Simple Arduino project to blink an LED on and off at regular intervals using digitalWrite and delay functions. Ideal for learning basic hardware programming. - omar ...

This isn’t an ESP8266 shield, either: you can write code for the ESP module, connect the serial pins, and hit the program button. The basic functions of the Arduino IDE – pinMode, digitalRead ...

If you are only concerned about using Arduino IDE functions, all you need to worry about are the Arduino pin numbers. But if you want to program using the corresponding microcontroller’s pin numbers, ...

digitalWrite(msPin[1]=LOW);} Note that there are 13 instances of the digitalWrite function with incorrect number of operands. Any fewer than 13 and the compiler correctly spits out errors. 13 or more ...

One downside of the current version is that the compiler must be able to resolve the pin number for the digital IO functions at compile-time, and avr-gcc is not always able to recognize the pin is a ...
