Sidd S asked vibration motor with tws434 and rws434?
Hey guys, I am trying to make a vibration motor run using wireless communications between a tws434 and a rws434. I am also using a 4 bit decoder and encoder (HT12D and HT12E). At the bottom of this question are two links, one for the vibration motor page and one for the schematics that i correctly connected. The schematics include the tws434 connected with the ht12e and the rws434 connected with the ht12d. I have the VE connected to ground permanently on the ht12e, and i am only using d0, not d1-2, and i am manually connected it to ground instead of using a button. on the receiver, i do not have vt connected to anything, and i am only using d0 on that too, and having that connected as teh "direct LED example", but using the vibration motor instead of the LED. Also, i have used 4 1.5V batteries for each of the transmitter and receiver circuits. Regardless of everything being correctly connected, the vibration motor refuses to run. Ihave even made sure that it works correctly by connecting it to power and ground correctly.I am not too experienced with circuitry, and I could use a little bit of expert advice, and i would appreciate any help =D Thanks so much! and ofcoures 10 points to the best answer here is a link to the vibration motor page: http://www.sparkfun.com/products/8449 the data sheet for that is in a link labled "datasheet" in the middle of the page here is a link to the schematics i have used: http://oap.sourceforge.net/datasheets/rf.pdf make note that i have used the 4-bit encoder and decoders, and not the 8bit ones. i will be here the whole time today so you can email me at email@example.com if you have any questions. thanks a lot =) i apologize for the "direct led example"...the datasheet i provided is a bit different than the one i have in hand,but the way the direct led example works is that D0 or something similar is connected to a 680 ohm resister, which is connected to the led (or motor in this case) and the other pin of the motor is connected to ground
And got the following answer:
It's not clear what you mean by the "direct LED example" - the only one I see drives the LED through a transistor. In any case, it's not surprising that the motor won't run because it needs 75-85 mA, which you'll never get from an output of that decoder IC. Using a transistor as a current amplifier is a good idea, but not with that 470 ohm resistor as shown in the "sample valid transmit circuit". Replace the resistor with a direct connection to ground and put the motor where the LED is shown. To prevent damaging the transistor by the inductive kickback of the motor, place a small diode, such as a 1N4148 ( http://www.sparkfun.com/products/8588 ) across the motor leads, with the anode end facing the transistor (the stripe indicates the cathode, facing away from the transistor). EDIT********************************************************* My advice is the same as before. The motor needs 75-85 mA, but you cannot get that much current directly from the decoder IC. You must boost it up using a transistor as shown. Use the relay driver circuit, with the motor instead of the relay coil. Don't forget the diode.
The sparkfun relay perform incredibly properly with various applications that are precise to power distribution and protection. The relays include wide adjustment ranges using a scale that’s simple to read either in three or 4 digits according to the model. These sparkfun relay help in increasing the flexibility on the applications, decrease the general power and maintenance fees.
