555 timer clock
Created on: 31-12-2018 By Gee
The very first part of Ben eater's 8 bit computer is the computer clock. This is made by using a 555 timer, some resisters, capacitors and an LED to show it working.
Each time the LED is on, it represents a clock cycle. This will eventually control the computer cycles in a similar way to how an oscillator works on other computers.
I had another look at the video on YouTube that Ben made and followed it the best I could with the parts that I had.
I used a 220ohm resister instead of a 1kohm and tried various different capacitors for the clock speed.
At first the LED just stayed on and I wasn't sure why. I'm still not sure what caused it, but I fixed it by wiggling a few of the components and wires around.
I'm glad to say that the first part of my Ben eater computer is working. I'll need to find time to make some more of it soon.
I have another project that will require buttons, so I'll order some extra for the manual clock pulses and the pause for this computer.
