Capacitors are one of the most widely used passive electronic components, and their performance depends heavily on the dielectric material used between their plates. The dielectric not only determines the capacitance value but also defines important characteristics such as stability,…
The 74×138 and 74×238 are popular 3-to-8 line decoders/demultiplexers used in digital electronics. Both ICs take 3 binary inputs and generate 8 outputs, but they differ in output type and enable configuration, which makes them suitable for slightly different applications.…
To set the output voltage of the LM317 adjustable voltage regulator, you use two resistors in a voltage divider configuration between the output and adjust pin. LM317 Output Voltage Formula To set the output voltage of…
Selecting the right microcontroller (MCU) is a critical decision when developing a commercial product. The MCU you choose will influence not only the product’s performance but also its cost, scalability, and time to market. A thoughtful selection process ensures your…
HOW TO DISPLAY TWO DIGIT NUMBER ON 7 SEGMENT using Arduino (RECOMMENDED METHOD) To display two digit number on 7 segment using arduino we need 2 seven segments and 2 shift registers IC 74HC595. Connect pin 9 of 74HC595 (which…
At some time or another you may run out of pins on your Arduino board and need to extend it with shift registers. This example is based on the 74HC595. The datasheet refers to the 74HC595 as an “8-bit serial-in,…
Every single pin of a microcontroller counts when designing advance integrated systems. Much of the task is solved by using I2C to connect the peripherals. We can further reduce the pin counts by using shift registers to drive 7 segment…
Electrical spacing rules become significant from a product safety perspective when the normal operating voltage is greater than 30VAC or 60VDC. It may come as a surprise that voltages above these levels are considered hazardous and that these designs are…
Interrupts plays a surprising role in a microcontroller program. And the ISR, Interrupt Service Routine is always ready to take the surprise challenge. But, ISR follows some guidelines and set of rules to properly execute the program. Recently I wasted…
As we know that Arduino contains ADC channels of 10-bit resolution. But if we require the measurement to be done with higher resolution then we can opt for the ADS1115 module. It contains 16 bit ADC with 4 channels and…
