Hey guys,
my group and I are currently working on a project, and we have to come up with an astable 555 circuit with variable duty cycle(10%-50%) to power a laser diode.
From the attached waveform, the pulsing suddenly stops after about 17 seconds, and it is rather noisy. Also, we need to bump the voltage up to 1.9V to 2.2V.
Would appreciate any help to correct these problems.
