Concept
Seven segments + colon, driven by TM1637.
A little theory
Each digit is 7 LEDs + DP. Chip handles multiplex. In the classroom, treat TM1637 4-Digit 7-Segment Clock Display as a beginner part using 2-wire (CLK/DIO). Typical India street price is about ₹50–₹100. Always verify voltage and pin labels on your exact module — silk screens vary across clones. Start with a datasheet or trusted learn guide, power the part correctly, share GND with the MCU, and test with a simple blink/read sketch before building the full project. Measure voltages with a multimeter when something fails, and keep actuator current off the MCU regulator.
