1  Using Arduino / Motors, Mechanics, and Power / Re: Need to move motor / actuator back and forth remotely via bluetooth on: July 25, 2011, 11:16:53 am
how do i do that? and can i somehow use a mosfet here?

thanks for the quick responses!

1:how can i measure the draw
2:should i get a slightly smaller relay?
3:the arduino could make the relay click before, now it cant... do these things fry easily?
4:thanks for all the help

I have it wired as such. should i use a tip102 because the relay has a 12v coil?

manually, the relay operates no issues @6 volts
its working @ 9v when i jump relay(pin16) to 9v+

should i use pnp or npn transistor?

i will upload photos soon

i have 9v+ going to arduino(raw) and 1 pin on relay
i have the 9v- attached to arduino(gnd) , 2 pins on relay, and 1 to the left pin on 2n2222(e i assume)
using digitalwrite (2,high) to send signal

signal is in this order arduino>>1k resistor>>2n2222 "B">> pin 16 on relay

any ideas?

I have a 1k resistor from the  arduino digital signal that then goes into center pin on 2n2222 transistor which is grounded on left pin, and right pin goes to #16 on relay. NOTHING!

im reading 3+volts before resistor
 1.6 volts after resistor
1.6 volts switched out of transistor

its not enough to flip relay

what should I do? my power supply is 9v (3X CR123 lithium camera cells)

I have a Firgelli LAC control board, and it needs the other type of actuator AND its too frggen big.

I have a DPDT relay from their site : http://www.firgelli.com/pdf/DPDT_Relay.pdf

my problem now is one everything is wired, it operates 100% as intended when i manually connect the switch to the relay.

when i hook the arduino up and turn digitalwrite(high) to signal, I can hear the relay ticking, but its not fully engaging enough to throw the switch.

what do i need to run from arduino digital out to relay so it can flip the relay?
im using 3.3v 2200ma lipo batteries (can string in row)


any advise?! smiley-roll-sweat smiley-mad

Also, if im sending serial signal through bluetooth, can i wire it straight to this serial motor controller

lemme know!!!

I purchased a 6 volt  WITH the limit switches.
It works fine on 3v, same speed for my load that it does @ 6v. I do have a 6v lithium cell, and a 3v lithium cell at my disposal.
Do i need a DC motor/driver board?

I really am trying to keep this "device" on a diet, so size is everything! This pq-12 is awesome btw smiley

HEY GUYS,
I'm trying to power a PQ-12 Linear Actuator by Firgelli by bluetooth serial trigger@!

I got the Arduino mini pro to activate to PQ-12 by modifying the "BLINK" script to a different pin. thats all.
I also put baud setting, one second serial counting feedback (1+1..2....2+1....3....etc) SO I KNOW THE SERIAL FEED IS 100%. When i attach both units, (pq-12 and the bluetooth mate gold), the bluetooth   connects, but when i send my remote trigger comand that resets the counter, it does not trigger the PQ-12 like it did VIA usb and NO bluetooth mate gold.

i hooked up a small 6v camera batter, a 3.3 v lipo camera better cr123a or something...?
neither changed output (does this rule out having enough power?
if you look up the WWW.FIRGELLI.COM and look at schematics, how can i flip the voltage ? I wanna retract and extent the linear actuator .... hope ive been descriptive enough
