Hi all, I’m new to electronics tinkering and am looking to make a miniature megaphone (that’s the best way to describe it). An important aspect is that it must be mobile - AKA can’t be connected constantly to a power supply. I was looking on sparkfun’s website for products to help me make this. I found the following but am unsure about a microphone to get it to work:
SparkFun Mono Audio Amp Breakout: https://www.sparkfun.com/products/11044
Speaker - 0.5W (8 Ohm): https://www.sparkfun.com/products/9151
Battery Supply: https://www.sparkfun.com/products/10891
Any recommendations for the setup and a microphone? Do these seem like good products for my project? Thanks for the help!
