The laser harp is an electronic instrument that is played by blocking laser beams. Several laser beams are produced, and a note is played when one of the beams is blocked by the player, similar to plucking a stick on a real harp.
Power the servos separately.You don't need to add the servo voltages. All of them should share a common ground with the Arduino. You do need to add the current. Each servo will draw two or three amps so you need six to nine amps available at the supply.
Theottle progress!Left lever is moving.Right now with my gearing and 9v battery it takes about 6sec from idle to full power. Hope to get extra speed with the 12v power supply.My main problem now is the wires. I need one with a steel ball that locks ...

Tech & Coding for Newbies!Host: Brett Bauma "Makers On Acres"on American Preppers Radio! Saturday 9:00pm/Est 8:00pm/Ct 7:00pm/Mt 6:00pm/PtLive Listen and Chat go to: http://prepperbroadcasting.com/listen-chat/Many of the people who are involved in prepping and or homesteading may stay clear of a lot of technology. Many people steer clear of technology, knowledge and learning, because they fear they may not be able to learn it or start the new skill at an older
I think that's basically what the SevSeg library does CrossRoads. As a matter of interest though, the default config for that library is to have the resistor on the common only, ie one per digit not one per segment.
Create an arcade console and play Pong wirelessly on your computer screen. You will use 2 slide dimmers as inputs and an Arduino Bit to interface with your computer.*To make this project, you will need to download the Arduino software. You will also need to download Processing to run the Processing sketch.This sketch will allow you to send two analog sensor values from the Arduino module to a Processing sketch that is running a version of the game Pong. The Pong paddle positions move based on the sensor values in this two player game.For more “getting started” Arduino sketches, click here.For support check out the littleBits and Arduino forums.To learn more about coding, find examples on Arduino’s website.This project is a REMIX of the Analog Pong project by littleBits.
