Many micro-controller projects use lithium ion (li-ion) batteries and we needs a simple way to display the state of charge (SoC) which is how much battery we have left. This is typically displayed on the screen as a partially filled battery icon and optionally a percentage indicator next to it. There are however several challenges…

A simple solution is to use asp.net inline Tags. For Example: Instead for using: document.getElementById(“Label1″) try using: document.getElementById(“<%=Label1.ClientID%>”)

The Bezier Curve formula below can be used to define smooth curves between points in space using line handlers (line P0 to P1 and line P2 to P3). P(t) = (1-t)^3P0 + 3(1-t)^2tP1 + 3(1-t)t^2P2 + t^3P3 At  t=0 you will be at p0, and at t=1 you will be at p3. The function below…
