Kitchen timer is a simple gadget never thought of breaking down, but it eventually will be. Though it is cheap I have no interest to buy a new one, I asked myself can I make one for my own? Checking the parts stock found all I need were available, the arduino uno, OLED display, one buzzer, 3 push button, 1 on-off switch and 9V battery. This instructable do not describe on how to make it but more on the arduino code, lets look at the major function of kitchen timer, in the photo though it has Chinese characters, you don’t have to understand it known the usage, the two white button set the minutes, top one to count up, down one to count down, when two were pressed reset to zero, the red button start the count and press it again to pause it.”
