It’s a constant of composing for Hackaday, that whenever a job appears utilizing a 555 timer, somebody will state “You might have utilized a microcontroller to do that!”. It’s something that [Shranav Palakurthi] has approached with the ATTiny555, a job that emulates an entire 555 by making creative utilize of the humble as well as ubiquitous microcontroller chip. We’ve all been guilty of it at some time, however now at last the ATTiny85 enthusiasts have conclusive proof that their favourite piece of affordable silicon can verify its mettle.
The full details of the ingenious 555 replacement can be discovered in its GitHub repository, as well as for those ready to take the plunge it’s as basic as adding a resistor as well as updating the firmware. It’s not the best 555 replacement with its imperfect analogue performance as well as swapped reset as well as ground pins, however it does nevertheless bring the advantage of a lower supply voltage.
You can see the gadget in action in the YouTube video below the break, however on the other hand rejoice that lastly there’s a method to replace all those unnecessary 555s with your favourite low-cost 8-pin chip!
While we’re on the subject of the 555, don’t fail to remember we’re running our 555 contest again.
