I need to build a blinking LED to simulate a apartment security system :thinking_cirno:

    555 timer IC
    
    The 555 timer IC is an integrated circuit used in a variety of timer, delay, pulse generation, and oscillator applications. It is one of the most popular timing ICs due to its flexibility and price. Derivatives provide two (556) or four (558) timing circuits in one package. The design was first marketed in 1972 by Signetics and used bipolar junction transistors. Since then, numerous companies have made the original timers and later similar low-power CMOS timers. In 2017, it was said that over a billion 555 timers are produced annually by some estimates, and that the design was "probably the most popular integrated circuit ever made". History The timer IC was designed in 1971 by Hans Camenzind under contract to Signetics. In 1968, he was hired by Signetics to develop a phase-locked loop (PLL) IC. He designed an oscillator for PLLs such that the frequency did not depend on the power supply voltage or temperature. Signetics subsequently laid off half of its employees due to the 1970 recession, and development on the PLL was thus frozen. Camenzind proposed the development of a universal circuit based on the oscillator for PLLs and...

  @sun friend gave me Arduino, but I never programmed this

  @kaia blinking an LED isn't too hard, tbh a lot of arduino projects are difficult like putting together a puzzle

  555 might be more approachable

    Multivibrator
    
    A multivibrator is an electronic circuit used to implement a variety of simple two-state devices such as relaxation oscillators, timers, latches and flip-flops. The first multivibrator circuit, the astable multivibrator oscillator, was invented by Henri Abraham and Eugene Bloch during World War I. It consisted of two vacuum tube amplifiers cross-coupled by a resistor-capacitor network. They called their circuit a "multivibrator" because its output waveform was rich in harmonics. A variety of active devices can be used to implement multivibrators that produce similar harmonic-rich wave forms; these include transistors, neon lamps, tunnel diodes and others. Although cross-coupled devices are a common form, single-element multivibrator oscillators are also common. The three types of multivibrator circuits are: Astable multivibrator, in which the circuit is not stable in either state —it continually switches from one state to the other. It functions as a relaxation oscillator. Monostable multivibrator, in which one of the states is stable, but the other state is unstable (transient). A trigger pulse causes the circuit to enter the unstable...

  @sun @kaia We had some guys do Arduino lights for some stage props including a jukebox that would change modes when buttons were pressed. From what I was told there are a lot of presets available so all you have to do is look at those and possibly tweak them to your liking. I kinda want to try doing something with Arduino sometime.

  @kaia @sun at least on amazon raspberry pi pico is actually cheaper than arduino

  @moth_ball @kaia It's quite fun. Here's a project I did to make the lights for a Ghostbusters proton pack replica.

  @sun @kaia When I was a boy, we built blinking LEDs with 2 transistors in a "multi-vibrator" configuration. Our fathers built them using an RC integrator and magic.

  @kaia @sun I built an inclinometer for a Jeep once. It's a board that has an accelerometer, driven by the same CPU that Artuino uses, although I used ATtiny85 for some random reasons. LEDs indicate how off vertical you are. It worked great! Once I got this out of my system, I uploaded the design to my website and returned to software.
