Big Clive Reverse Engineers a Simple LDR Halloween Toy Circuit
Big Clive videos are always fun but this one especially so. In it he reverse engineers a simple circuit from inside a Poundland crow bird prop sold for Halloween – someone moves within proximity of the toy and it begins crowing, like a crow. Big Clive shows how the circuit consists of not much more than a LDR, some resistors and capacitors, sound module IC (underneath the black blob) & speaker – in other words this circuit can easily be ported to other purposes! (The speaker transducer is also a simple and effective design – shown right at the end of the video.)
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
