For one of my current projects I had a closer look into the HTTP Protocol. Usually you might use a separate library for doing http calls from Arduino (e.g. with an ESP32) but if you are low on memory, you might get away without this by just using the WiFiClient: Read more…
I had the need to pass some callback functions to some of my generic C++ Arduino classes. So I was asking myself if we can use Lambdas in Arduino. Here is a small test sketch, to verify this. #include “TestLambda.h” void setup() { auto f1 = [](int number) { Serial.println(number); 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…
