Sometimes we want to know the current draw of a device for various reasons. One reason would be to estimate the run time of the device when it is running on batteries. It is often very inconvenient to try to break the battery connections and insert a current meter or sense resistor, so here is an alternate method that does not require breaking the current flow.

The 555 timer is capable of producing accurate timing ranges from microseconds to hours and therefore has many practical uses for every level of electronics. It is an especially good integrated circuit for electronic hobbyists to learn with. I will guide you through the basics and will also show you an example circuit.
Some features:
- Operates on a range of supply voltages
- Timing from micro seconds to hours.
- Monostable and astable operation
- Adjustable duty cycle
- High output
