Generally, any activity out on the water is more dangerous when done at night. Hazards are less visible, and it can be easy to get into trouble. [Xyla Foxlin]’s party canoe can’t help with that, but it does look the business after dark. The canoe is made out of fiberglass, directly formed onto an existing canoe to make […]

Adafruit has this week announced the availability of its new LTR390 UV Light Sensor and is one of the few low-cost UV sensors available on the market. Offering both ambient light and UVA sensing with a peak spectral response between 300 and 350nm. The sensor is perfect for projects that need to measure how much
Adafruit LTR390 UV Light Sensor now available Continue Reading
I was inspired by the cute Frankenbot papercraft, so I thought why not make it truly alive by giving it some blinking lights and sounds effect. Here is the plan: – Connect 2 LEDs for the eyes (different colours of course) and only one eye can be on at a time – Connect 3 LEDs

Problem: my dad is registered as deaf and my mum is hearing impaired and due to this they often find it difficult to hear the doorbell. This could be a problem suffered by many others as well. They bought a flashing light doorbell to help them with this (a small box with a light that

Let’s learn how to read a photoresistor, a light-sensitive type of variable resistor, using Arduino’s Analog Input. It’s also called an LDR (light-dependent resistor). So far you’ve already learned to control LEDs with Arduino’s analog output, and to read a potentiometer, which is another type of variable resistor, so we’ll build on those skills in this lesson.

For this project you will be creating a device that is capable of opening and closing window blinds, both automatically and manually (via a push button), based upon a time schedule and sensor data from a light dependent resistor. In addition, this device will be able to display messages to the user. I personally embarked

Exactly a year ago (February 2020), James’ wife wanted to expand her plant growing setup in the house. This included a bigger, larger, taller plant growing area AND the need for more lighting. BINGO! The seed for the Idea was planted. After an exhaustive market research, not able to find the product that we had

The need for such modernization arose when used in remote buildings located near a country house.Adults and especially children turned on and forgot to turn off the lamp. As a result, the batteries drained quickly. I decided to replace the incandescent bulb with more economical and efficient LEDs and limit the lamp run time. The

So much of our lives is spent making choices. Cut down on that time by making your own “Don’t Make Me Choose” project. This project uses the lights on a Circuit Playground to point to a specific item you have listed on the whiteboard. This project is great for choosing a date night activity, place

Swedish and Chinese scientists have developed organic solar cells optimised to convert ambient indoor light to electricity. The power they produce is low, but is probably enough to feed the millions of products that the internet of things will bring online. For more information see the IDTechEx report on Energy Harvesting Microwatt to Megawatt 2019-2029. As the internet of things
