Along with the voltage you need to check the polarity of the device and the powerpack<br>

<br>
The polarity of the adapter cord and plug must match the polarity of the device, meaning that the positive contact of the plug must mate with the positive contact in the receptacle, and the negative plug contact must mate with the negative receptacle contact. Since there is no standardization of these plugs, a polarity symbol is typically printed on the case indicating which type of plug is needed.

=MCP3008 ADC-DAC=
Features and Specifications
*8-Channel 10-bit ADC IC
*Communication protocol: Serial SPI interface
*Operating voltage 2.7V to 5V
*ADC method: Successive Approximation (SAR)
*Sampling Rate: 200ksps and 75ksps for 5V and 2.7V resp.
*Available in 16-pin PDIP, and SOIC packages
<br>
The MCP3008 is an 8-Channel 10-bit ADC IC, so it can measure 8 different analog voltage with a resolution of 10-bit. It measures the value of analog voltage from 0-1023 and sends the value to a microcontroller or microprocessor through SPI communication. It can operate on both 3.3V and 5V and hence it can be used with 5V microcontroller as well as with 3.3V systems like the Raspberry Pi. It uses the SAR method to convert the Analog voltage to digital value; it might not be the fastest and precise ADC in the market but is the cheapest and easy to use one.

=Light Intensity Sensor Photosensitive Resistor Module=
Features:
*Sensitive photoresistor sensor
*Comparator output, clean signal, good waveform, strong driving capability, more than 15mA.
*Adjustable potentiometer to adjust the brightness of the detected light
*Working voltage 3.3V-5V
*Output form: digital switching output (0 and 1)
*Fixed bolt holes for easy installation
*Small board PCB size: 3.2cm x 1.4cm
*Use wide voltage LM393 comparator

Module instructions:
The photoresistor module is most sensitive to ambient light and is generally used to detect the brightness of ambient light, triggering a microcontroller or relay module, etc.
When the brightness of the ambient light reaches the set threshold, the DO end outputs a high level, and when the ambient light brightness exceeds the set threshold, the DO end outputs a low level;
The DO output terminal can be directly connected to the single chip microcomputer, and the high and low levels are detected by the single chip microcomputer, thereby detecting the change of the light brightness of the environment;
The DO output can directly drive the relay module of the store, which can form a light control switch.
Product wiring instructions:

*VCC is connected to the positive pole of the power supply 3.3-5V
*GND is connected to the negative pole of the power supply
*DO TTL switch signal output
