Wiring module on a breadboard Members who have completed their line following robot will begin work on this at our January meeting.
IR Schematic Exercise - this exercise is designed to teach members the function of each component of the IR module.
Wiring module on a circuit board Members who have completed wiring this module on the breadboard will use these instructions to complete the module to be attached to the robot. Work on this may start sometime in the spring, depending on how fast we progress on the breadboard work.
How does an IR TV remote work? This lesson explores the infrared control codes sent to a TV by an IR remote. Members should read this lesson after the "Wiring module on breadboard" lesson
Digital Modulation - how is digital information sent through a wire or the air?
We will start the Crystal Radio Project possibly at our June meeting.
Crystal Radio Project - Lesson 3 - This lesson completes the Crystal Radio project (except amplifier). Please read this as you near completion of your radio.
As part of the project, members will construct an audio amplifier for the crystal radio. The audio amplifier can also satisfy part of the requirements of the 4-H project book "Entering Electronics." The last activity in the "Entering Electronics" book is also an audio amplifier. Unfortunately, the integrated circuit specified in the activity is no longer available. Another IC chip, LM386, can be substituted for the obsolete chip, but requires a different circuit. Instructions for the audio amplifier with LM386 IC are available at the link below. Parts for completing the project are available from Mr. La Favre.
