Arduino is a Guy

"Arduino will then stop talking about himself in the third person."

Apperently Arduino is a guy and illeistic too.

Electronics Merit Badge

This last Saturday I had the opportunity to volunteer to teach a few Boy Scouts the Electronics merit badge.

We had a good time talking about various electronics components, building and soldering an electronic kit.

The kit we put together was a noisy little police siren kit. Amazingly all of the boys were able to complete their kits without frying any transistors or IC chips.

We also got to play with a Metcal station which did a consistent and amazing job with the soldering tasks.

Electronics merit badge requirements

It must show resistors, capacitors, and transistors or integrated circuits, Use the correct symbols. Label all parts. b. Tell the purpose of each part. 3. Do the following: a. Show the right way to solder and desolder. b. Show how to avoid heat damage to electronic components. c. Tell about the function of a printed circuit board. Tell what precautions should be observed when soldering printed circuit boards. 4. Discuss each of the following with your merit badge counselor, and then choose ONE of the following and build a circuit to show the techniques used: a. Tell how you can use electronics for a control purpose, and then build a control device circuit. b. Tell about the basic principles of digital techniques, and then build a digital circuit. Show how to change three decimal numbers into binary numbers, and three binary numbers into decimal numbers. c. Tell about three audio applications of electronics, and then build an audio circuit. Show how to read the schematic diagram of the project you choose and, to the best of your ability, explain to your counselor how the circuit you built operates. 5. Do the following: a. Show how to solve a simple problem involving current, voltage, and resistance using Ohm's law. b. Tell about the need for and the use of test equipment in electronics.
