I have a question about the connection of coin slot to relay..
I
Is it better to connect the coin slot directly to microcontroller or should I connect it to relay before to microcontroller.

Coin slot:
red=Vcc
black=Gnd
white=counter
gray=coin

with these four wires, where should i connect the relay?,
once i inserted a coin (1 peso), i measure the output voltage, and it reads only 0.2V which cannot drive the relay..what should i do?.

any help is much appreciated..thank you in advance.! ....etc

circuit diagram of coin insertion mobile charger

This is the smart coin based mobile charging system that charges your mobile for particular amount of time on inserting a coin. The system is to be used by shop owners, public places like railway stations to provide mobile charging facility. So the system consists of a coin recognition module that recognizes valid coins and then signals the microcontroller for further action. If a valid coin is found it signals the microcontroller and microcontroller then starts the mobile charging mechanism pro ....etc

Usually ordinary solar panel is always faces
only in one direction. Because of this reason the solar
panel may not get sufficient sun rays to work. In this
work SOLAR PANEL CONTROLLER AND POWER
OPTIMIZATION is done in order to overcome this
defect. Here the panel will rotate according to the
readings read by the LDR. So it will utilize the full sun
light to work & power optimization is also done by using
the LDR.
This work mainly designed to control the solar
panel automatically, maintains face of the solar panel
towards the sun. Thi ....etc

how to make piezoelectric mobile phone charger circuit

Development of The Project:
The power generating soles are one of my first concept projects. I started my first prototype last five years ago although it was a very primitive, compared to my current design. My old prototype had two TO-3 plastic spacer sandwiched between two piezo discs. It produces a fair amount of current, enough to charge a Nokia 3310.

5 years later, I came back with the idea of using the sandwiched piezo setup, this time integrated to a charge collector and powerbank. ....etc
