I need to create a project where i take my arduino mega and read a temperature from a probe.
then based on the temperature turn on a lamp to adjust to a set temperature.
IE keeping the temperature set to a say 85 degrees.
Im totally new to this.
the probe could do with being water proof and maybe have a display and either buttons on it to adjust the temp.
Ive seen the relay shields that have 4 relays on them and this could be useful to use as i may want to replicate the process on 4 differnt ones at 4 different temps.
Im in the UK so must be able to use 240v and im likely to be using a standard 100w light bulb in the lamp.
Please can anyone point me in the right way or guide me to look at the right place.
Awol, I've always assumed that the light bulb regulations in the UK would be avoidable, in that there are some environments (e.g. machine shop) where incandescents are desirable or necessary. Some legacy equipment such as incubators would need them too. I was expecting that you'd still be able to get them but they would command a price premium that'll likely rise over time. I have no hard data - is the change really so draconian?
why not, AWOL? at least in europe you can still find them...
anyway, it doesnt not sound like you need a mega, you'll probably be fine with a uno or duemillenove ...
places to start searching for parts might be sparkfun.com or robotshop.ca (not saying you should necesarily buy them there, but look at what they have in stock, to get an impression of what is available...)
yeah, I know... (granted I am in canada at the moment) but, I have not noticed any effect - at least 6 months ago in the netherlands getting regular bulbs was no problem... ...the day when we run out will make me sad
