Using Geany as multi-language code editor (IDE) for your Arduino project
When working on an Arduino project, you often need to create more than just one file. This could be combination of C and Python. You have the choice of switching between Python IDE like IDLE or PyCharm and a typical C CLI-based editor vim, and Arduino Genuino IDE to edit…
AVR-GCC programming – Simple Interrupt for blinking LED on Arduino Uno using pure C
Interrupt is powerfull tool because you can harnest the hardware power of Arduino, for instance to blink multiple LEDs simultaneously. Supposed you want to blink a LED using interrupt and not a timer, the following example will toggle PIN13 (PB5) which is liknked to the in-built LED using Timer. …
