In this project, I'll make a small circuit capable of controlling a servo, it is a servo tester made out of a 555 timer IC.

[R-B] designed a 555 timer circuit to scan a keypad. Keypads are common interfaces for small projects and require row and column scanning by a microcontroller. [R-B’s] setup allows you to reduce the ...

You can use a microcontroller to build a clock. After all, a clock is just something that counts the passage of time. The only problem is that microcontrollers can’t track time very accurately. They ...

The project makes use of a monostable 555 timer circuit and a relay to drive the load in order to create an aquarium feeding timer. The setup of the circuit is a one shot trigger or timer where the 55 ...

Today we are going to create a strobe light for the tips of the wings of an rc airplane using a 555 timer (NE 555 or lm 555 IC) this circuit is very easy to make with few components and most ...

Applications of commercially available integrated timers, including the NE/SE555, are fairly limited when used in their monostable mode. This is due to their inability to function with all types of ...

The venerable 555-type timer makes an effective driver for power MOSFETs, but you have to understand the drive situation when selecting the correct variation of the basic timer. This idea shows how ...

Sure, there have been some pretty creative variations on the standard paper business card, but if you're looking to make a career in electronics engineering, card stock isn't necessarily the best ...

Used in a variety of timer, pulse generation, and oscillator applications, the 555 was designed in 1971 by Hans Camenzind. A favorite for many engineers, the 555 is still in widespread use due to its ...
