The nixie tube can be confusing to a new arduino and electronic builder, so I built a test circuit with LEDs' and then replaced the LEDs' with a single nixie tube. This way you don't have to worry about any issues with the tube and don't have to worry about including a 175 volts power supply. The technology is the same as described for the Nixie tube clock, the key difference being size. Everything is scaled down to fit on your wrist and, while it’s by no means the smallest watch you will buy, it’s definitely one of the coolest big boys toys and retro gadgets you’ll ever wear and surely has to be one of the hottest men’s.
Once your nixie tube provides been tested, connect electronic pin number 11 to pin number 4(Deb), electronic pin 10 to pin number 7(D), electronic pin 9 to pin 6(M), and digital pin number 8 to pin 3(A) on the SN74141 IC chip. Connect 5v from the Arduino to pin 5 of the nick and terrain from the arduino to pin 12 of the chip. Connect the cathodes óf your Nixie tubé to the matching pins on thé SN74141 and connect the the anodé of the Nixié tube to 180vdc+. The IC chip will take a binary input on Chemical, C, B, A and results the matching number of the nixie tube. Lower, Low, Lower, Low for 0. Lower, Low, Lower, High for 1 and so on. If you want to generate two Nixies independently, it will consider up 8 Arduino digital pins or you could use a shift register(observe figure 4) to just use 3 hooks with two nixie tubes. For more information on making use of a change sign up with a nixie tube, visit this instructable. If you use an Arduino Mega, after that you probably will not really need to use a shift sign up. You can provide power to the Arduino from the 12v finish of the convérter or you cán use a individual power supply if you would like to, but it is definitely not necessary.
