So far in my bots Ive been reusing the same 2 transistors that I got with my original ARDX kit.
According to http://oomlout.co.uk/starter-kit-for-arduino-ardx-p-183.html
Im using these:-
A “NPN bipolar junction transistor used for general purpose low-power amplifying or switching applications”.
I’m using them as switches for my motors BUT I think the power is too high for these transistors.
(At the moment I’m powering my bot with 4xAAs) and the motors often stay stuck on instead of switching on & off.
But I’ve just bought these Battery Packs to lower the power a little:-
But I need to go back for these snap-on battery connectors:-
and Im wondering which of these would be suitable for my use?
“@GeekMoore: @ManchesterBudo @patlink72 you’ve had 5min.” ha! 🙂
Ive no hbridge so I tried running both motors off the Arduino but I think it needs more power coz they both won’t run at once SO im on way to asda for batteries.
I had to solder the cables onto the motors (and you know how terrible I am at soldering- then I wrapped tape round for extra security)
The wires kept getting pulled out accidentally otherwise that was doing my nutt in.
