Lottery Numbers Generator (Flowcode V4)

This basic Flowchart will generate 6 random numbers between 1 and 49. It should never repeat the same number within the 6 generated numbers. If same number is generated within the six, there is a routine to reject it and re-pick another number. If you want to choose a different set of numbers, then ...

How to use I2C LCD. INTRODUCTION I2C bus is very interesting cause it needs only 2 lines of the micro-controller. You can find lots of components (RTC, thermometer, Led dimmer, …). The bus frequency is 100kHz, writing a register will take about 300us. It could be a bit slow for some components, but ...
