Microchip PIC Delay Calculator

Delay Calc Banner

Delays are very essential in the operation of a microcontroller. Because microcontrollers execute instructions at a very fast rate (in microseconds), programmers need to apply delay so that it can interact properly with humans, for example, delay must be used to create software debouncing. Unfortunately, the MPLAB IDE does not have a built-in delay function unlike the Arduino IDE (Arduino …

I’m allowed to do it at home so the college ‘lend’ us the chips.┬áBut after completing the assignment I have to return it (initially I thought the college was going to give the chip to me but I was wrong).

The original version could have easily cost more than RM100. Together with this programmer I also bought a ICSP Universal Socket so I can directly plug it into …

Multimeter

100 7478

Got this relatively cheap digital multimeter at Jalan Pasar for RM 48, including a free 9V battery. There are cheaper ones around RM20 but those looked like it’s gonna break after a few use. I was told that these cheap multimeters are quite accurate when measuring low voltage or current. Let’s put it to the test shall we. This is …
