Cancelled Electronics class Monday 3rd Nov 2014

Sorry, but for numerous reasons I couldn’t make it yesterday.

However please proceed with reading the manual and trying out the things it says. The programmers are still not here yet (ordered from India) so we have to wait longer đŸ˜¦

Anyway, after making the power supply and testing it with an LED (with it’s resistor!)
Move onto the bit where you learn about transistor circuits and convinations of them. These things are really useful. After that begin to play with the 555 timer. There are loads of internet resources out there for using 555 timers. This is my favourite:

then see: http://www.instructables.com/id/Haunted-House-Bones-555-timer/step1/Spooky-Sounds-555-timer/

I will order some kits where you can learn to solder them together. The kit will be a power supply circuit.

Then we’ll use the AT89C2051 microcontroller.
