Looking for heating coil
Ok this is to heat coconut oil in a bottle. The dimensions given are those of the bottle. Oil is in the solid form and I want to melt it. Thinking out loud here if I use H = m x...

Driving LEDs without resistors - acceptable or not?
Can you not use the pull up resistor of another AVR input as the limiting resistor? I remember there was/is a tutorial that shows how to turn an LED on/off using AVR o/p and i/p...

Combining multiple peripheral devices
Well I am going to do it for myself. I was thinking of using customized AVR's for example the AT90PWM series for generating PWM etc. So I was thinking of using push button...

Connecting a STK500 to ATmega32
Also you may want to check if the status LED first blinks and then turns green and if the M32 is in the right socket on the AVR board.

Programming without a clock
I wonder if you can connect to the o/p of a digital/analog watch to get the 32.768kHZ signal for a clock.

problem with ADC
The testBUF variable needs to be declared volatile (not sure if static has the same effect as volatile). Quote: testBuf[a] = ADCH; I am not sure if the order in which you read...

ADC pin with pull up? detecting when nothing is connected
I have used an external pull up (just a simple resistor connected to the 5V supply) to connect to my ADC pin. When the ADC pin is floating, it reads 5V (after conversion in...

How do I unselect the CLKDIV fuse?
I will look at the datasheet but does it work for the 328P?

ADC and timing
Ok I added the (ADCSRA & _BV(ADIF)) != 0 and I still get about 0V for the one pin that should read about 0.1V. Here is what my ADC_init looks like: void ADC_init() {...

ADC and timing
Thanks, guys. Plans, here is my code with the percent sign removed: void timer_init() { TCCR1B |= (1 << WGM12); TIMSK1 |= (1 << OCIE1A); sei();...
