  • Multifunction Delay Trigger Chip Time Delay Relay Module IC Timing 2s -1000h DC 5V ()
    Dimension: 12 x 12mm
    Working Voltage: DC 2-5V
    Timing can be set to a minimum to a maximum of 2 seconds 1,000 hours

    Function and Design

    1. The circuit according to claim connected and set a good time resistance and supply voltage;
    2. Before the power not trigger output is high;
    3. Trigger terminal "falling" trigger effective immediately
    after the trigger output terminal goes low at the same time start the timer circuit;
    4. Set the timer time to recover after the output terminal is high, wait for the next "falling" trigger;
    5. The chip is not repeated triggered, meaning that
    continue to trigger in the period after the trigger chip output low if the trigger is invalid;
    6. The trigger end of "falling" Trigger refers to the instantaneous change from high level to a low level;
    7. General refers to VCC high voltage, low means 0-0.3v or GND,
    provided that they meet the level requirements can be;
    8. trigger terminal can be connected to touch switch or microcontroller IO port or
    other digital circuits have a "falling" can effectively trigger;
    9. The trigger can be designed to power, only to trigger a short circuit to ground, power is triggered,
    the time to recover after the output to a high level, waiting for the next
    Falling edge trigger again.
    Chip Features:

    1. The use of low-power CMOS technology, lead-free and environmentally friendly.
    2. Direct Push can output low LED
    (please add current limiting resistor), the output high may push transistor (please add current limiting resistor).
    3. Available resistance adjusting timing, there are 8 * N (N = times the timing selection,time can be adjusted from 2s-1000h.
    4. Optional trigger timing and triggering termination ground electric timer.
    5. standby output high, falling edge trigger, post-trigger output low, after the delay recovery high.

  • 3 amp motor controller with feedback (pololu) ()
    The 3-Amp motor controller with multiple interface and feedback options simplifies servo control of commonly available DC motors. The module features three independent interfaces: a serial protocol for microcontroller-based applications, a pulse-width interface for connection to hobby radio control equipment or serial servo controllers, and an analog voltage interface for simple tests and demonstrations. Two feedback alternatives allows for closed-loop control of position or speed.
