The Great Search: 74 Series Logic Chips #TheGreatSearch #DigiKey #Adafruit @DigiKey @Adafruit
The Great Search is a new series of videos focused on searching the Digi-Key catalog to narrow down to the parts you want to buy. This week (video):
While working on our WiFi CLUE board, we realized we needed a little logic circuitry to put the board into a bootloader mode when both buttons are pressed on power-up. How to do that? A simple NOR gate will do the trick. There’s lots of times that a little logic circuit will help glue more complex parts together.
Let’s check out how to find 74 series logic chips on Digi-Key and tricks and tips on picking the right part & family from the massive selection options!

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.
