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): 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 stepper motors you do need a … 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
Introduction to the Arduino BLE Nano
The BLE-Nano as sold here is a combination of a traditional Nano with a Bluetooth BLE module, based on the CC2540 BLE bluetooth chip. The Bluetooth module is directly connected to the TX, RX pins of the Arduino (pins 0 and 1). There is a troubleshooting section further down on this page! This is the … Continue reading Introduction to the Arduino BLE Nano
Using an Optical (IR) sensor with Arduino
This short tutorial introduces the Optical (infrared) distance sensor (Sharp GP2Y0A21YK0F). It is assumed you have installed the Arduino IDE and have some basic understanding of using electronics and wiring a breadboard. If you want to learn more or if anything is unclear, check out this extensive tutorial. Although in this example we use a display, you can … Continue reading Using an Optical (IR) sensor with Arduino
Use an OLED Display with Arduino
Information on how to use an 0.96 inch OLED Display (128*64 pixels) with an Arduino. This is an i2c module, which makes it easy to connect as it has only 4 wires. It is assumed you have installed the Arduino IDE and have some basic understanding of using electronics and wiring a breadboard. In addition, … Continue reading Use an OLED Display with Arduino
Sounds and music with Arduino
This article highlights four different ways you can make sounds with the Arduino or play music. It starts with the easiest one: (1) adding a small buzzer, then (2) a standard loudspeaker, then (3) using your smartphone as the speaker via an connected app. It ends (4) with using an MP3 module. A tutorial which … Continue reading Sounds and music with Arduino
