LED Dice Kit - Build a Random Dice with LEDs, a 555 Timer, and a 4017 Counter

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Press a button and seven LEDs light up to reveal a random dice number - no screen, no code, just pure electronics. This kit puts a 555 timer and a CD4017 decade counter in a child's hands, turning a classic dice into a glowing, button-operated gadget. It's a screen-free STEM activity that gives your 6-8 year old a first taste of how digital circuits create sequences and randomness.

What You'll Build

In about an hour, you'll have a breadboard circuit that mimics a real dice toss. Each time you press the button, the LEDs flicker rapidly and then settle on one of the six standard dice patterns - a single dot, two dots arranged diagonally, and so on. The result is truly random because the circuit runs at such a high speed that your button press catches a fleeting count. It's a compact, handheld device your child can play with immediately after building.

What You'll Learn

• How a 555 timer IC produces a steady train of pulses that drives the rest of the circuit.
• How a 4017 decade counter advances through its ten outputs, lighting only the LEDs that form dice faces.
• How to wire LEDs safely using current-limiting resistors so nothing burns out.
• How to assemble a durable circuit on a solderless breadboard with jumper wires.
