Every configuration in one place: a proper schematic, a live gain calculator that redraws the component values, a Tinkercad build checklist, and a predict-the-output check — six labs, one page.
📋 How to use this page (and a quick Tinkercad refresher)
Work through the six tabs below in order. For each circuit: (1) adjust the calculator to see the gain equation and the schematic's labels update live, (2) build the circuit in Tinkercad Circuits following the checklist, (3) answer the predict-the-output question. A circuit is marked complete once every step is checked and the question is answered correctly — track your progress in the bar below.
Tinkercad Circuits is free, browser-based, and needs no install — search "Op Amp" in the components panel for the ideal block or a 741/LM358-class IC.
Every circuit here uses a dual ±12 V supply, matching the lesson's grapher clipping demo.
Drop a Function Generator and Oscilloscope onto the breadboard for every build — Ch.1 on the input node, Ch.2 on OUT.
