DAC MCP4921 Interfacing with PIC Microcontroller PIC16F877A Digital and Analog is an integral part of Electronics. Most of the devices have both ADC as well as DAC and they are used when there is a need of converting signals either from analog to digital or digital to analog. Also the real world signals like sound and light are analog in the nature, so whenever these real world signals have to be used, the digital signals have to be… |

Send/Receive SMS with STM32F103C8 and SIM800C GSM Module GSM Modules are frequently used in IoT projects since it has the ability to send and receive data remotely. The GSM Modules doesn’t have much dependencies like the Wi-Fi modules. While other wireless modules such Wi-Fi or Zigbee have cons such as short range and cost, the GSM Module have the reliability, long range Since only one SIM card is required with valid plan. Though… |

Raspberry Pi DAC Tutorial: Interfacing MCP4725 12-Bit Digital-to-Analog Converter with Raspberry Pi Microcontrollers work only with digital values but in real world we have to deal with Analog signals. That’s why ADC (Analog to Digital Converters) is there to convert real world Analog values into Digital form so that microcontrollers can process the signals. But what if we need Analog signals from digital values, so here comes the DAC (Digital to Analog… |

How to use Digital-to-Analog Converter (DAC) with STM32F10C8 Board We all know that the Microcontrollers work only with digital values but in real world we have to deal with analog signals. That’s why ADC (Analog to Digital Converters) is there to convert real world Analog values into Digital form so that microcontrollers can process the signals. But what if we need Analog signals from digital values, so here comes the DAC (… |

RS485 Serial Communication between Arduino Uno and Arduino Nano Choosing a communication protocol for communication between microcontrollers and peripheral devices is an important part of embedded system. It is important because the overall performance of any embedded application depends on communication means as it is related to cost reduction, faster data transfer, long distance coverage etc. In the previous… |

Arduino Interrupts Tutorial Consider a fast-moving car, if it suddenly gets hit by another car in opposite direction, the first thing that happens is that, the accelerometer sensor present in the car senses a sudden de-acceleration and triggers an external interrupt to the microcontroller present in the car. Then based on that interrupt the microcontroller produces an electric signal to deploy the… |

Automatic Medicine Reminder Using Arduino When it comes to our loved ones, we always want to keep them healthy and fit. But what will happen if they get ill and forget to take medicine on time? We would be worried, right? At hospitals, there are many patients, and it is difficult to remind every patient to take medicine on time. The traditional ways require human efforts to remind them to take medicines on… |

How to Use SPI Communication in STM32 Microcontroller In our previous tutorials, we have learned about SPI and I2C communication between two Arduino boards. In this tutorial we will replace one Arduino board with the Blue Pill board that is STM32F103C8 and will communicate with the Arduino board using SPI bus. In this STM32 SPI Example, we will use Arduino UNO as Slave and STM32F103C8 as Master with Two 16X2 LCD display… |

Rotary Encoder Interfacing with PIC Microcontroller A Rotary encoder is an input device which helps the user to interact with a system. It looks more like a Radio potentiometer but it outputs a train of pulses which makes its application unique. When the knob of the Encoder is rotated it rotates in form of small steps which helps it to be used for stepper/Servo motor controlling, navigating through a sequence of the… |
