Con una resistencia LDR podemos crear un thermín, primer instrumento electrónico de la historia tutorial paso a paso buzzer + resistencia LDR

In this activity, students investigate water turbidity and how this can be monitored over time using electrical components.

Automated T-Rex player using arduino and python.

Aquí un sistema de sincronización de dos puertas de luz separadas por una distancia. Cada puerta de luz consta de un módulo #láser en un lado, y una #LDR en otro. Al cortar el haz de luz en este caso, se calcula la velocidad de un cuerpo. https://t.co/s3ewObnLbV…

The Light Badge: The Light Badge is an electronic kit which utilizes an LDR( light dependent resistor) to detect lowering light levels and light a LED once it gets dark.This is a great example of an LDR in action.This PCB can be used as a Wearable device.

Capture the flag can be fun, but Karel Bousson has put a new spin on the game that allows you to compete against neighbors over who can keep a single item — a modified tool case — in their possession the longest.



The box contains an Arduino Mega that…

Do you love to bowl? Are you still unable to do so due to the pandemic? Then this project by high school engineering teacher Laine Schrewe is right up your alley!



This rig features a 5½ foot (1.68 meter) lane made of MDF, along with ball bearings used…

As a fun weekend project at home, Arnaud Atchimon and his son came up with a DIY laser blaster game comprised of a 3D-printed shooter and target setup.



Both devices are controlled by an Arduino Nano, and when the gun is powered up, you can either have…

How do we know that planets exist outside of our solar system? While too far away to observe directly, with extremely sensitive equipment like the Kepler space telescope it’s possible to detect changes in light as these exoplanets pass in front of a star.…

Like most of us, Joey Cumeras Khan has been stuck inside for the last couple of months. As a foosball fan, this not only meant plenty of time to play with his fellow housemates but also the perfect opportunity to tech out his table with an automated scoring…

Nowadays, a lot of video calls are made via Watsapp, or face-call or whatever you're used to on your side of the world. These tools are great since they're simple enough that they allow an older person to use them easily. Nevertheless, if we want…
