This wireless remote control switch production is relatively simple. All components parameters we are testing is complete. Reader component parameters we provide installation can be completed in the production of the first resistive and capacitive components such as welding and welding on the IC socket Finally welding on the wireless receiver modu

le SH9902. 78L05 first welding. Conditional netizens available external 5V DC power wireless receiving part debug plug IC1. Negative pole to the ground in the circuit. +5 V connected in 78L05 output of multimeter DC voltage range measuring IC1 14 feet voltage when pressing the remote control every time. 14 pin voltage should sometimes significantly change. Otherwise, the wireless receiver module is not working properly. receiver module with or without inserted upside as normal retest IC1 17 feet of the ground voltage hold the remote control. feet voltage output is high or check IC1 whether the inserted upside Another point to be noted is that some production in soldering integrated circuit socket welding unskilled. address of 1-8 feet and the ground or high level collide. inadvertently decoder chip encoding. caused by the transmitter and receiver end address password is not uniform and can not be decoded on how to address coding. below The article introduced; last measured 11. 12 feet voltage output high when the remote control button click the corresponding two feet. Mains supply part of the debugging: This part of the debugging circuit can be determined by measuring the value of the voltage as long as the voltage across the measurement CW1 If the measured voltage is 11 13V between the section and the rectifier of the capacitor buck part of the circuit is working. So users can quickly master this remote switch debugging...
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.....
