Whilst I was looking at the ATmega168 datasheet to see if I could improve the NewSoftSerial library speed I came across the analog comparator – this takes a reference voltage at digital input 7 and a voltage to be compared at digital input 6. Any time the voltages are equal (rising or falling – [...] I have been playing with ethernet for the Arduino – I got hold of a Nuelectronics EtherShield and started to make it work. The examples were badly formatted and difficult to read but I learnt a lot of TCPIP and got it working fine. The issue here is that as you are down at the [...] I got the ByVac BV4208 working, the library is here. I got hold of a I2C Real Time Clock module and a two line LCD display. Managed to get them both connected and working. I am now working on adapting the display to I2C using a ByVac BV4208. I found an old LCD thermometer – got it from Maplin many years ago. I hunted for specs on the web but all I could find was that it used a serial data stream. It runs from 1.5V so I used an NPN transistor and a schmitt trigger NAND gate (old 74LS132 chip I had) [...] I heard about the Arduino on the BBC website recently (story) and have been playing with it. It appears to be exactly what I was looking for about ten years ago!. I’ll post here as I achieve anything. |
