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!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
