Now the PCB kind of looks the same as the previous one but it has some changes. I’ve ordered it in purple form PCBWAY. This time it has two sensors and I’ve made it so you could just snap the sensor PCB with your hand without having to cut it. So if you want to try this awesome project, get my GERBER files from below and then go to PCBWay.com. Here it is very easy to order for just 5 dollars. Click the quote now button. On the next page add the size of the PCB, the amount and select a color. This time I’ve selected the purple one. Add to cart and on the next page upload my GERBER files and place the order. That’s how easy is to use the services of PCBWay for PCB prototyping. As always I receive the PCBs in a few days and they look awesome. I think that for this project I like better the purple color than the red one from the previous version.
