This article assumes you have already some experience in creating Java Apps. For instance if you have done the first 2 lectures of the course Application Development. You should also have prepared the DHT temperature/humidity sensor and have a working sketch for it (eg. by completing step 1 and 2 of this assignment, or via … Continue reading Create a stand-alone Java App that displays info from a connected sensor
The Nano BLE 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). This is the pinout of the board: Check out the location of … Continue reading Introduction to the Arduino Nano BLE
An example to control the intensity of vibration using PWM for the Vibration DC Motor Module. For example this model: Connect the module to 5V (VCC) and ground (GND) and the IN pin to any PWM pin of the Arduino. Eg. for an Arduino Uno, this can be pin 3. For an overview of PWM … Continue reading Vibration Motor control
