The triac should flip on and the light and it should be at nearly 100% brighness. However, this is not what`s happening. Itstead, the light doesn`t turn on at all. Can anyone explain why this might be If I change the gate to be always triggered (i. e. always voltage to the gate), the light turns on to 100% brightness as expected. Is it possible that the resistor sitting before the triac gate is too high (56 Ohms) I`m pretty new to this stuff,

so you`ll have to bear with me. Not sure what you mean by "net", but since IC1 has zero edge detection, does that mean I need to send the pulse to the IC1 (pin 1 & 2) before the zero cross actually happens Matt Mar 26 `12 at 20:26 @Kortuk After thinking about your comments a bit more, I think you`re asking how I got the zero cross. I left that part of the circuit out of the question to avoid confusion as it didn`t really have anything to do with it. I`m using another optocoupler to do that part and then feeding it`s output into the micro controller. Matt Mar 27 `12 at 2:44 @Kortuk The measurement was taken from a different part of the circuit (not shown in the schematic). I`m using another opto coupler as a zero cross detector to know when to push the signal high. Matt Mar 27 `12 at 16:01
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.....
