We can use this circuit in combination with digital development boards like Arduino for designing circuits where we need to activate the microcontroller by detecting a small pulse ... Testing our ...

Basic circuit board to output a 38 Khz ~51% duty cycle signal using a 555 timer in astable mode. The reset allows an arduino to drive logic at a lower rate for things such as sending 38KHz IR signals ...

555 Timer IC Based Square Wave Generator: First of all we will talk about 555 Timer IC based square wave generator, or should I say 555 Astable Multivibrator. We know that the capacitance of a ...

When the Arduino sends a heartbeat to the watchdog circuit, the heartbeat line is set to a low output, aka GND. This drains charge from C1 through R3, which in turn means that C1 is further away from ...
