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…
Quite some time ago I bought some cheap DRV8833 Motor Controller Boards (HW-627) from China and now I planned to use them in one of my projects. I was struggling quite a bit to figure out how this is working. This board is using the DRV8833 chip and can control Read more…
Overview I was playing with the idea to implement a simple Synthesizer for the ESP32.which would play different instruments. The ESP32 should have enough power to generate interesting sounds. The limitation however is on the memory. So any approach which relies on sampled data and big sound buffers will just Read more…
In the last couple of blogs I was setting the stage for my Radio Music Player for the ESP32. I was thinking first that I will use one of the many existing web based music applications together with my ESP32 Bluetooth Player. But I soon realised that either they want Read more…
