Stefan Wagner published another great project on Github. He writes: Sometimes AVRs are operated without an external clock. The internal oscillator does a good job in most applications, but when it comes to precise timing, it is too inaccurate. The accuracy of the oscillator of an AVR is only +/-10%. Fortunately, the oscillator can be […]
