ECE Lab Kit 2: Build 555 Timer Astable, Monostable & Bistable Circuits with Oscilloscope Measurements

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

From CBSE Class 12 physics labs to B.Tech ECE oscillator experiments, this kit gives you everything to build the three fundamental 555 timer modes — astable, monostable, and bistable — and then see the results directly on an oscilloscope, measuring frequency, duty cycle, and pulse width exactly as prescribed in your lab manual. No chasing multiple suppliers; one box arrives and you are ready for your next practical session.

What You'll Build

By the end of a single lab session, you’ll have a stable astable oscillator blinking LEDs at a chosen frequency, a monostable pulse generator that triggers a single output pulse of adjustable duration, and a bistable flip-flop that toggles states. All three circuits can be probed with an oscilloscope to capture real-time waveforms and verify your calculated timing values.

What You'll Learn

• Configure the 555 timer as an astable multivibrator and calculate frequency and duty cycle
• Set up a monostable one-shot circuit and measure pulse width with an oscilloscope
• Build a bistable flip-flop and observe SET/RESET logic levels
• Use oscilloscope cursors to measure time intervals, voltage levels, and verify timer RC time constants

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Built for B.Tech ECE/EEE students who need to perform oscillator experiments as per university lab curriculum (VTU, AKTU, JNTU, and more), for CBSE Class 12 students exploring 555 timer applications in physics investigatory projects, and for ATL Tinkering Lab mentors guiding students through waveform measurements. If you already have an oscilloscope in your lab, this kit plugs right in and puts theory into practice.
