Step 3Construction
start with the small parts first as it will make it easier. write top at the top of the board so you dont forget which way up it goes. put the dil socket in first as this will orientate you in you quest to insert components. make sure the notch on the dil socket faces top.
then you can start to put in all the components, remember small first. resistors can go any way around. LEDs cant long leg is the positive (+) and short is -. diode have to go aroung the correct way. the stripe is the cathode (negative) use the pictures below to find out where they go (remember if it is too small you can click the i symbol and it will show you the full size of the image). try and use a different colour for the signal recieve LED.
make sure the big capacitor (the round one) has the long lead on the + side. or the grey stripe on the other side.
now you can build the boards, make sure you look at the pictures below
