I calculated the RSet resistor value at ~17k though it should probably have been 28k according to the table on the page (the MV7744 data sheet list Vf = 2. 1V and If = 20mA) but that`s for an LED matrix not individual LEDs happy for you to work out what this should be . Used Keith Neufeld`s Arduino Quadrature Encoder Library available

here to download and though initially it didn`t compile reading further in the post I came across instructions to add: Also intending to use quistoph`s DebounceButton Arduino library (link currently not working) to provide onPress(), onRelease, onHold(), onClick() functionality which combined with the push button of the encoder could be useful as a hidden` control system should we need it My colleague Nick discovered the requirements for a common ground for the I2C bus so we`ll need to plan this into the circuitry of one of the boxes probably the rotary sequencer The problem is first that they have a lot of contact bounce and trying to suppress this in software and determine the direction of rotation at the same time is a bit of a big ask and normally it won`t work. I don`t know if you noticed but some times the Project sketch would go in the wrong direction at times.
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
