As its name suggests, the CO2 Display project is a small CO2 gas sensor to be plugged into USB to easily track indoor and outdoor pollution.The CO2 level is displayed live, but it is possible with the small application provided in the documentation to generate capture samples in image (in png format) and in list […]
A while back I saw an EMF (Electromagnetic Field) Detector at makezine.com that used a led bargraph. I decided to modify it to use a 7-Segment LED Display! Here’s my project. Sorry I don’t have any pictures of it in use. Hopefully I can post some soon. Credit goes to Aaron ALAI for the original
We all have seen different kinds of mood lamps & RGB light, most of them have some buttons or a remote to interact with them, but we thought of making a Gesture Controlled RGB Desk Lights which can change its colour only using a simple swipe gesture as a trigger. This is an interactive art project made
In the spring every year, we have a group of robins who start making nests around the house. We also have lots of windows in a patio area that when the robins see their reflection they think it’s a rival bird. They attack the windows repeatedly for months. They land on the chairs, railing and
Let’s create a simple Gas Detector connectable to WiFi. The gadget would offer: web UI including gauges for LPG, CO, Smoke simple data handler returning values in JSON capable of regularly sending data to ThingSpeak server and obviously triggering laud alarm if threshold of dangerous concentrations exceeded. We would need following components: NodeMCU with ESP8266
N.B. this is new and still being tested. This sketch demonstrates several examples of single-channel filters for processing sensor data. The filter functions are purely numeric operations and not dependent on any Arduino-specific features. This supports offline testing, as they can be compiled for debugging and evaluation on a normal desktop computer. The code is

Hello there! I hope you all are fine and in good health. This instructable is about making your own current sensor that is compatible with Arduino and most other widely popular microcontrollers. This project features a compact design and an all SMD component based circuit, making this sensor module very compact for it’s range. This
Sometimes you want everything in the program to stop while a given condition is true. You can do this using a while loop. This example shows how to use a while loop to calibrate the value of an analog sensor. In the main loop, the sketch below reads the value of a photoresistor on analog pin 0 and

This project will show you how to create a computationally enriched puppet that can detect magnetic fields. The puppet (who I call Compy) has two very sensitive GMR analog magnetic sensors that are located in her beak, these sensors are read by an Arduino Nano that actuates a 3×3 haptic display (Figure 3) based on
