Options for additional components and power for the Arduino

What options are there for the use of motors in our project? There are many types of motors. There are 3 basic types (more info): Servo motors Stepper motors DC motors Most light servo motors can be used directly with an Arduino (no motor driver/controller required). For some heavier types and for many DC and … Continue reading Options for additional components and power for the Arduino

Countdown timers and executing tasks in parallel on an Arduino

The examples in this article use an OLED display. Countdown timer example In its simplest form, a countdown timer can be coded like this, using the loop() for repetition (no for- or while-loop needed!): Full example : oled_display_countdown_start_button.ino This will countdown from 10 to 0 in ten seconds. If you prefer to display the number … Continue reading Countdown timers and executing tasks in parallel on an Arduino
