Need Help Draw This Schematic to Sprint layout
-

Its quite simple. That Help is meant just to draw it for you?Originally posted by paku View Post -
if any can help draw and share hereComment

hi paku, would you share the code too?
seems like a smal emf detector with bargraph Display, i would be interested to chekc my home with this tool
can help you with sprint layout 6 design
pls tell also the correct compent you want to assemble
for example i would take this
https://www.reichelt.de/?ARTICLE=229...SABEgI2p_D_BwE
instead of 10 single led and 10 single resistorComment

And antena parameters, please...Comment

atenna is a simple Piece of 5cm wire, it is just the same scheme as arduino emf detector
but it seems that paku wants a Version without arduino Environment
hope the code is a improoved Version, the Basic Setup is only for nearfield detecion
an aerlier idea of me was to get a higher Resolution by using a 1601 or 1602 Display as bargraph and using all columns and not only 10 ledsComment

Paku, the input of the power supply what should be - USB or somebody elseOriginally posted by paku View PostComment

Power goes to the 7805 which requires at least 2-3Volts higher than 5V and up to about 30V.Originally posted by Toros View Post
So USB power (4.4 to 5V) will not work.Comment

Aref, Vcc, Avcc from Atmega needs little Capacitors to Ground.
At Jp2 the Gnd Input is marked with + ???
The 7805 needs also Capacitors at In and Output.
The LEDs goes to Ground and over Resistor to Gnd.So there is no current control for the LED.
You have to connect the Resistornetwork like this:
PBx---LED---Resistor----Gnd or VCC. It depends what your Output Pegel is.
It is better to sink the current, it means the Resistors should go to Vcc and a logical 0 on the Outputport turns the LED on.
It schould be usefull to ad a ISP Connector to flash the ATmega.

THE CODE IF SOMEONE CAN ALSO MODIFY IS GOOD
