Proposed course content
5 sections · 10 illustrative lesson records
Circuit and board foundations2 lessons
- Introduction to robotics and safe prototypes
Identify the input, control and output stages of a small robot. Review board connections, low-voltage power requirements and the limits of a supervised prototype. The robotics introduction video has not been supplied.
Public player demonstration - Safe connections and a first program
Plan a breadboard circuit, check pin assignments and voltage compatibility, then outline a simple program that reads an input and controls an indicator.

Sensors and observations2 lessons
- Reading digital and analog sensors
Compare digital states with analog readings. Choose an appropriate input pin, record sensor observations and distinguish a raw reading from a calibrated measurement.
Enroll to access · Video not supplied - Sampling and noisy measurements
Inspect how sampling interval, wiring and environment affect a sensor reading. Record repeated observations and explain the limits of basic smoothing.

Simple motion control2 lessons
- Motor drivers and bounded movement
Explain why a motor needs a suitable driver and separate power considerations. Outline direction, speed and bounded movement commands before testing hardware.
Enroll to access · Video not supplied - Power budgets and safe stopping
Check the current requirements of the motor and controller, define a stop condition and plan how to respond to a stalled motor or an unexpected input.

Connected data2 lessons
- Device messages and sensor logging
Structure a small sensor message and record readings with timestamps. Compare local device communication with a simple data log and identify missing fields.
Enroll to access · Video not supplied - Handling missing data and connection failures
Define what the prototype should do when readings are stale or communication stops. Plan bounded retries and preserve a safe output state while recovering.

Prototype and documentation2 lessons
- Combining sensing, output and a data log
Connect a sensor reading to a bounded output and a local log. Test each stage separately before running the complete low-voltage prototype.
Enroll to access · Video not supplied - Documenting tests and limitations
Record circuit connections, program configuration and test conditions. Summarize observations, unresolved faults and limitations without claiming production readiness.
