These are two pictures of my circuit on a breadboard. The one on the left shows it hooked up to a oscilloscope and a power supply. You can see the LED's on a smaller bread board hooked together by alligator clips. The one on the right shows the actual main part of the circuit. You can see the Arduino the 555 timer and the potentiometer.
Oscilloscope Pictures
These are Pictures of an oscilloscope measuring the waveform of the output of my circuit. You can see it running at 60 Hz on the left 48 Hz below and 80 Hz on the rightside. These are different frequencies at which I can flash my LED
Building the Circuit Board
Here you can see the circuit and PCB board I made for my project. On the left is the circuit board. This is basically a map out of what my circuit looks like. You can see in the middle is the 555 timer and above it is the Arduino Nano. Next to the Arduino you can see where the OLED display will come out of. To the left of the 555 timer, you can see the mosfet IRLZ44Z which then goes into a screw terminal which will connect to the LED board. To the right is my PCB circuit board which is a layout of the printed and finished circuit. There's everything from the circuit board on the left. There's a couple of screw holes and a few jumper cables which will carry ground from a couple different points.
