This project combines a Raspberry Pi, USB SDR (software-defined radio) receiver and PiTFT display to examine wireless signals and protocols. With the addition of a USB battery bank, this could be the start of a portable RF “sniffer.”
Periodic updates to the Raspberry Pi operating system sometimes break previously-published tutorials; this was one such guide. We sat down with it and patiently worked through some fixes, and it’s back in action now! Best part is that the setup is a bit simpler now.
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.
