A similar relaxation oscillator can be built with a 555 timer IC (acting in astable mode) that takes the place of the neon bulb above. That is, when a chosen capacitor is charged to a design value, (e.g., 2/3 of the power supply voltage) comparators within the 555 timer flip a transistor switch that gradually discharges that capacitor through a ...

Just days after the USDA issued a new order that all raw milk must be tested for bird flu, reports have emerged of animals dying of the virus, including cats and several zoo animals.
For example, the positive (and/or negative) pulse width from a 555 Timer IC in monostable or astable mode represents the time it takes to charge (and/or discharge) its capacitor from 1 ⁄ 3 V supply to 2 ⁄ 3 V supply. By sending this pulse into a microcontroller with an accurate clock, the duration of the pulse can be measured and converted ...
