Learn, Practise, and Simulate Electronics.

Electronics is usually taught with static diagrams. You can read the whole page on a 555 astable, follow every line of the derivation, and still not know what actually happens when you halve R2 — because nothing on the page moves. The gap between understanding a formula and understanding a circuit is where most people get stuck.

MakersDeck closes that gap by pairing every explanation with something you can drive. Change a resistor and watch the duty cycle shift. Open a valve and watch the tank fill. Toggle an input and watch the rung energise. The simulators are not decorations bolted onto an article — they run real models, and the numbers they show are computed, not canned.

What is inside

Subjects cover DC circuits, AC circuits, digital logic, semiconductor devices, analog electronics and power electronics. Each breaks into topics, and each topic runs the same four stages: read the theory, work through a solved example, drive the simulator yourself, then answer graded questions to check what stuck.

Three full simulators go deeper than a single topic needs. The PLC simulator has ladder and Function Block Diagram editors plus a live HMI process screen, so you can write a rung and watch a tank, pump and float switch respond to it. The circuit simulator is a schematic editor on a real SPICE engine with DC, AC and transient analysis. The logic simulator builds gate networks and generates truth tables, Boolean expressions and K-maps from whatever you wire up.

The toolkit is 45+ focused calculators — resistor and capacitor codes, filter design, op-amp gain, 555 timing, PCB trace width — each one showing the formula it used and a worked example, not just an answer box. Articles go deeper on subjects that deserve more room than a topic page: motor types, sensor interfacing, MOSFET switching, PWM, I²C and SPI.

Who it is for

Students who need a second explanation after the lecture. Teachers who want a simulator to project rather than a slide of a circuit. Makers and hobbyists who can build the thing but want to know why the value is 4.7 kΩ. The material assumes curiosity rather than a degree, and every topic starts from what the symbols mean.

Everything is free and runs in your browser. There is no account to create, nothing to install, and no paywall between you and a simulator. Your saved circuits, quiz results and progress are stored on your own device and are never uploaded — the site works offline once loaded, and closing the tab does not send your work anywhere.
