Hello,
I have 500V to 1000V DC output from comibination of solar Panels.
Is it possible to design a circuit which will represent 500Volts to 1000Volts DC range in 0V to 10Volts DC so that I can control my output device as per the voltage.
Similar to solar dusk to dawn street light, but high...
Hello,
Noted of heat sink,
Will be trying the same circuit on hardware today,
The DAC was not available to me in local market, so will give input from powersupply
using UA741 as OP_AMP
PSMN004-60B as MOSFET.
Connections on OP_AMP
IN+ will start from 1V and slowly increasing.
VCC+ (in...
Hi Klaus,
Please can you confirm if the below design is suitable for my purpose,
to 0mA to 500mA in resulation of 1mA.
I tried to simulate it in Proteus.
but the software was crashing..was not sure if it was the software problem or the circuit problem.
Thanks for the reply Klaus..
I am suppose to make a Bill of material of this circuit..which I am not that good(not done it before)
Can you please suggest me with part numbers of 10Bit DAC and OPAMP and MOSFET..
you said, Comparator at output? I have added the MOSFET at output? can you please...
Hello All,
Can someone point me to a circuit, where I can pro-grammatically using SPI/I2C/PWM etc protocols set current source from 0mA to 500mA in steps of 1mA.
may be an IC or even transistor-MOSFET based circuit design.
Vin MAX= 24V Vin MIN = 3V
Vout Max= 24V
Iout= 0mA to 500mA in...
any one having KS0108.c for 128x64 graphic LCD which will solve my problem.
the driver i used here for lcd is HDM64GS12 and the the module used is KS0108 so it is not working
i used the ks0108.c but it is only for 64x64 glcd. i want for 128 x 64 GLCD.
Hello Guys,
I need help regarding Interfacing 128x64 Graphic Display and 3x4 keypad with PIC16f877a
i Have designed it as
here i have connected Keypad to port B and LCD to port C and port D.
using the below Code
//this is KBD.c
#byte kbd = 6 // on to port B (at address...
