Hi people,<br>
<br>
Additional ideas for the technical workshops.<br>
<br>
I was thinking that - if it has not already been covered, a potential<br>
future workshop could build on the PIC workshops that have been done.<br>
<br>
The idea is basically to learn the basic input/output blocks.<br>
<br>
examples,<br>
<br>
many new people to microcontrollers, connect a switch between +5v to the<br>
pic input pin, then get frustrated that the switch is unreliable due to<br>
floating when the switch is open. The block would be a switch, with the<br>
the pull-up or down as required. Explanation of why the pull-up/down<br>
resistor is required.<br>
<br>
a simple relay output from the pic, using an easily obtainable mostfet to<br>
drive the relay, and include the protection diode. Again explain how it<br>
works, and why we need the mosfet, and what the purpose of the protection<br>
diode is.<br>
<br>
a simple piezo buzzer, including any protection resistors.<br>
<br>
a simple potential divider, explain how to calulate the drop between the<br>
input and output.<br>
<br>
how to correctly connect an led, and calculate the current limiting<br>
resistor.<br>
<br>
It would be my hope that these building blocks were universal, and could be<br>
applied to any other controller type such as AVR, arduino etc. as well as<br>
non uP controlled projects. For example using the switch module connected<br>
directly to the relay module would still produce a nicer circuit than<br>
running the coil voltage through the switch directly.<br>
<br>
The basic idea is to build a small library of very simple circuits that can<br>
be combined with the existing pic workshops so that people can go away and<br>
build circuits of their own, that will hopefully be reliable, and can be<br>
combined into larger projects by just duplicating these small blocks.<br>
<br>
This is probably a horrible description, but I hope that people understand<br>
what I mean.<br>
<br>
Additionally, would there be any interest in TTL LOGIC as a workshop?<br>
<br>
Graham<br>

That sounds like a great idea. I for one could do with some more basic<br>
electronics knowledge.<br>
<br>
What else did we come up with at the social?<br>
I suggested an introduction to the operating principles of transistors, by<br>
building a very basic headphone amplifier. What was the other idea?<br>

I think other ideas that were mentioned were:<br>
<br>
Output control, eg. making things happen in the real world, for example<br>
motor control or servo control.<br>
<br>
Communicating with a microcontroller from a PC. I think this is the<br>
technical workshop for a week monday.<br>
<br>
I have 2xPickit 3's that I can bring (Mabey a 3rd and a Pickit 2) So if<br>
anyone needs to use one, they are more than welcome.<br>

Thanks for all these ideas guys.<br>
<br>
My first tutorial covered connecting LEDs and switches, and demonstrated<br>
the importance of debouncing switch inputs. but didnt otherwise go into<br>
the reasons why.<br>
<br>
I can see the argument that we should include at least some simple<br>
explanations of the why, although i am unsure the best way to deliver<br>
that. I felt that the worksheet approach worked well, with everyone<br>
working at their own pace leaving me free to give specific help where<br>
required. So i suppose i should try to work some explanations into the<br>
worksheet where possible.<br>
<br>
I also plan to put the resulting worksheets and support materials online<br>
for future, and other peoples, reference.<br>

Yes, thats my plan.<br>
<br>

That would be very helpful, last time we all had to share the one<br>
pickit2 i brought.<br>
<br>
<br>
<br>
I am trying to put together a list of components for the starter kit to<br>
base these tutorials on. It doesnt have to contain everything we might<br>
cover, like servos etc, as we can always do booster packs later. I was<br>
hoping to keep the cost under a tenner each, but have enough components<br>
to cover plenty of tutorial options, and allow some tinkering.<br>
<br>
So far i have come up with this list, can people please give their<br>
suggestions:<br>
<br>
PIC16F1455<br>
MB102 Breadboard<br>
Jumper wire kit<br>
Long pinned header for programmer connection<br>
USB Uart board and cable (possibly CP1202 based)<br>
LEDs a handful of different colours + limiting resistors<br>
Small push button switches<br>
Piezo Buzzer<br>
LDR and/or Thermistor<br>
<br>
I also need to get an idea of how many people would like to buy these<br>
kits so i can bulk order the components to save us money.<br>
<br>
<br>
<br>

<br>
There is a nice little power supply module for the MB102 breadboard:<br>
<a href="http://www.thelittlebritishrobotcompany.co.uk/index.php?route=product/product&product_id=79" target="_blank">http://www.thelittlebritishrobotcompany.co.uk/index.php?route=product/product&product_id=79</a><br>
<br>
It allows you to power the breadboard rails from a 6.5-12V power plug or USB at either 5V or 3.3V. I'm sure you can get them even cheaper than what I've listed above.<br>
<br>
I was wondering if it's at all possible to make the tutorials more microcontroller-agnostic? I prefer using Arduino, and others have their own favourite micro and development platform.<br>
<br>
Cheers,<br>
Gerrit<br>
