8 CHANNEL PWM LED DRIVERS FOR WINDOWS DOWNLOAD

Ensure it is positioned as shown otherwise it will be in the wrong position to fit the PCB. Can I use less than 8 LEDs? There is no quick and easy change to make it a 9, 12 or some other number of LED chaser. S1 is a 6mm right angle tactile switch, Omron B3F series. Do not solder any connections to or on the PCB while power is applied. You will see a small dot and indent at one end of the body.

Can you modify the code to run on a PIC type xyz? A number of sequences are programmed into the firmware to provide some interesting visual effects and chase sequences, i ncluding the classic effect seen on the car in the Knight Rider TV series. Be sure to connect it up correctly because 8 channel pwm led D1 in place there is no reverse polarity protection.

8 Channel PWM LED Chaser for 16F628A and 16F88

You will need to bend the leads of the LED through 90 o as shown in fig 8. Typical current drawn by 8 channel pwm led circuit with all LEDs on is only around mA so the voltage regulator doesn’t require any additional heatsink.

You can add, remove or edit this data to create your own chaser sequences.

You will see a small dot and indent at one end of the body. The programmer may be unable to drive these lines when lower value resistor are used.

They run exactly the same base code, just use different sequences to suit the layout of the boards. Variable chase speed option kit now available see here for details.

It should be fitted so the notch is in the same direction as the marking on the PCB overlay Fig 6. Initially only solder one lead of 8 channel pwm led LED as shown. In manual mode, 8 channel pwm led the repeat count reaches zero it will restart the same lex, to advance to the next sequence press the switch. Since the current mode and selected channsl are saved to NVRAM, it always powers up in the last mode and running the last sequence. If you’re assembling from the chaannel C1 and C3 are the same value, but can be one of two types and will be marked ” C2 is marked ‘.

You might want to edit this file as a starting point to create some sequences of your own.

I have a couple of them and I wouldn’t use anything else 8 channel pwm led. Since the current mode and selected sequence are saved to NVRAM, it always powers up in the last mode pw, running the last sequence. You might want to edit this file as a starting point to create some sequences of your own.

All components used in this kit can be sourced from Rapid Electronics Standard fhannel are used in this project and should be easy to source cchannel distributors world wide. If you plan on using this inside a PC as a case mod’ you can power it from the PC power supply. Variable chase 8 channel pwm led option see here for details This neat little circuit provides 8 LEDs directly driven from the PIC along with a single mode control switch.

Can you or how can I make it it run more than 8 8 channel pwm led Therefore if you select manual mode and the sequence required, it will run only that sequence until you change it. If you want to modify the source code it 8 channel pwm led be made to run on other Cahnnel types, however we won’t modify the code. You will need to use a suitable DC power supply rated between 8 and 12 volts and able to supply at least mA.

8 Channel PWM LED chaser

A short press of the switch cycles through the three modes. Description of Sequence Data. You can buy all the parts needed to build this project from most component suppliers world wide.

If 8 channel pwm led want to modify the source code it could be made to run on other PIC types, however we won’t modify the code. It is not supplied with the kit. In Random mode it will 8 channel pwm led select a random sequence number to run.

If you need a chaser with more LEDs then this project is not suitable for your needs. In auto-sequential mode, the program runs through 8 channel pwm led sequence in program memory until it reaches the end of all defined sequences at which point it restarts from the first one. The artwork is provided if you want to etch your own board, however it is a double sided board and unless you can thru-plate the holes it will be difficult to solder both sides of some components such as the terminal blocks.
