Start here: learning paths in electronics, control and robotics

Path 1 · Understand a simple circuit

Start with voltage, current and resistance. Aim to explain why a result changes when a load is connected or a different component is chosen.

By the end: explain why 2.5 V without a load does not guarantee 2.5 V with a device connected.

Path 2 · Understand time and control

You should recognize units and substitute values in formulas. Start with a curve with a known response, then compare the effect of feeding a process’s output back to its controller.

By the end: distinguish a slow response from a setpoint the plant cannot reach.

Path 3 · Turn commands into motion

Use ratios, angles and time units. Follow numeric speeds even when animation is slowed to make motion visible.

By the end: explain why more commands per revolution do not mean more speed.

Use it in class or for independent study

Before moving a control, write a prediction and identify what will remain fixed. Record the values, describe the change and compare it with the formula. If a result is surprising, check units and initial conditions before trying again.

Experiments check a prediction and include an explanation readable without JavaScript. Grades and answers are not stored; reloading resets the activity. Expandable solutions support checking reasoning without locking access to the tool.

For a logic activity, combine truth tables ↗ with bits and their positions ↗. Predict a state or number before toggling the switches.
