A lamp holds great importance in once life. They are the source of light and make thing visible to you. When light is emitted from a lamp, it travels in all direction and after striking from a surface it comes to our eyes and the object is visible to you. The discovery of electric lamp was made by Humphry Davy (an Englishman) in 1809. An electric lamp can be used in multiple ways. It can be used as a study lamp, a table lamp, light bulb (a kind of lamp ) or a emergency lamp. Previously lamps were made from electric bulbs and CFL but now a days lamps are being build by LED.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
