FLICKER click

Thanks to the onboard NA556 dual precision timer from Texas Instruments and the G6D-ASI power PCB relay from Omron, the FLICKER click can control loads up to 5A, 250 VAC/30 VDC at a predefined time interval.

The on/off period can last from 0.1 to 6 seconds, that can be set by the two ON/OFF onboard potentiometers. The external load can be connected to the board through the screw terminal. FLICKER click runs on 5V power supply and it communicates with the MCU over RST pin.

DO NOT TOUCH THE BOARD WHILE THE EXTERNAL POWER SUPPLY IS ON!

Note: FLICKER click has exposed pins/pads. To stay safe take precaution when applying high voltage to the click. The click is to be used by trained personnel only when applying high voltage.

Programming

This code snippet configures required port E as digital, sets pins 1 and 2 as input and enters an infinite loop. While in an infinite loop, use potentiometers P1 and P2 to adjust the ON / OFF time period.

  • Supply voltage within range of 5 – 15 V.
  • Maximum output current detected : 225 mA.
  • Usable on : ARM, PIC, PIC32, AVR and FTDI compilers.
