Hi (again),
Can someone explain this guy with 2 left hands howto connect a LCD without soldering? I'dd like to test things first. And besides, the only soldering equipment I could find so far is quite a large 30Watt device. Its package sais its suitable for radio/TV's, that kind of stuff. Could I still try to use for finer work such as electronics? Last time I soldered something was 12 years ago.
I have a parallel LCD with 16 little holes. I think I know how to wire it, there are dozens of tutorials. But the connection between the LCD pin and my wiring is... loose.
The first thing I tried was placing it on a male header, which was put on a breadboard. I connected the header pins to the 5Volt, ground, microcontroller, and so on. When I put the Microcontroller on top of the header, it will switch on and display 8 of the 16 black blocks. Although the microcontroller should initialize and writes something to the LCD, I can only see those blocks. I think its because not all pins are making (proper) contact to those header pins. If I move the LCD a tiny little bit it will turn off or display all 16 black blocks.
So, how can I connect the pins properly without soldering yet? So far I have male headers, normal wires, more stiff prototyping cables for the breadboard and male headers. Maybe there are handy components for this? Or another trick?
Regards,
Rick
