Simple circuit diagram is a schematic remote control, remote control where it consists of two parts of the transmitter and receiver. The first part is a transmitter, circuit diagrams for transmitter IC is controlled by the NE555. This system works by detecting the signal emitted frequency. Frequency signal so that the transmitter circuit (NE 555,

can also use the LM 567 as a generator frequency) must be equal to the frequency decoder. The following is a schematic remote control drawing transmitter: To facilitate the process of tunning, the R1 is a resistor in the receiver variable. While the transmitter is a fixed value. When the circuit is ready, so the system works well, the first step taken is to tunning, by way of the transmitter is turned on continuously, while the receiver R1 to set the value to be able to detect the signal transmitter (can be determined by the reaction of the relay is clicked). For the second part is a circuit diagram of the receiver, the receiver is controlled by the LM567. The following is a schematic remote control drawing receiver: In the picture on top of each channel is designed with a different frequency. By considering the bandwidth of the frequency detection signal LM 567, inter-frequency channels should have a big enough difference, let`s try remote control with a difference of 5 KHz.
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.....
