Step 3Components and PIC programming
The components are all readily available , and should not be a problem to obtain.
Should you wish to order the PIC from me, then please request by Email and I will reply with the cost of shipping a pre-programmed PIC.
For you to self programme your own PIC 16F684 the HEX file is here available.
Carefully insert and mount all the components (following the component layout here), start with the low level components such as resistors first. Solder and trim the component legs.
Take care that the components are correctly orientated or components will be damaged. Note the LEDS have a flat side (the cathode!). The PIC should be ideally be mounted in a Dil socket and be sure that it is correctly mounted with the notch at the correct end as the layout picture. Note the polarity markings on the bridge rectifier and the Electrolytic capacitor! double check your component assembly and also the printed circuit board (for bridges/shorts or open circuits or properly soldered joints), before applying power. The circuit and PIC have been proved and tested, so of it fails to work as expected the fault is with the construction or a failed component, the most likely being that a fault exists on the copper side of the PCB, DOUBLE CHECK EVERYTHING (A visual check is the most important check you can make before any other!).
