I made the Synthesis ToolKit (SKT) available as Arduino Library. The Synthesis ToolKit in C++ (STK) is a set of open source audio signal processing and algorithmic synthesis classes written in the C++ programming language. STK was designed to facilitate rapid development of music synthesis and audio processing software, with Read more…
A couple of months ago, I described how you can use my Arduino A2DP library to receive music with an ESP32 via Bluetooth e.g. from a mobile phone. I have extended the library and implemented the BluetoothA2DPSource class that you can use to to the opposite and send sound data Read more…
I was looking for an easy to implement solution to control my RC Airplane (that is using a ESP32 micro controller) with the help of a Mobile Application. I decided to use QGroundControl which is based on Mavlink. My project provides the following features: It is available as Arduino Library Read more…
I proudly announce that my Spektrum Satellite Arduino Library has been released with the version 1.0.0 on Github: It features: A Complete Implementation of Official Specification Support for binding using different BindModes Support for receiving and sending of data Input and output are handled via Streams. So you can use Read more…
After my bad experience with this topc I decided to give it another try. I assumed that my issue from last time was that the receiver did not get enough power (after all it was a bad idea to power the satellite from a GPIO pin directly) so I decided Read more…
if you google for “Arduino LED blinking sketch” you might find something like this: #define ONBOARD_LED 2 void setup() { pinMode(ONBOARD_LED,OUTPUT); } void loop() { delay(1000); digitalWrite(ONBOARD_LED,HIGH); delay(100); digitalWrite(ONBOARD_LED,LOW); } (I’am using an ESP32 and therefore I needed to define the ONBOARD_LED because this is not predefined in Arduino.h) This Read more…
I was building a small Remote Control for my RC toys with the help of a ESP32. This Microcontroller is the perfect choice because – it supports enough analog input pins (we need at least 4) – We can use Bluetooth or UDP as Communication Protocol out of the box Read more…
Spectrum Satellite API for Arduino I was working on a small project to implement the Spectrum Satellite Receiver Protocol on an Arduino. The project should work with any type of board (e.g. Arduinos, ESP32, ESP8266 etc) Complete Implementation of the Spektrum Satellite Specification Support for sending data e.g. to build Read more…
It is very easy to control servos with the help of the Servo Library which is part of Arduino. For my tests I was using an ESP8266.to evaluate the following small Servos: 1.5g 180 Degree Nylon Gear Digital Linear Micro Servo 3.7V-5V For Micro RC Airplane – left 1.7g Low Voltage Read more…
I am planning to design and build a 3D printed RC Airplane. To shortcut the “Remote Control” functionality I bought a second hand Spectrum DX 6i that I wanted to use together with a Spektrum Satellite Receiver: These Receiver Boards are quite small and it should be quite easy to Read more…
