Arduino Motion Sensor – Circuit and Working The circuit diagram of the automation device using a motion sensor is shown in Fig. 2. It consists of an Arduino Nano board (MOD1), a PIR sensor (S1), a ...

The INA219 is a voltage, current and power measurement device. A few important maxima, see datasheet, chapter 7, esp 7.5 Datasheet states it supports 1 KHz .. 2.56 MHz. Note: higher speeds and longer ...

Light sensor Dark sensor. Light and dark detection using an LDR. For this project, let’s stick to the LDR sensor module so we can select the light or dark detection by placing jumpers. We’ll be using ...

To test it out, you do not need Arduino. Connect the Signal & Ground pin of the EMG Sensor to a Multimeter set to DC Voltage Measurement. First measure the voltage without connecting the electrodes, ...

Working of LDR controlled LED using Arduino. As per the circuit diagram, we have made a voltage divider circuit using LDR and 100k resistor. The voltage divider output is feed to the analog pin of the ...
