Ever have trouble programming code for seven segment displays? Well they made the 4511 to make things a whole lot easier. What the 4511 does is takes a ...
Parts: 1.) Arduino 2.) 4511 binary seven segment decoder 3.) Breadboard/jumper wires 4.) Breadboard of some sort (I used a protoshield from Adafruit) 5.) ...
The 4511 takes a four-bit binary input on pins 1,2,6, and 7. Then translates it to a decimal output when connected to a seven segment display, which means ...
For those of you who already are fluent in binary, move on to the next step. Binary is used in pretty much all mainstream electronics today. It is ...
The first thing to do is to build a simple proof of concept circuit, a count up timer, and then go from there, for this, you'll need to ...
Insert the chip into the board, make sure to note which way the chip is facing ( where the little notch is o the chip)
An easy way to do this is just to use some tiny jumper wires for this, so that you don't have them in your way when you insert ...
Pins 3, 16, and 4 are connected to +5v. Pins 8 and 5 are connected to ground.
The 4511 works with common cathode (ground) displays only, but most seven segment displays are, so most of the time, you don't have to worry. A ...
Alright, now for the fun part! Here's the code, just copy and paste after this line. /* Code written and designs made by Kyle Hovey (aka Speleomaniac on ...
I thought it would be cool to take the code from the count up timer, and modify it into a light meter, this is how to do it:
Try bending the leads to the photocell so that it is directed away from the Arduino and display to prevent unwanted light.
A resistor is attached to one lead of the photocell to ground. A wire goes from that same lead to analog input 0 of the Arduino. The other ...
Alright, here's the code, just copy and paste: /* Code written and designs made by Kyle Hovey (aka Speleomaniac on www.instructables.com) For this code, a 4511 binary ...
