    20x4 LCD comms

    I notice that LCD's these days communicate via I2C with CLK/DATA. I want just good old Serial. The OLED, however nice, is just too expensive and therefore I opt for LCD display. Where can I look for LCD's with SERIAL (not I2C) comms ? If I use I2C, I will require the device address. What will...

    Alternating Hserin/Hserout and Serin/Serout

    Along the lines of a different thread, can you run either hard serial OR normal serial (on different pin) in the same program ? I am thinking along the lines of a HARD serial routine and NORMAL serial routine where you switch on Serial IN/Serial OUT for a specific pin and then switch it off...

    UV light box - energy saver bulbs

    I have finally built a light box. It has five 11W energy saver "warm white" fluoro bulbs. The bulbs are right alongside each other (almost touching one another) and covers a 250mm area length wise. Distance to the board will be about 100mm from the bulbs. I will expose pre-sensitised board...

    Back after a spell - it ain't easy !

    I have been "out" of Picaxe for a while but now I am back (not with a vengeance...). This is still for the "CHOOK-HOUSE" project. I am having difficulties coding the DS1307 chip. This is what I get from Sertxd...... The actual time is 14H00 + some minutes as w9 is showing....... I have not...
