Sl.No Name Links Description
1 Somashekhar M. Kinagi Lap Timer and Counter In this article, they built a mechanical lap timer and counter. Which displays the best lap time, current lap time, display total laps traveled, they have used IR sensors for it.
Paper Currency Counter In this article, they have built a mechanical counter to count the paper currency notes and calculate their amount, by sensing the paper currency using Color Sensor and Arduino.
Timing Circuit for Production Line In this article, they built a mechanical timing circuit for a production line for keeping a consistent machine running rate, by using microcontrollers.
2 Divya Goudar 1.https://youtu.be/rZCSUzSnQOI The video has a mechanical counter machine that is used to count the number of objects (marbles in the given example ), it is made using gears of different teeth sizes which are made of cardboard and the output is also a simple gear driven wheel that displays count based on the objects.
2.https://youtu.be/foLId13WiBA It is an automatic note counter machine made of an old printer, Arduino mega(configured to increase and display the count in LCD display sheet), LCD display sheet, IR sensors, motor, control board configured for the requirement.
3 Sanjana Naikar 1.https://www.youtube.com/watch?v=MQAUKxq54ow This video explains how to make an automatic counting machine using Arduino.
2.https://www.youtube.com/watch?v=rjWfIiaOFR4 How mechanical counters work. Explaining the carry gear mechanism used in mechanical counters. Mechanical calculators also used this carry gear mechanism.
4 Tejas K L 1.https://grabcad.com/library/mechanical-counter-2 Brain law's mechanical counter
2. https://www.youtube.com/watch?v=Kuf_QTLFE30 Mechanical Rotary counter
5 Vineet. V.D 1.https://youtu.be/_0bj6JidT74 This video from youtube shows how a manually handled mechanical counter machine is built using cardboard and gears of different teeth sizes. The same can be used in quiz contests and many such events.
2.https://youtu.be/CKuweM0YKtQ This video shows an automatic counter using infrared rays module that has an emitter that emits infrared rays and an Arduino module that is configured to increase or display an increase in count in an LCD display that is connected to the Arduino module if IR rays are cut by any object.
3.https://youtu.be/MgEVgjRy184 This is an automatic counter that has an Arduino nano configured for an ultrasonic sound sensor module(that directs to increase a count when the waves are cut by any object), the same Arduino board is connected to an LCD display that displays the count.
