Freetronics Forum

I figured it would be too simplistic for the more advanced shields, but at the moment I am trying to simulate one of the channels on the relay shield, and potentially the logic level converter module in order to simulate the relay switching power to a 12V PIR sensor (http://www.jaycar.com.au/product...

Good Afternoon, I am new to electronics and have been using the Falstad Circuit Simulator (http://www.falstad.com/circuit/) to try and wrap my head around how different circuits work. I have been trying my best to port some of the various freetronics shields and modules into the simulator, and figur...

Yes, the problem was the FET. Another member of the meetup ended up having a couple spares

Good Afternoon! I just wanted to report back that my shield has been successfully repaired! Ross, a helpful participant at the Sydney Raspberry Pi meetup showed me how to troubleshoot the circuit board with a multimeter to isolate the problem, and then put on a soldering workshop to demonstrate gene...

Thanks for the clarification, do you happen to know of any places in Sydney where I would be able to pick up the part by Sunday? As I mentioned above, I was hoping to get my shield repaired on Sunday at the local hackerspace meetups soldering workshop as I am new and don't have the skills to do the ...

Good Morning, I have just made a trip to jaycar and picked up a couple of these: http://www.jaycar.com.au/productView.asp?ID=ZT2400 Which I am pretty sure is the wrong part, but was the only part they had in stock. If I do a search for 2N7002 on the element14.com website, there are several choices, ...

Good Afternoon, Thanks again for your meaningful response, I have been really impressed with the responsiveness from the freetronics team to all of my basic questions :) I have spent a small fortune on freetronics components so I'm sure there will be lots more to come as I continue to learn how all ...

I was afraid of that response! I had a sinking feeling as soon as I turned it on :( Have I done damage to anywhere else on my freetronics arduino or shield? As for the wiring, thanks very much for the nod in the right direction, from the datasheet, I thought that the pin closest to the coil was the ...

Good Evening, I have just purchased the 8 Channel Relay Driver Shield, along with a 12V DPDT Special PC Mount Relay (http://www.jaycar.com.au/productView.asp?ID=SY4052). The datasheet is available here: http://www.ficrelay.com.hk/details/FRM1.pdf I have wired it up according to the image: http://img...

Hello, I am new to electronics and using the chapter 6 alarm system project as my first project so please excuse me if my questions or assumptions are wildly incorrect. Will this project work with a single two wire PIR sensor (see the links below for the exact model)? Can I make this work with a 7V ...
