Introduction to Arduino and programming . There is also a “quick walk-through video” of this tutorial. We will build a distance meter in this tutorial. It uses an ultrasonic distance sensor to sense the distance to an object nearby. It consist of the following steps: 1. Connect and test the OLED display Before you start connecting … Continue reading Tutorial: build a distance sensor with an alarm
Most 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!): Download the sketch: oled_display_countdown_start_button.ino Full simulation including breadboard on Wokwi: This will countdown from 10 to 0 in ten seconds after … Continue reading Countdown timers and executing tasks in parallel on an Arduino
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
