Welcome to the Electronics merit badge information page. During this merit badge at the March 2015 camp out we will:
- Explore the function and symbols of electronic parts.
- Diagram, analyze, build and improve an electronic control circuit.
- Learn how to solder various parts.
- Use test equipment: multi-meter, oscilloscope and logic analyzer.
When complete we should have an electronic circuit that flashes an LED.
- Read through the BSA Electronics pamphlet.
- Get a blue card from Mr McCowan
- Req 2a, see the attached PDF below for a copy of the schematic.
- Req 4b, Describe how a number system and logic gates make digital design possible. See pages 60-63.
- Req 4, design and build a circuit to properly count 0-5 and could be used as the die counter in Req 2. Using the parts CD4024, CD4049, CD4001, CD4011 attached below. I can provide the parts and breadboard. Optionally you can add in the LEDs.
