Feb 12, 2020 · I was hoping to connect the LM358 Amplifier Module (Adjustable Gain up to 100x) to my sensor in order to increase the output signal. The wiring of the op amp module seems very simple. However, when I connected everything the output changed to a range of around 450-550.

Feb 23, 2017 · The problem is the amps are so small i get zeros on analog pins, so i am trying to amplify it with LM358 Amplifier Module (www.openimpulse.com/lm358-amplifier-module). I have very simple circit now, just to try to find out how exacly it works.

Jul 21, 2013 · Hi, can anybody help me connect a condenser mic to a LM358 module to the Arduino. I have a LM358 module like the one at I have the VCC and GND connected and the power led comes on but no matter how I connect the IN a…

This tutorial will show you how to create that analog voltage using an LM358 or any other simple OpAmp along with a resistor and a capacitor that will create a low pass filter.

Arduino Watchdog With LM358 Op-Amp: This is a simple schematic that allows the use of the chip LM358 Op-Amp as a Watchdog for the Arduino board.

Sep 20, 2021 · Using an electret microphone, the Arduino can detect sounds and perform actions based on the input it receives. For example, the sound of hands clapping, a door closing, or someone’s voice can all be used to trigger an Arduino’s output.

Dec 8, 2020 · Here’s a circuit diagram that can be switched as the light and dark sensor… This example uses an LM358 dual-operational amplifier IC. As per the above circuit, the output of the LDR-resistor network is connected to the non-inverting input of one of the op-amps and inverts the input of another LM358 op-amp.

In the last two Instructables, I showed you how to how to make a Tilt sensor, Vibration sensor and how to make a Touch sensor. In this instructable, I'm going to show you How to design your own light sensor, which could be used as a day and night switch or as a part of a security system.

Aug 13, 2022 · As I mentioned before, the device is relatively simple to build and contains several components: - Arduino nano microcontroller. - LM358 low signal amolifier module. - Power mosfet transistor (in my case STP65NF06, but you can use any Power mosfet, for example IRF630) - Two potentiometers 10K ohms. - Buzzer. - Led.

we can us the amplifier module to increase the signal output that can be read. Instead of directly connecting AO pin to the arduino, connect it to the IN pin of the amplifier module.
