap timings for a circular track as well as for a ...

Also, this module focuses on how to time events using Arduino’s built-in function millis (). It is designed to be used with a pre-built ramp that can be provided if used in a classroom environment.

An Arduino Uno and the relays for the laser and fans sit on the MicroSlice’s bottom platform, and two EasyDriver motor controllers sit above them on the next layer.

A portable Arduino timer. Has two different modes: one where it counts up, and one where it counts down. The user interface is done through an LCD screen, and the input comes from 2 push buttons. The ...

Arduino enthusiasts and makers looking for a project to keep them busy over the next couple of weekends might be interested in this Arduino flying start lap timer, which has been featured over on ...

This project is also available at Max Imagination’s Workshop. Welcome, fellow makers! Today, we're diving into the world of productivity and time management with a hands-on project – the Arduino ...

AnalogWrite uses the various timers on an Arduino to put out a pwm waveform – with 1/256 (ish) resolution. And it offers 0% and 100%. This is naturally-available with the timers that the Arduino IDE ...

“Arduino Self-Timer” project presented here is a low-component count 60 seconds countdown timer. It can be powered from a 9V compact battery or suitable Arduino AC mains adaptor. Working of the ...
