Thanks. However, I also read that the DS1307 has an alarm function. Would it be possible for that alarm function to trigger a thyristor to start the LED flashing? The thyristor could maybe be reset...

I drew more PCB and I would order them together to save on transport costs: is it possible?

I can't see anything about an alarm function in the DS1307 datasheet. The square wave output outputs a square wave (!) at a minimum frequency of 1 Hz, so that doesn't help you much - you will need a...

The PICAXE 08M2 is relatively expensive considering it needs a bunch of other parts to function. I can get an ESP8266 microcontroller for £1.40 and use it without an RTC or, alternatively, I can get a...

I would suggest an Arduino pro mini from ebay (around $2) you still need a wall wart to power it and (more importantly) a serial interface cable to program it if you don't have one or can't cobble one...

It may be easiest to just post the part number of the chip it uses. That would give us the data sheet to tell you what the pins do. Typically these boards from china don't have any documentation, I...

How are Fritzing core parts identified? For example, I'm having trouble identifying a parts number, brand or any more details around 'Rotary Potentiometer (Small)': Part: Rotary Potentiometer (Small)...

I expect that would be because it is a generic pot, aimed at representing the class "pot with shaft" rather than any specific make or model. In fact if you drag it to the breadboard and click on it in...

Hello guys I m a new user and I have created a project in fritzing. I have an arduino and some moto drivers and some other elements. However I want ONLY some of them to be included in PCB layout and...

The PICAXE 08M2 doesn't need any other parts to function once you have programmed it, and all you really need to program it is an RS232 port and two resistors - the Rev-Ed kit is just the most...

Thanks for everyone's responses. I found that I can get a mini or nano (?) Arduino for £1 which seems like the best solution since it's got everything it needs and is so very cheap.

You can have more than one PCB in the PCB View - just drag another 'Rectangular PCB - Resizable' from Core Parts on to the PCB view. Then you can put each of your components on whichever of the PCBs...

They appear to be implying that the screens want +12V to power them (I would have expected 5v, but if they are for a car then 12V does make sense) as long as you verify that is correct, because...
