74LS47N DATASHEET PDF

In the last tutorial we used a 7-segment display and connected this with our Arduino Uno directly. To do this, we used 8 wires. There are two things we want to change now. First, we reduce the number of wires to communicate with the Arduino. This circuit is a binary-to-decimal to 7-segment decoder. It has two task: translate a binary input in a decimal output and prepare the output to connect a 7-segment display directly.

In the last tutorial we used a 7-segment display and connected this with our Arduino Uno directly. To do this, we used 8 wires. There are two things we want to change now. First, we reduce the number of wires to communicate with the Arduino. This circuit is a binary-to-decimal to 7-segment decoder. It has two task: translate a binary input in a decimal output and prepare the output to connect a 7-segment display directly.

The input is a digit in binary format, i. The advantage to use the 74LS47N is, we need only 4 wires for the input, no more. And, we can reduce our array to store the different values. Ground and Vcc. The remaining 3 pins are not in use in this tutorial. Necessary only to connect this pins to Vcc. For more informations please look at the datasheet for the 74LS47N!

The output pins are active LOW! Therefore we must use an 7-segment display with a common anode! You can identify the active LOW state at the negate letters.

We use define a function to set a digit. We start the function with the digit, which we want to see. The digit number and the row numer in our array are the same. The loop pick up each value from the array and send the correct value with digitalWrite to the related pin. The other loop counts down until 0. In both loop a use a different delay.
