Classic Control course
Wire contactor and motor circuits by hand, wire by wire, and the course tells you whether it's right, and why.
The first two lessons and lesson 5 are free, no account needed
The lessons are in Arabic for now; the English version is on the way. Device screens and codes are the same as on the real hardware.

9lessons, from simple devices to star/delta and soft starters
24practical exercises you wire and the course checks
1completion certificate with a verification code
IECIEC and NEMA symbols next to the real device
Classic control
What you'll learn
- Know every panel device: push buttons, selectors, E-stops, limit switches, lamps
- Understand auxiliary relays, seal-in and interlocks
- Wire the power and control circuits of a DOL motor starter
- Choose protection properly: fuses, MCBs, overloads and MPCBs
- Use on-delay, off-delay and cyclic timers in real circuits
- Read a 3-phase motor nameplate and wire the terminal box in star or delta
- Reverse a motor with interlocks, and build sequences and jogging
- Wire automatic star/delta, braking methods and soft starters

The lessons
In order. Every lesson has a short explanation, hands-on experiments and questions.
- Simple control devicesFreeSwitch, selector, push button, E-stop, limit switch, lamp and supply
- Auxiliary relays and seal-inFreeCoil and changeover contacts, 8/11/14-pin relays and sockets, latching, and interlocks
- The contactorPower and auxiliary contacts, AC-1/AC-3, power and control circuits, and DOL with seal-in
- Protection: fuses, breakers, overloadsFuse types, MCB curves B/C/D, the thermal overload (Ir, class 10, 95-96 and 97-98, phase loss), MPCBs, and protecting a DOL circuit
- TimersFreeOn-delay, off-delay, cyclic and multi-function timers, and timer circuits: sequences, loops, the cart and the pump (practicals 14–24)
- The 3-phase induction motorConstruction and the rotating field, the nameplate, star and delta terminal boxes, direction, power and current tables, cable size
- Pressure, level switches and sensorsPressure switches, float switches, PNP/NPN proximity sensors and photocells, in pump, compressor and conveyor circuits
- Sequences, jogging and reversing (5–13)Conditional starts, sequences, jogging, reversing with interlocks, a hoist with limit switches, and a lathe (practicals 5–13)
- Advanced: star/delta, braking, HVAC, soft startersAutomatic and manual star/delta with a Y-Δ timer, DC and plugging braking and mechanical brakes, a central A/C compressor circuit on 24 V, and soft starters with bypass
Who it's for
Who this course is for
- Technicians and electricians who want to understand the panel, not just copy it
- Technical school and electrical engineering students
- You have a plant or maintenance job interview coming up
- Before you start on VFDs and PLCs
FAQ
Before you ask
Do I need a background first?
It helps to know voltage, current, series and parallel. If not, take the electrical basics course first and come back.
How does the wiring work?
You drag a wire from terminal to terminal on a board like a real panel, then switch on. If something's wrong, the course shows where and why.
Is there a certificate?
Yes. When you finish every lesson and the final exam while signed in, you can get a Course Completion Certificate with a verification code and QR code. It confirms you completed the course; it is not an accredited qualification.
Is the course free?
The first two lessons and lesson 5 are open to everyone, no account needed. The other lessons need a free account you can create in seconds with your email.
Does it work on a phone?
Yes. The board fits small screens, but wiring is more comfortable on a tablet or computer.
