I was at Radio Shack the other day and came across a nice little gem. This RFID reader is selling on clearance for $8, when it normally goes for $40. It comes with two tags. The ones I got are a credit card sized version, and a disc version. I couldn’t resist, so I bought it and spent 20 minutes getting it working with my Arduino Decimilia (yes, yes, I know it’s outdated). Be warned, these are only sold in stores and are on clearance, so call your local Radio Shack before stopping by to pick one up. You can buy the more expensive ones at the Parallax web store. You can buy Arduinos in many places, including Amazon.
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.
