In this project I use a transmissive photo interrupter to detect movement, count the movements and show the count result on a 7-segment display. Continue reading Photo interrupter with Arduino
This project is part of my Arduino Pinball adventure where I’m learning Arduino programming while having fun building parts for a pinball game. The pinball targets in this projects is what you would call “drop targets” in traditional pinball games. The ball knocks out targets one by one to get score and eventually a bonus when all targets are down. Continue reading Arduino Pinball – targets
I found a all-in-one printer in a container and I figured it would be interesting to take it apart to see the inner workings and maybe find some interesting electronic parts I could use for other projects. And wow there was a lot inside! Continue reading Disassembly for parts: Sharp AR-M201 All-in-one printer/scanner/copier
I wanted to understand how to change the color on a RGB LED and how to control it. This setup have a default blue pulse and a push button to change the color to red-orange for a short time. Continue reading RGB LED control with a button
I’m testing out a flow meter and have made Arduino code where I can push a button to run a 12V pump until a set amount is measured by the flow meter. Continue reading Flow meter calibration
I have had an idea for a simple automated bottle filler for some time now. Filling bottles when making your own beer can be a tediuos task. This is the first renderings of the “BottleBot” work in progress. Continue reading Bottle Filler “BottleBot” Concept Renderings
Lots of cheap solenoids can be found online, but can they be used in an Arduino Pinball game? This post is part of my Arduino Pinball Project, and I test out cheap solenoids and print out some basic flippers to try out the designs.
