Turns on and off a light emitting diode (LED) connected to a digital pin, without using the delay() function. This means that other code can run at the same time without being interrupted by the LED code. The circuit: - Use the onboard LED. - Note: Most Arduinos have an on-board ...
inputs += c; //means inputs = inputs + c } if (inputs.length() >0){ Serial.println(inputs); if(inputs == "A"){ digitalWrite(relay1, LOW); } else if(inputs == "a"){ digitalWrite(relay1, HIGH); } else if(inputs == "B"){ digitalWrite(relay2, LOW); } else ...
"FC 01" means the value of the Function Code is 0x01.There are more Function Code. In order to avoid overloading newbies, this tutorial only present some essential Function Code.When using Arduino Modbus library, you need to:Decide which Function Code to use Give addresses for each Arduino...
A new chip means a new Feather, and the Raspberry Pi RP2040 is no exception. When we saw this chip we thought "this chip is going to be awesome when we give it the Feather Treatment" and so we did! This Feather features the RP2040, and all niceties you know and love about Feather...
