Enough with the learning let’s get our hands working and build a custom ICSP cable to program/bootload an Arduino, an ATMEGA328P (chip used in Arduino UNO) , or any other AVR microcontroller. Things ...

This Arduino ICSP programmer has been made from Alumide, a strong plastic with aluminum fibers. The cover is made from translucent POM, illuminated by three rings of in total 27 LEDs.

The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-cathode module containing four 7-segment LED numeric ...

The Giga Display Shield (plug-in board) might fit the bill. It adds a 3.97inch 480 x 800 RGB touchscreen, digital microphone (MP34DT06JTR by ST), six-axis IMU (Bosch BMI270 inertial measurement unit), ...
