We redesigned our ELECTRONIC TIMER Kit. It is now a DUAL timer kit
based on the LM555 Timer Chip, a highly stable device for generating accurate
time delays or oscillation. when a switch is turned on or
off, mechanical bounce noise generates spurious pulses.
When operated in "mono-stable" mode, the EBTD-9
prevents these noise pulses from adversely affecting your
project. Use this circuit to set clocks or counters - any
time you need a push-button switch! Or, run the kit in
"a-stable" mode and learn how clock/timer
oscillator circuits work. Use this circuit to
"clock" other projects. Power requirement 5vDC,
size 2.25" x 2.75"
The NEW Designation for this Kit is EBTD-9
