Morse code STEM activity
Morse code STEM activity Kids can build a basic telegraph circuit and engage in offline code-breaking challenges. These hands-on activities blend electrical engineering, logic, and a fun way to send secret messages. Hands-On Circuit Building Build a functioning telegraph system using basic electronics Components A 3V battery pack, an LED, a power buzzer, a push switch. Wire the components in a simple series circuit. When the switch is held down, it completes the circuit, allowing current to flow so the LED flashes and the buzzer sounds. The Coding: Use short presses for "dots" and longer presses (about 3 seconds) for "dashes" to spell out messages. Send secret messages for other group to decode. Compiled by Ms Naresh kuwar
