This project aims at designing and executing the advanced development in embedded systems for energy saving of street lights with light depending resistor. Nowadays, human has become too busy and he is unable to find time even to switch the lights wherever not necessary. This can be seen more effective in the case of street lights. The present system is like, the street lights will be switched on in the evening before the sun sets and they are switched off the next day morning after there is sufficient light on the roads. But the actual timings for these street lights to be switched on are when there is absolute darkness. With this, the power will be wasted up to some extent. This project gives the best solution for electrical power wastage. Also the manual operation of the lighting system is completely eliminated.
In our project we are using LDR, which varies according to the amount of light falling on its surface, this give an indication for us whether it is a day/night time. We have placed IR sensors in both sides of the road, which can be controlled by Micro controller (AT89C51).The IR’s will be activated only on the night time. If any obstacle crosses the IR, automatically particular light will be ON, for few seconds.
In our project we use regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the a.c out put of secondary of 230/12V step down transformer.
This fix covers fixing buttons on these cheap little remotes that come with a lot of electronic devices (in my case, an LED strip light).
The problem is that the carbon contacts either wear out or corrode (in my case it corroded… for reasons unknown). This means the pad no longer conducts when pressed so the signal does not trigger the remote to send anything to the device.
Diagnostic Tip: You can see if your buttons are sending anything by pointing your remote at a camera and looking through the viewfinder to see if the light is shown on the remote. Most cameras can pick up Infrared light, but our eyes cannot see it. This will eliminate the problem of buying a new battery to test if you don’t have a multimeter handy. If all other buttons work, but one or a few (in an area) do not work, you will see this in the viewfinder.
To fix, use commonly available foil tape (aluminum foil) which you can find at many hardware stores for about 6-12 dollars per roll. This can be pricey if you don’t have it laying around, but it’s generally cheaper than shipping your device for warranty service and/or junking the device which uses the remote (if required for function).
Adhere a small square of foil tape to cover the contact pad making sure that the aluminum side faces the circuit board. Ie. the adhesive should stick to the carbon contact, covering it. You are basically putting aluminum tape in place of the carbon. Anything that makes this connection and bridges the gap will work. This just happens to be cheap, convenient and easy to install.
Hope this helps someone else out there and saves you shipping and or the cost of your device.
