Blazing Paddles. Introduction I purchased some XY joysticks from China last year and they have been in a storage box ever since they arrived.
I decided to do something with one and thought about a "Pong" game for my Arduino and one of the inexpensive TFT SPI 2.2 inch LCD displays that I have used in other Hackster projects. But I was not really happy with the free code, so I took the Open Source Playground example on the Arduino site and really embellished it for action. Points are awarded at the start of the game, 9 points for the Arduino and 9 points for the Player. The Arduino's goal is to get the ball from the top to the bottom and conversely, from the bottom to the top. The Player's goal is to stop the Arduino from scoring by blocking the ball. Hello World 0.96 inch 128X64 I2C OLED, on Arduino Uno, using u8glib library. It's a 0.96" 128X64 OLED, I2C (or IIC) interface, with SSD1306 driver, 3.3/5V compatible.
There are 4 pin on the OLED module, GND, VCC, SCL and SDA. Connect to Arduino as: GND - GND on Arduino Uno VCC - 5V on Arduino Uno SCL - A5 on Arduino Uno SDA - A4 on Arduino Uno u8glib (Universal Graphics Library for 8 Bit Embedded Systems) is a graphics library with support for many different displays. This video show how to download u8glib, import the library from the "Add Library" Menu in Arduino IDE, and run the HelloWorld example in the library. In the HelloWorld, only un-comment the following constructor to make it work:U8GLIB_SSD1306_128X64 u8g(U8G_I2C_OPT_NONE|U8G_I2C_OPT_DEV_0); Vinduino water pressure meter - Van der Lee Vineyard. Measuring water pressure in agricultural irrigation systems is standard practice.
One application is checking for pressure drop when irrigation valves are opened, and thus give feedback that valves work correctly.Pressure difference can also be used to measure the amount of water flowing, and help tune for even distribution of irrigation water.Here's how to make a digital water pressure meter, based on the Arduino Pro Mini micro controller board, and the Vinduino PCB.The used pressure sensor is a $20 device, available on-line ( It has a stainless steel housing and comes complete with a watertight connection cable. There are several ranges available. We purchased the 200 PSI version, the same range as the analog meters installed in our vineyard.
This sensor gives an output voltage between 0.5V and 4.5V that scales linearly with the measured pressure, 50 psi per volt.Hooking the sensor up to the Arduino board is easy. 2X Yellow Blue 0 96" I2C IIC Serial 128x64 OLED LCD Display Module for Arduino.

Accessing pixels along a circle. Hi!
Got an annoying problem. I have: A binary image containing the result of a canny edge detection. A Vector containing all points on a circle. I want: To draw a little dot on all points where the circle intersects a white line on the canny image. The problem: I can use the points with draw functions such as circle(). The code: Any help is appreciated. //John. ME170C/ECE181C Course Webpage.

After years of painstaking research and designing / building numerous drink bots, we learned that the best way to dispense alcohol is through a peristaltic pump. Why? For many reasons. The liquid doesn’t flow through moving parts, it bypasses the necessity for expensive flow meters (which usually also have moving parts) and it meters the correct amounts independent of viscosity and density. These dispensers have their smarts built in.

How to build an arduino energy monitor. Including voltage measurement via AC-AC voltage adapter and current measurement via a CT sensor. This guide details how to build a simple electricity energy monitor on that can be used to measure how much electrical energy you use in your home.
It measures voltage with an AC to AC power adapter and current with a clip on CT sensor, making the setup quite safe as no high voltage work is needed. The energy monitor can calculate real power, apparent power, power factor, rms voltage, rms current. All the calculations are done in the digital domain on an Arduino.
Step One – Gather Components. Introduction. Tweet-a-Watt! A safe and simple wireless power monitor. This project documents my adventures in learning how to wire up my home for wireless power monitoring. I live in a rented apartment so I don't have hacking-access to a meter or breaker panel. Since I'm still very interested in measuring my power usage on a long term basis, I built wireless outlet reporters. Building your own power monitor isn't too tough and can save money but I'm not a fan of sticking my fingers into 120V power.

The Chemical eTape Liquid Level Sensor is a solid-state sensor with a resistive output that varies with the level of the fluid. It does away with clunky mechanical floats, and easily interfaces with electronic control systems. What separates this from our other eTape Liquid Sensor is the Teflon (FEP) jacket that is rated for use in chemical, petroleum, and food safe applicationsThe eTape sensor's envelope is compressed by the hydrostatic pressure of the fluid in which it is immersed.
This results in a change in resistance that corresponds to the distance from the top of the sensor to the surface of the fluid. The sensor's resistive output is inversely proportional to the height of the liquid: the lower the liquid level, the higher the output resistance; the higher the liquid level, the lower the output resistance.This is a very unique sensor, we haven't seen anything else that is affordable and accurate for measuring liquid level.
