how to build a circuit to measure rms value of the sine wave signal with frequencies vaying from 1 Hz to 1 KHz.
the voltages is of range +/-20 mv(if it is unamplified), +/- 10 V if it is amplified.
Thanks in advance.
Hi ,
I want to make an amplifier to amplify the load cell output of 2mV/V(Excitation voltage) to Voltage of range 0 to 10 V
The key point is my load will vary from 1 Hz to 1 KHz. so how to amplify this a.c signal without noise.
My loadcell bridge resistance is 350 ohm.
I ve one amplifier...
Hi everyone,
I want to design a data acquisition system with data logging with graphs of the sensor's output.
I want to design it with an ATMega8(L) microcontroller.
I already have an Atmega 8 microcontroller development board that came with a line follower kit. In that board i can program the...
Yesterday i bought a joystick switch.
It has 3 legs on the x axis and 3 legs on the y axis side.
The switch also has a centre push button which has 4 legs.
I want to control two motors for my moving bot
i.e) forward, reverse, left, right.
How can i connect those pins.?
Is there any schematic?
I...
Hi,
I want to control upto 8 dc toy motors wirelessly(clockwise and anticlockwise rotation).
I want to make my own transmitter and receiver circuits.
Can any one please help me for making this wireless remote control.
And you would be helpful if you provide me a working schematic diagram.
I m having an ordinary dc motor without gear(i got it from a toy car). I gave a 9v supply to the motor it works fine. Can i give a 12 v supply to it for more speed?
How to calculate the maximum voltage the motor can withstand and work fine?
