    LCD Pinouts

    Many thanks to JimB and Ian for your advice. The chip is a KS0065B and I traced the pins to the connecting pads, and yes pin 1 is GND and pin 2 +5V. All now seems to be well. jada88

    LCD Pinouts

    Thanks again Ian So pin 33 on the KS0066U I trace to the connection pin +5V and pin 23 on chip I trace to connection pin GND to power up the LCD. The other chip pins I can trace to RS,R/W,E,DB0 to DB7 etc to there respective connection pins. jada88

    LCD Pinouts

    As you can see it appears that pin one is connected to + on the PCB. jada88

    LCD Pinouts

    Hi Ian Rogers Many thanks for your quick reply. The only problem is that there is a + sign on pin one and in the corners. Pins 1,2,13 & 14 are marked. Would a photo help? jada88

    LCD Pinouts

    I have some 2x16 LCD's marked UC-16207-GNAR5-1 made by Samsung, I need to know what the pinouts are as I have burnt one out on connecting to my circuit. I cannot seem to find any data on them on line. jada88

    IR Proximity Sensor

    Hi Eric I have a Multi meter ( not the £5 type ) ,ISO-TECH ICT76 meter and a PicoScope 2202. However I have no idea how to use the scope yet, I will have to look for a tutorial. I fully understand the safety implications regarding mains electricty, that is one of the reasons for new circuit...

    IR Proximity Sensor

    Hi Eric Thank you for your advice and time, I will see if I can find the problem with the original PCB.

    IR Proximity Sensor

    To switch on the mirror led the distance was aprox 15 to 50mm from the front of mirror.

    IR Proximity Sensor

    Hi Eric The circuit only powers a LED converter 240VAC in 24VDC out 0.625A. Will the OPB702 work with this circuit.

    IR Proximity Sensor

    Hi Eric Thanks for the circuit. I take it that it uses a photo-diode for sensing, could I still use the OPB702, if not what photo-diode would you recommend? Would a C106D Thyristor be suitable to use in this circuit for the SCR? In the circuit it has LIGHT R11 1000 is this the load (1000W).

    IR Proximity Sensor

    Hi Eric Thanks for your advice. Yes when you place your hand in front of the sensor the light is activated. I have spent a lot of time on line trying to find a circuit so I can make a pcb to replace the original unit. Not very happy with a transformerless unit. Perhaps you can point me in...

    IR Proximity Sensor

    Hi Eric I think the circuit is a break beam. It is in connection with another post I did about a bathroom mirror IR failure. How do I switch on the SSR?
