DFPlayer - working - amp failed

2/3 Received SD cards - loaded Girls file - will add more Then test Ard player 2/4 used https://www.youtube.com/watch?v=mL0epDFNHqY&t=709s&ab_channel=RachelDeBarros https://racheldebarros.com/arduino-projects/trigger-sound-effects-with-arduino-pir-motion-sensor/ diff pin settingd - No Just a buzz on thew speakers Next try https://www.youtube.com/watch?v=PBdqgHj_AkU&t=11s&ab_channel=TheLastOutpostWorkshop 2/10 confirm file structure ok - ? 2/12 tried ck wiring - prob not probMP3 files good, speakers good, file dir or code prob 2/17 Built common emitter AMp Failed - no sound - on hold till I test an Amp w/ tones 2/25 Working but little sound - new player same as last one Need amp! Different hookup https://www.youtube.com/watch?v=P42ICrgAtS4&ab_channel=Indrek MOSFET AMP https://www.youtube.com/watch?v=ncu1Ep2Um2A&ab_channel=GreatScott%21 or N-channel MOSFET (e.g., IRF520 or IRL540) 100 μF electrolytic capacitor 1 kΩ resistor Speaker (8Ω or higher impedance) Arduino board Circuit Design Connect the Arduino's PWM output pin (e.g., pin 9) to the gate of the MOSFET through the 1 kΩ resistor14. Connect the source of the MOSFET to ground. Connect the drain of the MOSFET to one terminal of the speaker. Connect the other terminal of the speaker to the positive voltage supply (5V from Arduino or an external power source for higher volume). Place the 100 μF capacitor between the Arduino's PWM pin and ground to filter the PWM signal14. The IRLZ24NPBF is an excellent choice for use with Arduino and other microcontrollers. Here are the key features that make it suitable:( from Amazon) https://www.amazon.com/dp/B0CBKDKT9Z?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1&th=1 1. It's a logic-level MOSFET, designed to work with low gate voltages like those from microcontrollers[2][4]. 2. The IRLZ24NPBF can be fully turned on by 5V from an Arduino, making it compatible with both 3.3V and 5V logic systems[3][5]. 3. It's an N-channel MOSFET in a TO-220 package, capable of handling up to 18A continuous drain current[1][2]. 4. The maximum drain-to-source voltage is 55V, making it suitable for a wide range of applications[1]. 5. It hasa low on-resistance (RDS(on)) of 60mΩ at 11A and 10V gate-source voltage, which means it's efficient and generates less heat when conducting[2]. 6. The IRLZ24NPBF is commonly used in applications such as DC motors, inverters, SMPS, lighting, load switches, and battery-powered devices[1]. 7. It's particularly well-suited for Arduino projects involving LED control, motor driving, and other high-current applications[3][5]. Given these characteristics, the IRLZ24NPBF is indeed a good choice for Arduino projects, especially when you need to control higher voltage or current loads using PWM or digital signals from your microcontroller.
