Well i added the missing wire on the LCD and have pins 1 and 2 going to ground from 5V when the buttons are pushed but still get nothing on the LCD. I checked all the connections again and everything is wired correctly with the pull up resistors in place too.

I have checked the connections to the LCD and they are all correct but i am still getting the boxes for an output. My push buttons are working, they illuminate and produce 5V to 1 and 2 when pushed. Is this correct or is something still wrong with them?

No lol I have a new chip I got for the harp and want to test if my old one has pins shorted out from my power supply breaking
Re: Laser Harp kits - Batch 2 - 9 left!
I have the buttons working properly now thanks for the help, is there a program you have that will flash the laser harp code back onto the ATMEGA MC?
Re: Laser Harp kits - Batch 2 - 9 left!
There's four pins on the push buttons, power ground and two contact pins. I have red as power black as found and each green goes to one of the contact pins on each button
Re: Laser Harp kits - Batch 2 - 9 left!
I took them off since they cut the voltage too much for the push buttons to illuminate but here is another picture.
Re: Laser Harp kits - Batch 2 - 9 left!
I had to order new push buttons and got them connected. I attached a picture of the buttons, its a bit messy but i dont want to solder anything till i know its correct. The boxes on the LCD disappeared and it is now blank but seems to be more dim. As for...
Re: Laser Harp kits - Batch 2 - 9 left!
My problem was that with the 10k resistors attached not enough volts were getting to the buttons so they weren't powered on. As for the LCD, it did have a row of grey boxes on the bottom but with the buttons connected it reads nothing now. Could this be...
Re: Laser Harp kits - Batch 2 - 9 left!
Thats ok I had a blown power supply so i was in the process of getting a new one. Is it possible to get a more detailed schematic of how the push buttons are wired or possibly some pictures? Its the last piece i have to complete and am having some trouble...
Re: Laser Harp kits - Batch 2 - 9 left!
You can take the top board off but there are no connections under it besides the power input. The ones on the left side are for different laser color blanking and one that im not sure whats for that is only a 2 pin connection. There is only one other...

Re: Laser Harp kits - Batch 2 - 10 left!
I am building a laser harp as part of my senior project and am wondering about what kind of power supply i am going to need. Im not too knowledgeable on this subject so any help would be great
