Hello everyone! I have been trying to use the Arduino Uno to create square pulses at the following frequencies, 10Hz, 5Hz, 1Hz, .5Hz, and .12Hz using PWM. I’ve been using Timer1 in CTC mode with a 1024 (1562Hz) prescaler. The problem is that as I lower the frequency, the waveforms I see on the osc…
