Everyday Microcontrollers and Robotics
Discover how tiny computer chips bring modern gadgets, appliances, and medical monitors to life. Learn to connect sensors, drive motors, and write clean control logic to turn electronic parts into working automated machines.
Like Duolingo, but for Everyday Microcontrollers and Robotics. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
20 levels across 3 sections, about 40 minutes end to end, roughly 8 days at five minutes a day. It moves through Making Things Move and React, Reading the Body and Environment, and How Smart Machines Think and Operate. It starts from scratch.

Key ideas in Everyday Microcontrollers and Robotics
- A microcontroller interacts with the physical world by reading incoming voltages as inputs or setting outgoing voltages as outputs
- Sensors and buttons send voltage signals into the microcontroller to be checked
- Actuators like LEDs, buzzers, and motor drivers receive voltage commands sent out by the microcontroller
- Setup code configures pins and hardware settings only once right when the board powers up
- The main loop runs repeatedly forever as long as the board has power
- Checking inputs and updating outputs belongs in the loop so the device can respond continuously
- LEDs offer very little resistance on their own once they turn on
- A series resistor limits the amount of electrical current flowing through the circuit to a safe level
- Without a current-limiting resistor, excessive current will permanently destroy the LED and potentially damage the microcontroller pin
- A digital input pin left disconnected acts like a tiny antenna that picks up stray electrical noise, known as floating
- A floating pin unpredictably jumps between reading HIGH and LOW
- A pull-up or pull-down resistor gently anchors the pin to a known voltage (supply or ground) when the button is open
- Digital output pins can only output maximum voltage (HIGH) or zero voltage (LOW)
- Switching a pin HIGH and LOW thousands of times a second creates an average voltage that our eyes or motors perceive as smooth analog levels
- Varying the fraction of time the signal spends HIGH (the duty cycle) controls brightness or motor speed
- Microcontroller pins only supply small logic signals (typically a few tens of milliamps at 3.3V or 5V)

Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Everyday Microcontrollers and Robotics the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
