Free electronics for kids in 30 short lessons — a simple circuit for kids, conductors, switches, cells, series and parallel circuits, Ohm’s law for kids, resistor colour codes, LEDs, power, microcontroller boards, sensors, tiny programs and IoT for students, with fresh questions every time. Each lesson has a clear method, a worked example, “Show me how” help, a 20-question test, a badge, printable worksheets with answers and free certificates — and safety first: only small battery kits, always with an adult.
🔌 Quick check: Electricity and energy
Each lesson has the idea, a worked example, unlimited practice with “Show me how”, a 20-question test and worksheets. Pass a lesson’s test to earn its badge; pass every lesson in a part to earn that part’s certificate (sign in to keep badges, certificates and progress).
Ages 9–11 — electricity and energy, electrical safety, conductors and insulators, open and closed circuits, switches, cells and batteries, circuit symbols, series and parallel circuits and a Part 1 test.
Ages 11–14 — voltage, current and resistance, Ohm’s law, resistors in series and parallel, the resistor colour code, LEDs, components, electric power, electricity units and a Part 2 test.
Ages 12–16 — what a microcontroller is, input and output pins, blink programs and delays, if / else with sensors, loops and variables, sensors and actuators, the Internet of Things, IoT safety and privacy, project planning and the final test.
Electronics is the science of making electricity do useful jobs — light a bulb, ring a buzzer, spin a motor or let a tiny computer decide what to do. In Part 1 children learn where electricity comes from, how to stay safe (home mains at 230 V is never used for projects), which materials are conductors and insulators, why a bulb glows only in a closed circuit, how switches work, how cells add up in series, the circuit symbols, and the difference between series and parallel circuits. In Part 2 they meet voltage, current and resistance, use Ohm’s law (V = I × R) with friendly numbers, add resistors in series and parallel, read the resistor colour code, light an LED the right way round with its resistor, and work out power (P = V × I) and the units on an electricity bill. In Part 3 they learn what a microcontroller is, input and output pins, digital and analog signals, read tiny programs with blinks, delays, if / else and loops, choose sensors and actuators, and discover the Internet of Things (IoT) — smart-home devices that send data over Wi-Fi to an app — with its safety and privacy rules, ending with planning a project as input → process → output. Everything is learnt on paper and screen; any hands-on building uses a low-voltage battery kit with an adult.

Electronics for kids teaches how electricity makes things work — simple circuits, conductors and insulators, switches, cells, series and parallel circuits, Ohm’s law, resistors, LEDs, power, and then microcontroller boards, sensors, tiny programs and the Internet of Things (IoT). This free course has 30 short lessons with practice, tests and worksheets.
रोज़ 10–15 मिनट एक छोटा पाठ करें। पहले तरीका और उदाहरण साथ पढ़ें, फिर 10 सवाल हल करवाएँ और गलत जवाब पर “Show me how” दबाएँ। अगर घर पर कुछ बनाना हो तो सिर्फ़ छोटे बैटरी सेल (9 V तक) वाला किट और किसी बड़े की निगरानी में — घर के बिजली सॉकेट (230 V) का इस्तेमाल कभी नहीं।
Yes, when done the safe way. This course is learnt on paper and screen. If your child builds anything, use only a low-voltage battery kit (cells up to about 9 V) with an adult nearby. Never use mains sockets, never touch switches with wet hands, keep water away, and stop if any part gets hot.
Ages 9 to 16. Part 1 (electricity basics) suits ages 9–11, Part 2 (components and Ohm’s law) ages 11–14, and Part 3 (microcontrollers and IoT) ages 12–16. Older children can start anywhere and revise with the tests.
No. Every lesson, test and worksheet works without any hardware — children learn the ideas, do the calculations and read simple circuits and programs. A beginner microcontroller board or a small battery kit is a nice extra for hands-on practice with an adult, but it is not needed.
With identical bulbs and ideal wires: in series there is one path, so removing one bulb puts all of them out and the bulbs share the voltage; in parallel each bulb has its own path and gets the full voltage. Children answer “does it glow?” and “how many glow?” questions and work out the volts and current.
Sign in and pass the 20-question test of a lesson (16 or more right) to earn its badge. Pass every lesson of a part — Part 1 is lessons 1–10, Part 2 is 11–20, Part 3 is 21–30 — and you get that part’s certificate, with a code anyone can check.
Yes. All 30 lessons, practice, tests, worksheets, badges and certificates are free. Classes with a TalentJR teacher (online or at home) are paid — request a call back for fees.
