PIC16F Development Board
In this post I'll show a more general approach for circuits prototyping. Instead of building each individual design to validate its operation why not to design a basic PIC16F877A based Development Board. Current design have all the necessary features of ...
INA219 current sensor with Arduino
Measuring current is a relatively simple task that can be done by connecting a shunt resistor in series with the load and measuring the voltage on this resistor. The voltage is proportional to a load current according to Ohm’s law ...
Arduino Base Converter with 4×4 Keypad and I2C LCD
Arduino hexadecimal to binary Base Converter is a simple design that can be built using 4×4 Keypad and I2C LCD display module. Arduino MEGA board was chosen as a target device. This circuit will wait for a single digit to ...
LCD voltmeter based on ADS1015 with Raspberry Pi
LCD voltmeter with Raspberry Pi and ADS1015 is the topic of this project. Similar design for Arduino platform is available at this link. ADS1015 is a 12 bit ADC chip with 4 analog input channels. The interface with Raspberry Pi ...
BCD to 7 Segment Display Decoder
In this post I'll show how you can drive 7 Segment LED display with PIC16F876A. Instead of using a dedicated IC’s like 4511 we’ll program the micro controller to convert BCD input code 0 – 9 to a 7 Segment LED ...
Making a siren using Arduino
Generating sound patterns with Arduino is a topic of this article. All you need is Arduino compatible board a simple DC buzzer and current limiting resistor. In this project I'll show how to build a police siren using Arduino Mega ...
HC-SR04 Ultrasonic Sensor with Raspberry Pi
Using HC-SR04 Ultrasonic Sensor with Raspberry Pi is a relatively easy task. HC-SR04 is a very popular module that can provide the distance to the object by sending ultrasonic bursts at 40kHz and measuring the time it takes for the ...
Humidity and Temperature Sensor DHT11 with Arduino
Interfacing Humidity and Temperature Sensor DHT11 with Arduino platform is the topic of this post. I’ve published a number of designs with various temperature sensor, both digital and analog. Here you can see how to use LM75A digital sensor with ...
Binary to Hex 7-Segment Arduino
In this post I’ll show you how to build a simple Binary to Hexadecimal converter using common cathode 7-Segment display and Arduino Mega compatible Iduino Mega R3 board. Similar devices should also work ,however I did not test it. The ...
Stepper Motor Interface PIC16F
This article shows a basic interface between PIC16F microcontroller and a unipolar stepping motor using an assembly code. For programming the MCU you'll need PICKIT2 or PICKIT3 device. Similar design for Arduino platform can be found at this link. Instead ...
