To be more motivated during exercise, Nikolas has decided to make a Smart pull-up bar using an Arduino Nano which, when you start exercising, will start playing music and will give it a Tic Tac at each set period of time as a prize. A laser diode and photoresistor located at opposite ends of the…
In this project we will see a table football that detects the goals from both doors and displays the result on an android tablet. The circuit is very simple: an Arduino Mega detects goals through two photoresistors and two laser diodes. Arduino sends the necessary data to the Android tablet via the USB connection. More…
Have you ever wondered why smartphones are called smartphones? Because they are smart, right? They do some jobs automatically, intelligently. This is the short answer. For example, mobile phones have an automatic brightness control system, which is very useful. But for unknown reasons, computers don’t have an automatic brightness control system. To change the brightness,…
In this project we see how to build a dual axis solar tracker with photovoltaics. The photovoltaic itself will power the tracking system, so no external power source is needed. To track the sun, we used four LDR sensors, Arduino UNO compares the data provided by them to rotate the panel in the direction with…
Here is an easy tutorial about creating a diy domotic assistant for your home. It allows you to collect many environmental values from different sensors and shows them on a web page. It is also Telegram compatible. More info Buy Fishino boards on our store!
With a DVD laser pick-up, an Arduino Uno, a laser, and an LDR, Instructables user “Venkes” has managed to create a DIY Laser Scanning Microscope (LSM). It’s capable of 1300x magnification and attaining a resolution of 65,536 pixels (256 x 256) in an area of .05 x .05mm. A laser microscope works by shining a beam of light on…
