    Alternative to acceleration estimation with encoder velocity data

    I tried to estimate angular acceleration of a shaft with angular velocity points collected from an incremental encoder but, when I differenciate numerically, errors of estimation became very high due to the delay in capturing flanks (detecting slits). What alternatives do you suggest for my...

    controlling the lenght of a signal using an AND gate and a flip-flop?

    my idea is that you send a signal to set the flip-flop to HIGH and send the same signal to an AND gate with a resistor to delay it, before it resets the flip-flop to LOW... and thus one should be able to control the lenght of a signal. would this work? i've had very little luck and...

    How to read TMR0L and TMR0H registers together to create a delay?

    Using PIC16F18446 TMR0 module to create a 1 second delay WITHOUT the use of the interrupts. Here is the program so far: void main(void) { // Oscillator Settings: // HFINTOSC 8 MHz OSCCON1 = 0b01110100; OSCFRQ = 0b00000011; // Data Direction Settings TRISA =...

    Install timer delay in pump circuit

    I am looking to install a delay timer in a simple 12v circuit that supplies a well pump (6A) in a garden powered from a solar charged battery. I want the pump to run for 10mins when a circuit is closed on a toggle switch. If the pump is to restart after it has stopped, the toggle will need to...
