Use to show the value of the light sensor in a way where a stage character (a panda) speaks the value out. Does anyone know what I should put into y code to allow this to happen? The bit that sorta says "if light sensor 1 reads value 0, trigger sound1'. Magic Light Cup modules are easy to Interactive Technology Division developed a can and ARDUINO interactive modules, PWM dimming principle is to use the principle of two modules brightness changes. This isn’t always the case, as engineer "Tech Martian" illustrates in the video below, using a photoresistor and RGB LED along with an Arduino 101 board. A simple light sensor can be built using a photoresistor and Arduino UNO board. Tilt switch module and a digital interface, built-in 13 LED build a simple circuit to produce tilt warning lamp 13 comes with digital interfaces of the LED, the tilt switch sensor interface to access digital 3, when the tilt open Off sensor senses a key signal, LED lights, otherwise off. It is adapted to human eye responsivity. The overall concept is that you will generally have a microcontroller (like Arduino) hooked up to sensors (like soil moisture) and actuators (like a water valve). We've been making the PulseSensor ever since.
