DESK OF LADYADA - Long Weekend for Hacking! ESP32-S2 CLUE, BLE sensors, E-Ink displays & clock & SD
168We had a lot of time for making, hacking, and tronix this weekend. Fueled up with some tasty Chinese food, we tore apart a Mi Home-compatible BLE sensor and E-Ink clock, added 7-color ACeP E-Ink support to our Arduino library, tried out some SD-card-on-a-chip samples, and even started working on an ESP32-S2 WiFi CLUE board (our last CLUE was designed almost exactly a year ago and was nRF52840 based)
The Great Search - 74 Logic Chips
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. Lets 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!
