Using a microcontroller with a DAC and a LED array seems particularly well suited for this, while still being firmly a beginner level project.
- joshspankit 3y agoAs well, a cheap Dayton transducer may be a reliable entry point for producing the 40Hz
- mcapodici 3y agoDoes 50hz work? If so, just use an incandescent light bulb?
- bobdvb 3y agoShouldn't really need a DAC, just use the PWM output. Any $5 microcontroller should be able to do this with some reliability. Heck, the PiPico has programmable IO which could do this without the processor. Or hey, a 555 timer with the right resistors and capacitors would do the same thing.
