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. In order the to get a precise measurement the current sense resistor should be sufficiently … Read more
74HC595 is a discrete shift register IC that can be easily integrated with Arduino platform. Usually shift registers are used to convert a serial data to a parallel output. Additional shift registers can be connected in series extending the number of available I/O’s even more. In this basic setup just one 7-Segment display module with … Read more
Up Down Counter design based on Arduino MEGA compatible board is the topic of this article.it uses 2×16 LCD display to show the counter values and 4×3 keypad to input initial 3 digit number.The counter will count Up/Down according to a chosen direction * – Up,# – Down. Nevertheless the count will stop at “000”. … Read more
Arduino Ohm Meter is one of the simplest circuits that can be built with minimal number of required components. As can be seen from design schematic a standard 2×16 LCD display and 3 resistors are all you need to complete this project. The value of unknown resistor marked with ? will be shown on the … Read more
In this post I’ll show you how to interface a RTC module DS3231 Real Time Clock with Arduino. This particular module uses I2C protocol to transfer current time to a micro controller. DS3231 library and header files should be installed on your computer and included in the code, otherwise you won’t be able to compile … Read more
