Rev 2.5 – tidied up the 3D printed parts and updated the plug connector to a common PCB unit. Rev 2 – ultrasonic “button” replaces manual push-button. Pushing a button is so old fashion, particularly when I’m already using an Ultrasonic sensor. Why not use an ultrasonic sensor to activate the can level detector! Rev

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
This Color Detector utilizes an Arduino Uno R3 and TCS3200 color sensor module. Color identification and detection can be beneficial for food-processing units, color printer applications, paint-mixing applications, and other industrial applications such as robotics. This project is designed to identify basic colors (red, green, and blue) that are present in LEDs in a single

Project Abstract I’ve been exploring the idea of creating a robot using Arduino technology for a while now. This project marks the initial phase of this ongoing hobby endeavor. The aim is to construct an object detection system that can be integrated into a semi-autonomous robot in the future. The system employs an ultrasonic range

Don’t let a clogged drain slow you down!Coming back from our vacation, me and my wife were surprised by the water covering the floor of our apartment, and we found out it’s not even clean water, it’s drain everywhere. After clearing the drain and cleaning the floor, I had this question: why don’t we have

The STM1831 is a voltage detector with very low current consumption. It monitors a voltage on a separate input pin (VSEN), which is fully functional even if the monitored voltage goes down to 0 V. In addition, the delay of the output can be adjusted by an external capacitor. Key Features Voltage monitored on separate

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
