Pokemon GO has shown us that people can really go crazy over running around our cities bent on catching imaginary animals. It has also shown us that people are going crazy over chasing down said animals at all hours of the night and not always paying attention to what is going on around them. This is amplified when we are talking about children that are having a blast literally trying to catch them all. Build a safety light that's also a lovely way to show team spirit with this no-solder project!
Add Internet to your next project with an adorable, bite-sized WiFi microcontroller, at a price you like! The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well. While this chip has been very popular, its also been very difficult to use. Most of the low cost modules are not breadboard friendly, don't have an onboard 250mA 3.3V regulator or level shifting, and aren't CE or FCC emitter certified....UNTIL NOW!
The Adafruit PiOLED is your little OLED pal, ready to snap onto any and all Raspberry Pi computers, to give you a little display. The PiOLED comes with a monochrome 128x32 OLED, with sharp white pixels. The OLED uses only the I2C pins so you have plenty of GPIO connections available for buttons, LEDs, sensors, etc. It's also nice and compact so it will fit into any case.
Use Circuit Playground to make a classy seashell necklace that goes with every outfit. Change colors and brightness on the fly with a click of Circuit Playground's onboard buttons.
