Day 1 Notes
Learning about the two versions of circuits you can make with the 55 timer, for two modes, Astable and Monostable.
The Astable mode the circuit has a constant output which's the duration can be varied by using resistors and capacitors with different strengths. In this example we used an LED as the output.
Then you've got to 'get inside the machine' The internal Logic of the 555 Timer.
Day 2 Notes
'Technology is an agent of power... and in practice is not the sum of the artefacts, but a system much more than the parts. this system includes organisation-mindset-symbols and a whole body of knowledge...' - Sonia Sheridan Bonds
The 555 TIMNER: MONOSTABLE MODE The Monostable mode includes a stitch, which when activated, lets the circuit run for a duration of time that is conditioned by the resistors and capacitors. (on once, HIGH)
H-Bridge for controlling the direction of a motor:
Using a relay:
