A multimeter or a multitester, also known as a VOM (Volt-Ohm meter), is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter would include basic features such as the ability to measure voltage, current, and resistance.

Analog multimeters use a microammeter whose pointer moves over a scale calibrated for all the different measurements that can be made. Digital multimeters (DMM, DVOM) display the measured value in numerals, and may also display a bar of a length proportional to the quantity being measured.

Digital multimeters are now far more common than analog ones, but analog multimeters are still preferable in some cases, for example when monitoring a rapidly-varying

As the name suggests it is the multifunction device for all your testing need for daily work.

When testing DC voltage, AC voltage, DC current, resistance, diode, buzzer, and battery, connect the red test lead to “VΩmA” jack and black test lead to “COM” jack, whereas When you need to test the current more than 200mA, connect the red test lead to “‘ 10A≡” jack and black test lead to “COM” jack. And When while testing the temperature, connect the temperature probe to “VΩmA” jack or “COM” jack.

When testing the magnifying ratio of the transistor, turn the switch to hFE position and connect the transistor to the eight hole jack available in blue color. For the Square wave output, the frequency is 50Hz, the voltage is approximately 3Vp-p. The output jack is “VΩmA” and “COM”

PCA9685 16 Channel 12 Bit PWM Servo Motor Driver,  If you want to make a robot which has lots of moving parts or if you want to control too many LEDs with PWM outputs,  then the limited PWM outputs of your microcontroller would be a big problem for you. To overcome this problem, the only thing you should do is to get a PCA9685 16 Channel 12 Bit PWM Servo Motor Driver.

You can control 16 free-running PWM outputs with 16-Channel 12-Bit PWM/Servo Driver using only 2 pins. You can even chain up 62 breakouts to control up to 992 PWM outputs.

PCA9685 16 Channel 12 Bit PWM Servo Motor Driver an I2C-controlled PWM driver with a built-in clock. That means you do not need to continuously send it to signal to tie up your microcontroller, it is completely free running!

It is 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs. This is good when you want to control white or blue LEDs with 3.4+ forward voltages. 6 address select pins so you can wire up to 62 of these on a single I2C bus, a total of 992 outputs.

Features :

1. Adjustable frequency PWM up to about 1.6 KHz
2. 12-bit resolution for each output – for servos, that means about 4us resolution at a 60Hz update rate
3. Configurable push-pull or an open-drain output
4. The output enable pin to quickly disable all the outputs
5. Terminal block for power input
6. Reverse polarity protection on the terminal block input
7. Green power-good LED
8. 3 pin connectors in groups of 4 so you can plug in 16 servos at once
9. Chainable design
10. A spot to place a big capacitor on the V+ line
11. 220-ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial.
12. This board/chip uses I2C 7-bit address between 0x60-0x80, selectable with jumpers.
