It doesn't light up at all. I better check the wiring though as with all those diodes the wiring on the breadboard got a bit fiddly!

It doesn't light up at all. I better check the wiring though as with all those diodes the wiring on the breadboard got a bit fiddly! --- A "gotcha" I noticed yesterday, or the day before is that, wired the way it's shown, (with the register outputs sinking current) if all the register outputs come up reset on power-on, then there won't be enough current to turn on all the LEDs and you'll have to wait for an entire cycle before the thing starts to chase properly. If you've got the pot set to "full slow" that could take about 30 seconds, so it might be working, but since nothing was appearing to happen it looked like it wasn't working. In order have it start right away the shift register outputs should _source_ current, so I fixed the circuit and attached a copy of the new schematic. BTW, with the pot set at midpoint, the thing ought to shift at about a 1Hz rate. Also, here's a simulation of both ways (sink and source and 8 bits, only, but you'll get the point, I'm sure.)

The 74HC194s should have ground on pin 8 and Vcc on pin 16. The 74HC00 should have ground on pin 7 and Vcc on pin 14. --- Good catch. 'HC164s, BTW and, for Ian, Vcc is 5V. So I need to step the voltage down from the 9V source, ie: about a 220ohm resistor from the positive rail to pin 16 on each 164 and the 00? --- I'd feel more comfortable with something like an LM78L05 in the +----[78L05]---+---Vcc |+ | | BAT | [100nF] | | | +-------+------+---GND But if you want to use just a resistor, then it'll need to drop about 4V with 20mA going through it, (neglecting the current drawn by the logic and the drop across its output) so it'll need to have a resistance of: Vin - Vcc 4V R = ----------- = ------- = 200 ohms It 0.02A so 220 is a pretty good idea. --- I just noticed that you wanted to use one resistor per chip. That won't work. You need to connect all of the chips' Vcc's to one end of the resistor and connect the other end of the resistor to +9V. But there's a more serious problem, and that's that anytime there isn't a 20mA load on one of the shift register outputs, Vcc will rise to ~ 9V, which isn't a good thing. Go with a 78L05... JF |
