An Arduino project implementing a security alarm system featuring PIN code access via a 4x4 keypad, status updates on a 16x2 LCD, motion detection using an HC-SR04 ultrasonic sensor, and ...

This project was for an engineering design class at the University of Houston Clear lake. There were also two other people working on this project along side myself. All parts were bought on Amazon.

Using motion detectors and an Arduino you can trigger lights, fans, or even an pneumatically controlled cleaver-wielding clown to help add your house to the “if you dare” list. There are ...

Motion detection ... The PIR sensor works on 5V to 12V power supply. But it can also be powered by 3.3V pins of the MSP430. To learn more about PIR sensor, follow the link and also learn how PIR ...

It is likely that many of us will at some time have experimented with motion detectors. Our Arduinos ... a different way to detect motion with an Arduino, he’s polling an ADC pin with a simple ...

They are designed to detect motion within their line of sight and are affected by physical barriers like walls. Connect the PIR sensor's VCC (or +) pin to the Arduino's 5V output. Connect the GND (-) ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion ... and Arduino IDE compatibility. The code is an Arduino project for the Digispark Attiny85 to turn on ...

Motion sensor alarms are readily available in the market, but these are expensive. Here is a simple and inexpensive Arduino based motion sensor alarm with voice alert. It can be used for security ...

In this article, I have added three sensors with Arduino UNO and user can choose the required sensor with the help of keypad. Hi there ... The real-time PIR sensor in Proteus senses the motion of a ...
