Hy
I got a Device that has a lot of those Mini Push Button Switch
I would like to control them by an Arduino. With a relais I would know how to do. But is there another way that is a bit smaller then 5-10 Relais on a Board.
Thx
Andy
What kind of device? How it is powered? Can you modify it?
If you want to simulate pressing the buttons, and it's a low voltage/low current device, you could use a transistor instead of a relay.
yes its very low voltage but how do I have to setup the transitor??
A transistor or FET will act as a switch. Perhaps a FET might be better, look at the 4066 analogue switch you get four of these switches in one chip.
hmm nice so it has to look like this (I know the voltage/ground isn't connected :))
Yes that's it. You need to connect the equipment ground to the arduino ground and the chip ground (pin 7). And Vdd (pin 14) to the arduino +5V. Then that should work
thx a lot just bought some of those and they work very good!
thx
