The 555 Timer Design

Create an innovative 555 design today, the 555 should be the heart of the circuit.

555 timer Design
Here are some pages having 555 design ideas that will help you learn quickly. Then create your own design, be original. Learn and Do-it-Yourself or DIY. Better still CIY - Create it Yourself. Be Creative.

CAn Remote Automation-Control with AVR

CARACA is a home automation project based on a net of interconnected programmable circuits suited to perform different tasks like switch on/off appliances, decode commands from Ir remote control units, control thermostats, measure temperature and more.

CAn Remote Automation-Control with AVR

Every node of the net communicate each other through a robust protocol (CANBus), and the status can be monitored by a PC possibly connected to the Internet.

Simple 555 Simulation Software

Each provides an array of design wizards, circuit blocks and information panels that facilitate the use of the 555 timer in projects. Component value calculations for the 555 take into account the supply voltage, timer fabrication (CMOS or Bipolar), and, where appropriate, load currents.

555 Timer Project Design Software for Beginners and Experts

555 Timer Project Design Software for Beginners and Experts

22 timer design wizards - 14 for the astable mode, 8 for the monostable mode

input circuitry - for gating an astable or triggering a monostable. Input categories are switch, touchplate, continuity, liquid level, AC detect, light, sound, and temperature.

counter wizards - facilitate divide by/count to strategies using common binary and decade counters
output circuitry - that can be activated by the 555 timer. Includes switching loads, driving motors, driving LEDs, lamps, numeric and bargraph displays, and audio, ultrasound and RF outputs

555 Timer

This program allows you to calculate Resistor and Capacitor values for both Astable and Monostable modes.
