The ‘555 Based Motion Sensing Night Lamp Kit‘ from electronut looks like a simple enough project for anyone exploring 555 timers. The transistors, capacitors, and resistors are all common components and through-hole PCB designs are provided. The project could easily be modded to fit into a toy or other enclosure, or extended for more functionality. Let me know if you build this or mod it in any way – 555 timers are great starter projects!
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.
