The circuit is infact a dark activated switch measures the ambient light level and will enable the system only when ambient light level is below a threshold value. Here an LDR (Light Dependent ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I ...

The code is an Arduino project for the Digispark Attiny85 to turn on a light source when the PIR sensor detects something. Note that after powering the PIR sensor module, it needs about 10 to 60 ...

PIR motion sensors use infrared light to detect movement. Light is emitted and the sensor will trigger if it can't detect its reflection, enabling a basic form of motion detection based on the ...

We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. Last month we saw [Udo]’s blinkenlight shield that can be used as a lin… ...

Present consists of just a PIR sensor and Arduino in a 3D printed enclosure to snap onto your monitor. ... some white LEDs, a light sensor, and the original blinking red LED.

It will also prepare the user on how to successfully hook the Velostat up to an Arduino and how to code for it. This module can be used from K-6. Materials not included in Arduino kit: Velostat ; ...
