Data pins D4 through D7 of LCD1 are directly connected to pins 5, 4, 3 and 2 of Arduino, respectively. Control pins EN and RS of LCD1 are connected to pins 11 and 12 of Arduino, respectively. GPS ...

Connections from D2 to D13 on the Arduino Pro Mini to the corresponding transistors are omitted in the diagram for clarity. Similarly marked points need to be connected together All Transistor, except ...

This Arduino based Real time clock is a digital clock to display real time using a RTC IC DS1307 which works on I2C protocol. Real time clock means it runs even after power failure. When power is ...

You should connect one of signal lines to some pin of Arduino (A1 is used in project). Note that if you play mono sound then it doesn't matter which signal line to use (Left or Right). When reading ...

Its pin 19 is for power supply, pins 4 and 9 are for ground, pin 1 for Data In, pin 12 for Load, and pin 13 for Serial Clock. (The pin details are not shown here.) Pin 24 is Data Out pin for ...

The alarm clock is made using a Arduino Mini and a TFT screen. You can turn the alarm on and off by flipping the clock, it’s charged through a micro USB port, and it even senses your presence ...

Nixie tube clock build has been classed as an intermediate project and should take approximately eight hours to complete using an Arduino MKR WiFi 1010 microprocessor together with IN-1 Nixie ...

Features of the Fibonacci clock include: – The clock is divided into three independents zones: hours, minutes and seconds that use the Fibonacci sequence (1,2,3,5) to simulate counting all the ...
